Cells growing in tissue culture

Epithelial cells being cultured

Tissue culture or cell culture is a way to grow cells in a laboratory. Cells are taken, and put into in a flask or Petri dish. They can be grown on a growth medium, sometimes an agar plate. The cells divide, and can be treated in various ways. This is done for a number of purposes, especially for the use of scientific research:

• Growing bacteria or fungi for experiments or for identification. An example would be growing bacteria to see what antibiotics they are resistant to.
• Growing cells of plants or animals for various experimental purposes.
  • Plant cuttings can be grown: roots grow out of a sprig.
  • In-Vitro Fertilization is when eggs are taken and fertilized with sperm in the dish.
