Cell culture. Cell culture, the maintenance and growth of the cells of multicellular organisms outside the body in specially designed containers and under precise conditions of temperature, humidity, nutrition, and freedom from contamination.
In its simplest form, cell culture involves the dispersal of cells in an artificial environment composed of nutrient solutions, a suitable surface to support the growth of cells, and ideal conditions of temperature, humidity, and gaseous atmosphere.issue culture was first developed in the early 1900âs as a method for studying the behavior of cells â free of the variations that might arise in the whole organism â in reponse to normal and induced experimental stress.
