Fig. 1From: Klotho enhances bone regenerative function of hPDLSCs via modulating immunoregulatory function and cell autophagyEffect of Klotho pretreatment on hPDLSC survival at the transplantation site. A Immunofluorescence images of total Caspace-3 and c-Caspase-3 expression in hPDLSCs. B Immunofluorescence images of proliferating hPDLSCs (green and red overlap). C Immunofluorescence images of apoptotic hPDLSCs (green and red overlap). D HNA-positive, Ki67/HNA and C-caspase-3/HNA double-positive cell rates (%) in each group. Scale bar = 50 µm (A) and 20 µm (B, C). *P < 0.05, **P < 0.01Back to article page
