What Is Tissue Culture

Contents

tissue culture

When bits of tissue from an animal or plant are transplanted to an artificial environment where they may continue to exist and function, this is referred to as tissue culture. Alternatively, the culturedtissue might be made up of a single cell, a population of cells, or a full or portion of an organ or organ organ. It is possible for cells grown in culture to proliferate; change in size; change in shape; change in function; display specialized activity (muscle cells, for example, may contract; or interact with other cells).

Historical developments

German scientist Wilhelm Roux attempted the first tissue culture experiment in 1885, growing tissue from a chick embryo in warm salt solution. Roux’s experiment was a success, and tissue culture became widely used after that. Nevertheless, it was not until 1907 when an American naturalist named Ross G. Harrison confirmed the development of frognerve cell processes in the presence of clotted lymph. Harrison’s approach was later improved upon by French surgeon Alexis Carreland and his colleague Montrose Burrows, who reported their early findings in a series of articles published in 1910–11, detailing their initial breakthroughs.

Following that, a number of experimenters were successful in growing animal cells, employing a range of bodily fluids as culture medium, including lymph, blood serum, plasma, and tissue extracts, among others.

Because of these achievements, researchers were able to produce and maintain human embryonic stem celllines, which helped them get a better knowledge of human biology and made significant advancements in therapeutics and regenerative medicine.

Primary cultures and established cell lines

There are two types of cultures: primary (mortal) cultures and cultures of established (immortal) cell lines. Primary (mortal) cultures are the most common type of culture. Basic cell, tissue, and organ cultures are made up of normal cells, tissues, and organs that have been excised directly from tissue that has been harvested by biopsy from a living creature. Primary cultures have the benefit of closely replicating the normal function of the cell, tissue, or organ under investigation. However, the longer the samples are kept in culture, the greater the number of mutations they acquire, which can result in alterations in chromosomal structure as well as cell function.

  • Cells go through an aging process in which they reproduce for only 50 to 100 generations at a time, after which their reproduction rate drops dramatically.
  • Cell lines that have been created, on the other hand, may be maintained forever.
  • Cells in established lines accrue mutations over time, in a similar way as cells in initial cultures, and these mutations can alter the nature of the cells.
  • The DNA profile of the grown cells is compared to a known or standard profile for that cell line, which is known as authentication, in order to determine whether or not the cells are of that line.

Tissue culture – Wikipedia

Flasks holding tissue culture growth media, which offers sustenance for the development of cells in the culture medium. Tissue culture is the process of growing tissues or cells in a culture medium that is distinct from the original organism. Micropropagation is a term used to describe this procedure. In most cases, the use of a liquid, semi-solid, or solid growth medium, such as brothoragar, helps to facilitate this process. Cell and tissue culture are terms that are generally used to refer to the cultivation of animal cells and tissues, with the more specific phrase plant tissue culture being used for the growth of plant cells and tissues.

Historical use

A portion of themedullary plate from an embryonic chicken was taken and kept in a warm saline solution for many days by Wilhelm Roux in 1885, establishing the fundamental principle of tissue culture in the process. A demonstration of the proliferation of frog embryonic cells that would eventually give birth to nerve cells in a medium of clotted lymph was made by the naturalist Ross Granville Harrison in 1907. In 1913, E. Steinhardt, C. Israeli, and R. A. Lambert discovered that guinea pigcorneal tissue could be used to grow vacciniavirus.

Plant tissue culture was pioneered by Gottlieb Haberlandt, who was the first to recognize the potential of isolated tissues cultured in vitro.

The realization of methods for tissue and cell culture has occurred since Haberlandt’s original declarations, resulting in substantial advances in biology and medicine.

His initial concept, which was introduced in 1902, was known as totipotentia: “Theoretically, all plant cells are capable of giving rise to a full plant,” he explained.

Modern usage

Tissue culture is a term that is commonly used nowadays to refer to the growth of cells from a tissue obtained from a multicellular creature in vitro. These cells may be cells extracted from a donor organism (primary cells) or cells derived from an animmortalized cell line (animmortalized cell line). During the culture process, the cells are immersed in a medium that includes critical nutrients and energy sources that are required for the cells’ survival. As a result, in its broadest sense, the terms “tissue culture” and “cell culture” are frequently used interchangeably.

