What is Tissue Culture?


Tissue culture, also known as cell culture or in vitro cultivation, is a scientific technique used to grow and maintain cells, tissues, or organs outside their natural environment, typically in a laboratory setting. This method allows researchers to study the behavior and characteristics of cells under controlled conditions, providing valuable insights into various biological processes.

History of Tissue Culture

The concept of tissue culture can be traced back to the late 19th century when German scientist Wilhelm Roux successfully cultured a frog embryo in a saline solution. However, it wasn’t until the early 20th century that significant advancements were made in the field.

Early Developments

In 1907, American zoologist Ross Granville Harrison pioneered the technique of tissue culture by successfully growing frog nerve cells in a hanging drop culture. This breakthrough opened up new possibilities for studying cell behavior and laid the foundation for future advancements in the field.

In the following decades, various scientists made significant contributions to tissue culture techniques. Alexis Carrel, a French surgeon, developed methods for cultivating whole organs and tissues, including heart muscle and blood vessels. Harry Eagle, an American researcher, formulated specific nutrient media to support the growth of different cell types.

Modern Tissue Culture Techniques

With advancements in technology and the understanding of cellular biology, tissue culture techniques have become more refined and versatile. Today, researchers can culture a wide range of cell types, including animal, plant, and human cells.

Modern tissue culture methods involve the use of specialized equipment, such as sterile containers like Petri dishes or culture flasks, nutrient media, and controlled environments with regulated temperature, humidity, and pH levels. These conditions mimic the natural environment necessary for cell growth and proliferation.

Applications of Tissue Culture

Tissue culture has revolutionized various fields, including medicine, agriculture, and biotechnology. Its applications are diverse and continually expanding. Some of the key areas where tissue culture plays a crucial role are:

Medical Research and Drug Development

Tissue culture is extensively used in medical research to study diseases, test potential drugs, and develop treatments. Cultured cells can be manipulated and exposed to various substances to observe their effects, providing valuable insights into disease mechanisms and potential therapeutic interventions.

Drug development also heavily relies on tissue culture techniques. Researchers can screen thousands of compounds using cell-based assays, helping identify potential drug candidates and accelerating the drug discovery process.

Organ Transplantation

Tissue culture plays a vital role in organ transplantation. By culturing cells and tissues, it is possible to expand the available pool of organs for transplantation. For example, skin cells can be cultured to provide grafts for burn victims, reducing the need for extensive skin grafting from the patient’s own body.

Furthermore, tissue culture allows for the study of rejection mechanisms and the development of immunosuppressive drugs, improving the success rate of organ transplantation.

Plant Breeding and Agriculture

Tissue culture has revolutionized plant breeding and agriculture. Through techniques like micropropagation, large numbers of genetically identical plants can be produced from a single parent plant. This method is particularly useful for propagating rare or endangered plant species.

In addition to propagation, tissue culture is employed in the development of disease-resistant plant varieties, the production of genetically modified crops, and the preservation of plant germplasm through cryopreservation.

Biotechnology and Industrial Applications

Tissue culture techniques are extensively used in biotechnology and industrial applications. Cultured cells are utilized for the production of pharmaceuticals, enzymes, vaccines, and various other products.

Cell lines derived from tissue culture are also crucial for the study of genetic disorders, cancer research, and the development of tissue engineering and regenerative medicine approaches.

Tissue Culture Techniques

There are several techniques and variations of tissue culture, each tailored to specific cell types and research objectives.

Cell Culture

Cell culture involves the growth and maintenance of isolated cells in a controlled environment. These cells can be derived from various sources, such as animals, plants, or humans. The cells are typically suspended in a nutrient-rich medium and incubated under specific conditions.

Primary Cell Culture

Primary cell culture involves directly isolating cells from living tissue and culturing them. This technique allows the study of cells in their native state and is particularly useful for studying cell behavior and function.

Cell Line Culture

Cell lines are cells that have been immortalized through genetic modifications or through continuous subculturing. These cells can divide indefinitely, making them valuable for long-term experiments and large-scale production.

Organ Culture

Organ culture involves the cultivation of intact organs or tissue slices in a controlled environment. This technique allows researchers to study organ-specific functions and interactions between different cell types.


Explants are small pieces of tissue, such as leaf fragments or sections of an organ, that are cultured. This technique enables the study of tissue-specific responses and interactions.


Co-culture involves the simultaneous cultivation of two or more cell types in close proximity. This technique allows the study of cell-cell interactions and complex biological processes.

Three-Dimensional (3D) Culture

Three-dimensional culture techniques aim to mimic the natural environment of cells more accurately. Cells are grown in a matrix or scaffold that provides structural support, allowing them to form complex tissue-like structures.

Commonly Used Tissue Culture Media

Tissue culture media are nutrient-rich solutions that provide the necessary nutrients, growth factors, hormones, and buffering agents required for cell growth and survival. Different cell types require specific media formulations to support their growth. Some commonly used media include:

  • Dulbecco’s Modified Eagle Medium (DMEM): A widely used medium for mammalian cell culture.
  • Roswell Park Memorial Institute (RPMI) 1640: Designed for the growth of human and animal cells.
  • Minimum Essential Medium (MEM): Suitable for a wide range of mammalian cells.
  • Basal Medium Eagle (BME): Used for primary cell culture and the growth of certain cell lines.
