Human AML colony growth in serum-free culture.
Here we report experiments dealing with the development of a fully serum-free culture system for AML cell proliferation. A number of compounds were tested for the requirements of AML colony formation and DNA synthesis in vitro in an attempt to replace serum with an artificial mixture. The results indicate that bovine serum albumin (BSA, 15 mg/ml), cholesterol (7.8 micrograms/ml), transferrin (7.7 X 10(-6) M) and insulin (1 microgram/ml) were essential for AML cell proliferation. Linoleic acid, 2-mercaptoethanol and selenite contributed only moderately beneficial effects. This mixture obviated the need for adding exogenous fetal calf or horse serum to the cultures and permitted equivalent and frequently superior AML colony formation and DNA synthesis. This is the first serum-free culture method for human AML that may allow for in-vitro studies of the growth regulation by recombinant growth factors under exactly defined and standardized conditions.
