tissue culture

noun    (Concise Encyclopedia)

Biological research method in which tissue fragments (a cell, a population of cells, or all or part of an organ) are sustained in an artificial environment for examination and manipulation of cell behaviour. It has been used to study normal and abnormal cell structure; biochemical, genetic, and reproductive activity; metabolism, functions, and aging and healing processes; and reactions to physical, chemical, and biological agents (e.g., drugs, viruses). A tiny sample of the tissue is spread on or in a culture medium of biological (e.g., blood serum or tissue extract), synthetic, or mixed origin having the appropriate nutrients, temperature, and pH for the cells being incubated. The results are observed with a microscope, sometimes after treatment (e.g., staining) to highlight particular features. Some viruses also grow in tissue cultures. Work with tissue cultures has helped identify infections, enzyme deficiencies, and chromosomal abnormalities; classify brain tumours; and formulate and test drugs and vaccines.
