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.
Growing cells in the laboratory is known as cell culture.

The cells divide and spread over the surface of the dish.rowing cells in the laboratory is known as cell culture.
