Fig. 1From: Novel transplant of combined platelet-rich fibrin Releasate and bone marrow stem cells prevent bone loss in Ovariectomized osteoporotic miceCell morphology, surface marker expressions and osteogenic differentiation potential of bone marrow stem cells (BMSCs). a Colony forming unit is shown under bright field observation in the passage 0 BMSC culture. b For flow cytometry analysis, the BMSCs were found to exhibit a phenotype of CD44+ CD90+ CD34- CD45-. c Alizarin Red S (ARS) staining of BMSCs cultured in standard medium (upper panel) or osteogenic differentiation medium (lower panel) for 14 days. d Quantitation of ARS staining intensity. Scale bar- 100 μm. The bars show the mean ± SD (n = 3) of each group. **P < .01Back to article page
