The purpose of this study was to investigate the ability of human BM-MSCs and AT-MSCs to survive, proliferate and deposit collagen type 1 when cultured on polycaprolactone nanofiber scaffolds and to ascertain the effect of medium composition on collagen type 1 formation and expression of osteogenic genes. The cells were seeded on polycaprolactone nanofiber scaffolds and cultured in three different types of media that differed by the presence of ascorbic acid,beta-glycerophosphate and dexamethasone, that are typical components used for osteogenic differentiation of MSCs in vitro.
In summary, AT-MSCs were proliferating significantly faster than BM-MSCs. AT-MSCs also showed better ability to deposit collagen type 1 and had a higher expression of early osteogenic markers, whereas BM-MSCs had higher expression of late osteogenic markers. This suggests that MSCs from diverse sources have different attributes and with respect to osteogenic differentiation, AT-MSCs are more immature compared to BM-MSCs. Collagen formation was depending on medium composition and the organization of collagen type I appeared to be influenced by the presence of dexamethasone.Pracoviště Ústav experimentální medicíny Kontakt Lenka Koželská, lenka.kozelska@iem.cas.cz, Tel.: 241 062 218, 296 442 218 Rok sběru 2018