It gives an in vitromodel of the tissue in a well-defined environment that can be readily modified and examined, allowing for more accurate results.

A 1988 NIH SBIR award report by Eric Simon demonstrated that electrospinning could be utilized to construct nano- and submicron-scale polymeric fiber scaffolds that were specially designed for use as in vitro cell and tissue substrates in a variety of applications.

They discovered that, in contrast to the flattened morphology commonly found in 2D culture, cells grown on electrospun fibers displayed a more rounded 3-dimensional shape, which is more similar to the morphology of tissues in the wild.

Tissue Culture Technology

Every plant, just like every individual is different and one-of-a-kind, is also unique. Some have characteristics like as improved color, yield, or insect resistance. Scientists have been searching for technologies that would allow them to create perfect replicas of these exceptional individuals for many years. Plants normally reproduce by generating seeds, which is a process known as sexual reproduction. In other words, pollen from the stamens of the plants fertilizes the egg cells in the flowers of the plants.

DNA from both parents is mixed in unforeseen and novel ways during sexual reproduction, resulting in the creation of distinct plants.

Several of us believe that all plants are propagated from seeds. In recent years, researchers have devised various ways for generating perfect replicas of plants that do not require the use of seeds. And scientists are now accomplishing this with the use of a technique known as “tissue culture.”

What is Tissue Culture?

It is the growing of plant cells, tissues, or organs on specially prepared nutritional medium that is referred to as tissue culture (TC). Under the correct circumstances, it is possible to regenerate a whole plant from a single cell. Plant tissue culture has been around for more than 30 years and is a relatively simple procedure. When it comes to the development of disease-free, high-quality planting material as well as the quick production of large numbers of homogeneous plants, tissue culture is considered a critical technique for developing nations.

  • It is possible to create thousands of duplicates of a plant in a short period of time in this manner.
  • They also have a shorter and more consistent production cycle, and generate larger yields.
  • Its implementation needs simply a sterile workplace, nursery, and greenhouse, as well as highly trained personnel.
  • Oil palm, plantain, pine, banana, date, eggplant, jojoba, pineapple, rubber tree, cassava, yam, sweet potato, and tomato are among the plants that have been grown in tissue culture and are important to developing countries.
  • This application of traditional biotechnology is the most widely used kind of traditional biotechnology in Africa.

Uses of TC technology in Asia

  • TC is the growing of plant cells, tissues, or organs in nutritional medium that has been particularly designed for this purpose. One cell can be used to regrow a whole plant if the conditions are favorable. For more than three decades, plant tissue culture has been used to study plants. When it comes to the development of disease-free, high-quality planting material as well as the quick production of large numbers of homogeneous plants, tissue culture is considered a crucial technique for developing countries. Micropropagation, which is a kind of tissue culture, increases the quantity of planting material available for distribution and large-scale planting, allowing for more efficient distribution and planting overall. Plants that can be reproduced in mass quantities in a short period of time are known as clones. Micropropagated plants are seen to establish more quickly, develop more aggressively, and stand taller than conventionally propagated plants. They also have a shorter and more consistent production cycle, as well as greater yields. Many poor nations have already mastered the process of plant tissue culture, which is a simple one. Only a sterile workplace, nursery, and greenhouse, as well as highly trained personnel, are required for its implementation. Unfortunately, tissue culture is a time-consuming and expensive process that requires a lot of effort. Oil palm, plantain, pine, banana, date, eggplant, jojoba, pineapple, rubber tree, cassava, yam, sweet potato, and tomato are examples of plants that are vital to poor nations and have been cultivated in tissue culture. Among traditional biotechnology applications in Africa, this is the one that is most widely used:

Benefits of TC technology for small-scale banana producersin Kenya(Source: ISAAA)

When it comes to food crops, bananas are extremely essential in Kenya and many other countries of the tropical and subtropical developing globe. However, during the previous 20 years, there has been a significant fall in banana output, owing to extensive soil deterioration and the infection of banana plants with pests and diseases. Adding to the difficulty was the widespread practice of cultivating new banana plants from sick suckers, which exacerbated the situation. Food security, employment, and income in banana-producing areas were jeopardized as a result of the crisis.

