What is tissue culture?

Question

What is tissue culture?

Answer 1

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 ageing and healing processes;and reactions to physical,chemical,and biological agents(e.g.,drugs,viuruses).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.

Answer 2

It is a culture, of tissue.

It is when tissue is grown in a dish, usually with an agar (food)

Answer 3

Qbert P is correct.

Usually people who ask about cultures are interested in cancer research (http://users.rcn.com/jkimball.ma.ultrane... or burn recovery (http://www.burnsurvivor.com/medical.html... so I included links for those topics.

Answer 4

It is a culture of tissue fragments or cells grown or kept alive in an artificial environment for examination and/or manipulation.

Botany specific:

Plant tissue culture/micropropagation is used to cultivate plants under sterile conditions, often used to propagate orchids or carnivores e.g. from seeds or to clone plants from totipotent cells ( special cells, able to regenerate a complete plant )
