title: Growth of human foreskin fibroblasts in a serum-free, defined medium without platelet-derived growth factor.
abstract: The hormones which support growth, in vitro, of normal, neonatal human foreskin fibroblasts were determined. Whereas thrombin and hydrocortisone were major growth stimulants, platelet-derived growth factor was not. Human foreskin fibroblasts grew in a serum-free, biochemically defined medium consisting of epidermal growth factor (100 ng/ml), insulin (100 ng/ml), transferrin 10 micrograms/ml), thrombin (1 microgram/ml), ascorbic acid (10 micrograms/ml), and hydrocortisone (5 x 10(-5) M) in a 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F-12, supplemented with ovalbumin (1 mg/ml) and trace elements. The growth achieved was comparable to that achieved with 5% fetal bovine serum. Neither platelet-derived growth factor, fibroblast growth factor, nor somatomedin activity increased proliferation. This serum-free medium, designated Defined Medium F, provides a biochemically defined system for growth and limited subcultivation of human foreskin fibroblasts in vitro.