With adequate pest and disease control and field cleanliness, yield losses caused by pests and diseases have been decreased significantly at the farm level.

When it came to supplying adequate quantities and quality of such materials, tissue culture technology was deemed a suitable choice. Yield losses caused by pests and illnesses have been decreased significantly at the farm level as a result of good management and field hygiene procedures. Farmers now have access to the following resources thanks to advances in tissue culture technology:

Banana is a very significant food crop in Kenya, as it is in many other regions of the tropical and subtropical developing world. Banana output has experienced a dramatic fall in the last 20 years, owing to extensive soil deterioration and the infection of banana plants with pests and diseases. These issues were exacerbated even more by the widespread practice of growing new banana plants from sick suckers. In banana-producing communities, the scenario was endangering food security, employment, and revenue.

Benefits of TC technology for rice farmers in West Africa (Source: WARDA)

Over the course of several decades, scientists have fantasized about fusing the ruggedness of the African rice species (Oryza glaberrima) with the productivity of the Asian rice species (Oryza edulis) (Oryza sativa). However, the two are diametrically opposed. Attempts to cross them were unsuccessful since the offspring produced were all infertile. When rice breeders from the West Africa Rice Development Association (WARDA) faced infertility issues in the 1990s, they resorted to biotechnology in an attempt to address the problem.

Scientists were able to cross these two species thanks to advancements in agricultural research.

Once the fertility of the offspring had been enhanced (typically after several cycles of back-crossing), anther cultivation was employed to double the gene complement of the male sex cells (anthers) and, as a result, generate true-breeding plants, which were then sent to the field.

Some of the new plants blended the yield characteristics of the sativa parent with the characteristics of the glaberrima parent to produce hybrids with higher yields.

  • It has been a long-held ambition of scientists to combine the hardiness of the African rice species (Oryza glaberrima) withthe productivity of the Asian rice species (Oryza sativa) (Oryza sativa). They are diametrically opposed to one another, though. When they were crossed, all of the children were born infertile, which ended up being a costly failure. When rice breeders from the West Africa Rice Development Association (WARDA) faced reproductive issues in the 1990s, they resorted to biotechnology in an attempt to solve the problem. The success of the initiative was dependent on gene banks that held seeds from 1,500 different African rice varieties — which were on the verge of extinction since farmers had previously abandoned them in favor of higher-yielding Asian varieties — as well as other resources. These two species were crossed thanks to technological advances in agricultural research. A procedure known as “embryo-rescue” was used to retrieve embryos from the two species’ cross-fertilizations and grow them on artificial medium. The resulting plants were re-crossed with the sativa parent whenever feasible due to the fact that they were usually practically infertile (knownas back-crossing). As soon as the fertility of the progeny was enhanced (which was usually achieved after a few of cycles of back-crossing), anther cultivation was utilized to double the gene complement of the male sex cells (anthers) and, as a result, to generate true-breeding plants. NewRice for Africa (NERICA) was the first of the new rice varieties to be made available for testing in 1994, and since then, a large number of different lines of the rice have been developed. Certain new plants blended the yield characteristics of the sativa parent with the characteristics of the glaberrima parent to produce hybrids with higher yields and greater local adaptability. NERICAs are characterized by the following features in the majority of instances:

Glossary

Anther: The most important male reproductive structure, in which pollen is produced and preserved. Apical meristems are found at the tips of roots and stems, where new cells are produced. DNA is a molecule present in the cells of living beings that stores genetic information (also known as genetic material). In plant breeding, embryo rescue refers to a series of tissue culture procedures that are used to allow an unfertilized immature embryo arising from an interspecific cross to continue growing and developing until it may be regenerated into a full plant.

