Abstract (original English)
This study aimed to evaluate the use of Insulin-Transferrin-Selenium (ITS) medium in place of fetal bovine serum (FBS) to culture human amnion mesenchymal stem cells (hAMSCs). Cell morphology, ultrastructure, proliferation, migration and MSC related markers were assessed accordingly. The hAMSCs were induced to osteocyte, chondrocyte, adipocyte and keratinocyte by culturing in appropriate induction medium. hAMSCs mRNA expression was detected for the matrix metalloproteinases 2 (MMP2), keratinocyte growth factor (KGF), vascular endothelial growth factor (VEGF), insulin-like growth factor-I (IGF-I), Platelet-derived Growth Factor (PDGF), and transforming growth factor beta 1 (TGF-β) by real-time quantitative RT-PCR. Our results showed that hAMSCs cultured in ITS medium exhibited similar proliferation rates, demonstrated a statistically significant increased migration and expressed similar levels of MSC markers(CD73+, CD90+, CD105+, CD45-, CD34-) compared with those cultured in FBS. Osteoblasts, chondrocytes, adipocytes and keratinocytes were differentiated. Results of transmission electron microscope (TEM) revealed that hAMSCs cultured in ITS medium underwent active metabolism. The mRNA expression of MMP2, VEGF, KGF, TGF-β, IGF-I and PDGF upregulated in ITS medium. In conclusion, ITS medium has the potential to be used for the expansion of hAMSCs before clinical application.
