Assessment of bovine adipose-derived stem cells osteogenic and adipogenic differentiation in Normoxic and hypoxic conditions
Abstract
Background: The differentiation of ADSC is regulated by many factors, including oxygen tensions. Evidences have suggested that low oxygen tension or hypoxia is involved in the osteogenic, adipogenic differentiations of MSCs. Expansion and induction of ADSCs under hypoxia generally result in enhanced osteogenic, differentiation. Therefore, we analyzed bovine ADSC differentiations in Normoxia and hypoxia conditions
Methodology: Recently (<8h) cow tail from a slaughterhouse, take out some fat from the tail and fat cells was isolated by using for isolation of ADSC protocol, the expansion cells were put into osteogenic and adipogenic medium for 3 weeks in hypoxia and normoxia conditions separately and characterized by Von kossa, Alizarin red and Oil red O staining and further by using real-time PCR by using primers of osteocalcin, Collagen type1, cbfa1/runx2, ALP, ostepontin, osteonectin, BMP2, BMP24, BMP27, noggin, gremlin, Nestin and HIF1A,VEGFA,PPARG,Leptin.
Results: Our experiment results show hypoxia promotes osteogenesis but suppresses adipogenesis.
