From: Human fetal mesenchymal stem cell secretome enhances bone consolidation in distraction osteogenesis
Human fetal mesenchymal stem cell (hFMSC) secretome promoted osteogenic differentiation of rBMSCs in vitro. The alkaline phosphatase (ALP) staining was conducted after 3 days of treatment with secretome with different doses in OIM, and the Alizarin Red S staining and its quantitated measurement were performed after 7 and 14 days administration of secretome. Significantly more mineralization was seen in the hFMSC secretome group with a dose of 100 μg/μl. **p < 0.01. d day, OD optical density
