Abstract (original English)
To validate the human mesenchymal stem cells (hMSCs) as a new in vitro model for the study of human adipogenesis, to develop the optimal protocol for the differentiation of hMSCs into adipocytes, and to describe effect of mitogen-activated protein kinase on hMSC differentiation into adipocytes. hMSCs, obtained commercially, were differentiated by exposure to insulin, dexamethasone, indomethacin, and 3-isobutyl-1-methylxanthine three times for 3 days each. Various differentiation conditions were examined to optimize differentiation as measured by Oil Red O staining. The gene expression during adipogenic conversion was assessed by reverse-transcription polymerase chain reaction, real-time reverse-transcription polymerase chain reaction, and Western blotting. hMSCs differentiated into adipocytes to a different extent depending on the experimental conditions. We have found that differentiation medium based on medium 199 and containing 170 nM insulin, 0.5 mM 3-isobutyl-1-methylxanthine, 0.2 mM indomethacin, 1 microM dexamethasone, and 5% fetal bovine serum was optimal. However, the replacement of fetal bovine serum with rabbit serum (15%) led to further enhancement of differentiation. Inhibition of mitogen-activated protein kinase activation also facilitated adipogenic conversion of hMSCs. The pattern of genes expressed during hMSC differentiation into adipocytes (adipsin, peroxisom