Rhinovirus

Many strategically important laboratories and institutes employ tissue culture (TC) to grow and trade virus-indexed TC plantlets, which are used in a variety of research and development applications (Frison, 1994). Advances in Virus Research, Volume 14, Number 1, 2014

Virus Isolation in Tissue Culture

The detection of rhinoviruses in tissue cultures is carried out using human diploid embryonic lung fibroblasts (WI-38, MRC-5) or HeLa cells, which are derived from human diploid embryonic lung fibroblasts (WI-38, MRC-5). Rhinoviruses grow most efficiently at temperatures of 33°C or 34°C, and when cultures are incubated in rolling drums. After incubation, cultures are maintained for 10 to 14 days, at which time the cytopathic effect can be detected. Rhinovirus growth sensitivity may vary amongst tissue cultures, and different batches should be tested for this trait.

As previously noted, rhinovirus species A and B may be cultivated in tissue culture; however, rhinovirus species C does not develop in normal cultures and must be detected using molecular methods instead.

Growth of Measles Virus in Tissue Culture

Enders and Peebles were the first to successfully isolate MV in the laboratory, which occurred in 1954. 18 After being propagated in primary human renal cells, the virus was transferred to cultured simian kidney cells for further development. WT MV is a challenging virus to replicate in vitro due to its sluggish growth rate and the fact that only a small number of cell cultures are permissive for the virus. 16 MV intissue cultures often create stellate cells with enhanced refractility and, especially after passage, multinucleated syncytial giant cells with intranuclear inclusions as a result of the cytopathic effects.

Typing using monoclonal antibodies and performing immunofluorescence or plaque reduction assays on suspected MV isolates are the two most common methods of identifying the virus.

3,19 Assays for MV using reverse transcriptase polymerase chain reaction (RT-PCR) are also readily accessible (see later).

Tissue Culture of Disease-Resistant Plants

Fruit and vegetable plants that are clonally propagated, such as strawberries, apples, bananas, sugar cane, cassava, and potatoes, benefit greatly from tissue culture of disease-resistant plants. Growing a large number of plantlets from meristem and other tissue cultures allows for the rapid multiplication of plants with exceptional (resistant) genotypes, which is especially useful in crops that are difficult to reproduce via seed. Another application for tissue culture is the generation of pathogen-free stocks of clonally propagated sensitive plants, which is becoming increasingly popular.

Isolation of Disease-Resistant Mutants from Plant Cell Cultures

Plants that have been regenerated from culture (calluses, single cells, or protoplasts) can exhibit significant diversity (somaclonal variation), most of which is either ineffective or harmful. Plants with beneficial properties, on the other hand, may also arise. Plants regenerated from the leaves of a potato variety sensitive to bothPhytophthora infestans andAlternaria solani, for example, were shown to be resistant to both pathogens (5 out of 500 plants) and to P.

infestans (20 out of 800 plants), respectively. Similarly, plants with improved resistance to disease caused by the bacteria Cochliobolus and Ustilago were grown from sugar cane tissue cultures.

fCulture Dishes

The use of tissue culturedishes for egg culture processes is common practice. For egg collection and “washing,” small 35mm tissue culture plates (e.g., Corning 35mm10mm polystyrene, No. 25000) are filled with approximately 3mL of media and used as a collecting vessel. In order to contain large numbers of eggs before and after microinjection, larger dishes (e.g. Corning 60mm15mm polystyrene, sterile tissue culture plates, No. 25010) are employed in addition to shorter dishes. Medium (20–50L in microdrops) is put in plates with silicone oil coated on top to keep the eggs from breaking while they are being worked on.

  1. It is common practice to utilize silicone oil (e.g., 200 Fluid; Dow Corning, Midland, MI) since it is inexpensive and effectively reduces dispersion and evaporation of the microdrops.
  2. Instead of using BSA in the medium, use a 1:1 amount of silicone oil and medium and shake violently for 15 minutes before allowing the mixture to sit overnight to wash out any residue.
  3. After the microdrop dishes have been made, they are put in a temperature- and gas-controlled environment to allow them to dry.

What is Tissue Culture?

