adipose conversion as measured by lipid accumulation and increase in glycerophosphate dehydrogenase ( gpdh ) activity during differentiation strongly depends on the density at which cells are inoculated and starts only when cells are confluent and when physiological amounts of corticosterone and insulin are added . beta-estradiol , testosterone , thyroxine , triiodothyronine , and growth hormone do not affect the differentiation process .
