Fig. 1From: Hypoxia alleviates dexamethasone-induced inhibition of angiogenesis in cocultures of HUVECs and rBMSCs via HIF-1αHUVECs promoted MSC osteogenesis in a coculture system with OIM. MSCs were cultured in a single culture system (MSCs alone group) or a coculture system with HUVECs (coculture group). The OIM was changed every 3 days. Alizarin red S was used to detect calcium deposition on days 7, 14, and 21. Scale bar, 100 μmBack to article page
