We describe a method of growing an animal cell in a culture medium, in which the culture medium comprises an elevated concentration of a thymidine family member, in which the growth or viability of the animal cell is increased as a result of the elevated concentration of the thymidine family member in the cell culture medium. Preferably, the cell culture medium comprises a semi-solid medium, which is a serum free or chemically defined medium. |
