Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. The lifespan of most cells is genetically determined, but some cell-culturing cells have been 'transformed' into immortal cells which will reproduce indefinitely if the optimal conditions are provided.
Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed. In animal tissue culture, cells may be grown as two-dimensional monolayers (conventional culture) or within fibrous ...
Conventional methods for growing animal tissue in culture involve the use of fetal bovine serum (FBS). FBS is a blood product extracted from fetal calves. This product supplies cells with nutrients and stimulating growth factors, but is unsustainable and resource-heavy to produce, with large batch-to-batch variation. [21]
The substance used to embed tissue is embedding media, which is chosen depends on the category of the microscope, category of the micro tome, and category of tissue. [23] Paraffin wax, whose melting point is from 56 to 62°C, is commonly used for embedding. [22] Tissue processing - Tissue sections on slides are stained on an automated stainer
Agricultural biotechnology, also known as agritech, is an area of agricultural science involving the use of scientific tools and techniques, including genetic engineering, molecular markers, molecular diagnostics, vaccines, and tissue culture, to modify living organisms: plants, animals, and microorganisms.

Because the tissue cultures far outlived their organisms, they were deemed “immortal.” Burrows and Carrel went on to expand the application of their tissue culture techniques to additional types of tissues including: adult tissues, tissues of mammalian origin, and cancerous tissues from chicks and humans.

Additionally, increased financing for life science research results in a greater range of studies and experiments, most of which include cell cultures. The necessity to maintain and store these cultures under strict conditions necessitates the use of high-end, specialized cell culture media storage containers, which are a crucial component of ...
Two major alternatives to in vivo animal testing are in vitro cell culture techniques and in silico computer simulation; however, some claim they are not true alternatives because simulations use data from prior animal experiments and cell cultures often require animal derived products, such as serum or cells. Others say that they cannot ...
