Fig. 6From: Nanoscale perfluorocarbon expediates bone fracture healing through selectively activating osteoblastic differentiation and functionsALP determination of MG-63 cell-derived osteoblasts with or without nano-PFC treatment. a Representative images of ALP staining after nano-PFC treatment at different concentrations for 7 days. Blue arrowheads indicate positive ALP staining in mature osteoblasts. The scale bar is 100 μm. b Quantified data of ALP staining. #P < 0.001, compared with the control groupBack to article page