Plant tissue culture is a specific technique for plant propagation that is employed in laboratories. It works on the premise of growing disease-free plant tissues in sterile circumstances in an artificial plant growth medium to produce a disease-free plant product.

Tissue Culture at a Glance

  • Identifying and verifying that a superior plant possesses and maintains all of the development traits specific to the variety is the first step. We identify these plants as the mother plants or as the donors of plant tissues for the purpose of initiating the tissue culture procedure. The mother plant should be in good condition and free of any microbes before she may produce seeds. A disease-testing protocol in the laboratory is followed to ensure that the meat is clear of bacteria, viruses, and other disease-causing organisms. A growing point or meristem is plucked from a plant and put into culture flasks with proper nutritional medium and growth encouraging conditions
  • This procedure is repeated several times. The plant tissues develop on a nutrient-dense culture media in a sterile environment
  • Bacteria and fungus are excluded from the mother plant during the development process of the plant. As a result, all operations are carried out under sterile circumstances in order to prevent these organisms from interfering with the growth of the plant tissue.

Advantages and Disadvantages of Plant Tissue Culture

What is Plant Tissue Culture and how does it work? It is possible to create new platelets by using plant material in a growth media, which is called Plant Tissue Culture. An very specialized and carefully regulated environment is used to cultivate and grow the starting plant material. The Tissue Culture Process, also known as micropropagation, is a technique that allows you to produce numerous homogeneous plants in a short period of time. A benefit of this procedure is that it may be used by impoverished nations to enhance agricultural yields, by individual at-home growers who want to create consistent quality, and by enterprises that want to manufacture identical clones of a species for a profit.

The effectiveness of the tissue culture procedure is highly dependent on the availability of a sterile environment and a suitable growth media.

This procedure is often more faster, and farmers may generate a large number of plants in a short period of time.

Examine the benefits and drawbacks of the tissue culturing procedure.

When it comes to adopting the tissue culture procedure, there are various benefits to consider. We’ve previously spoken about how good it is in assisting poor nations in increasing food production, but what are some of the other benefits that may be important to you as well?

  • In a short period of time, the new plantlets can be raised to maturity. Only a little quantity of plant tissue is required at the start of the process. New plantlets and plants have a higher likelihood of being free of viruses and illnesses than their predecessors. The procedure is not dependent on the seasons and can be carried out at any time of the year. You simply require a tiny amount of area to complete the procedure (ten times the number of plants in one-tenth the amount of space)
  • When applied on a wider scale, the tissue culture procedure contributes to the availability of novel subspecies and varieties to the consumer market. It is more successful for those who want to grow difficult plants, such as specialized orchid breeds, using the tissue culture procedure than than standard soil cultivation methods

Disadvantages of Tissue Culture

  • Tissue culture may necessitate more work and result in a higher financial outlay. Because of the sort of environment in which the plants are produced, there is a possibility that the propagated plants will be less disease resistant. It is critical that the material be tested prior to being cultured
  • Failing to do so might result in the new plants becoming infected with the pathogen that was missed during screening. While the success rate with tissue culture is high if the proper protocols are followed, there is no assurance that the process will be successful. There is still a potential that the procedure will cause a secondary metabolic chemical reaction, causing the growth of the new explants or cells to be slowed, if not completely destroyed

As you can see, the positives appear to exceed the drawbacks in this case study. Getting started with DIY tissue culture may necessitate a little investment of time and money, but the benefits far transcend any initial investment of money. Taking a look at the Tissue Culture Process, let’s try to simplify some of the more difficult words into something that’s a little more palatable. Let’s start from the beginning: there are two basic categories of cultures: indigenous and nonindigenous.

  • Primary culture refers to healthy tissues that have been taken from live substances or from living creatures. According on the procedure used in plant tissue culture, this might be either the leaves or other parts of the plant being cultured.
  • Growing Established Cell Lines: This form of tissue culture involves the growth of primary cells that have already been mutated (even from tumors or biopsies) and are capable of reproducing themselves.

