abstract：:We have examined the regulation of adipogenesis of a 3T3-F442A cell variant. The variant, designated 3T3-GH-independent clone 16 (GI-16), was isolated after serum-induced adipogenic commitment. 3T3-GI-16 fibroblasts displayed a lower serum requirement for adipogenesis than the 3T3-F442A parent cell. Insulin-stimulated...
