How are cells supplied with proper nutrients in cell culture?
By providing amino acids, minerals, vitamins, salts, glucose, etc., and serum containing insulin and growth factors
What does serum contain in cell culture?
Insulin and growth factors
What happens during the process of contact inhibition in cell culture?
Cells are unable to divide further due to being closely packed
What is primary cell culture?
Cells taken directly from an organism that usually divide a limited number of times (~50 generations)