Introduction to Cell Culture – NL

Cell culture is the process of removing cells from an animal or plant and allowing them to develop in a suitable artificial environment once they have been removed. Before culture, cells can be isolated directly from the tissue and disaggregated using enzymes and/or mechanical methods. Alternatively, cells can be isolated from an existing cell line or cell strain and cultivated in the same way that they were originally isolated. Primary culture refers to the stage of the culture after the cells have been separated from the tissue and have multiplied under the suitable circumstances until they have taken up the whole accessible surface area of the substrate (i.e., reachconfluence).

Upon the completion of the first subculture, the primary culture is known as a cell line or a subclone.

It is possible to transform a cell line into a cell strain by selectively cloning or using other methods to isolate a subpopulation of the cell line from the rest of the culture.

Additional genetic alterations are frequently acquired by a cell strain after it has been established as a part of the parent line.

Finite vs Continuous Cell Line

A limited number of times in normal cells before they lose their capacity to multiply, which is a genetically regulated phenomenon known as senescence; these cell lines are referred to as finite. Although some cell lines become immortal naturally, some cell lines become immortal by a process known as transformation, which can occur spontaneously or be driven chemically or virally. The transformation of a finite cell line into a continuous cell line occurs when the cell line gains the ability to divide endlessly as a result of the transformation.

Culture Conditions

The culture conditions for each cell type differ significantly, but the artificial environment in which the cells are cultivated always consists of an appropriate vessel that contains the following components:

  • A substrate or medium that provides the required nutrients (amino acids, carbohydrates, vitamins, and minerals)
  • Growth factors
  • Hormones
  • Gases (oxygen and carbon dioxide)
  • And other substances (such as oxygen and carbon dioxide). It is necessary to have a controlled physico-chemical environment (pH, osmotic pressure, temperature).

Adherent or monolayer culture is required for the majority of cells, which must be attached to a solid or semi-solid substrate (adherent or monolayer culture), while some can be grown floating in the solution (floating culture) (suspension culture).

Cryopreservation

If there is an excess of cells available after subculturing, they should be treated with a suitable protective agent (e.g., DMSO or glycerol) and kept at temperatures below –130°C (cryopreservation) until they are required again. Refer to theGuidelines for Maintaining Cultured Cells for further information on subculturing and cryopreservation of cells.

Morphology of Cells in Culture

It is possible to classify cells in culture into three fundamental types depending on the shape and appearance of the cells (i.e.,morphology). Bipolar or multipolar fibroblastic (or fibroblast-like) cells have elongated forms and grow connected to a substrate, whereas fibroblastic cells do not. A polygonal structure with more regular proportions characterizes epithelial-like cells, which develop in distinct patches linked to a substrate as they expand. Lymphoblast-like cells are spherical in form and are often cultivated in suspension, without adhering to a surface, in order to maximize their growth potential.

Applications of Cell Culture

When it comes to cell culture, it is one of the most important tools in the field of cellular and molecular biology. It provides excellent model systems for studying the normal physiology and biochemistry of cells (for example, metabolic studies, aging), the effects of drugs and toxic compounds on the cells, as well as the mutagenesis and carcinogenesis of cells, among other things. It is also employed in the screening and development of pharmaceuticals, as well as the large-scale production of biological substances (e.g., vaccines, therapeutic proteins).

Plant Tissue Culture

Tissue culture and cell culture of plants are used to describe the sterile development and multiplication of plant cells, tissues, and organs in a laboratory setting. Plant cells cultivated in nutritional medium in an artificial environment may be clonally propagated at a large scale, allowing for the production of more mature and disease-free plants in a shorter amount of time. Molecular genetic engineering, plant breeding, horticulture production, and environmental conservation all benefit from the ability to produce high-quality, homogeneous planting materials quickly.

A gel substrate, such as Murashige and Skoog (commonly referred to as MS media, MSO, or MS0), or Gamborg B5 medium, is used in a variety of typical plant cell culture techniques, including seed culture, meristem culture, callus culture, bud culture, and other types of plant cell culture.

Depending on the exact plant requirements, the plant culture medium formulation may comprise macronutrients, micronutrients, vitamins and organic supplements, amino acids and nitrogen supplements, plant growth hormones and plant growth regulators (PGRs), among other things.
