Figure Lengend Snippet: Coculturing with BMSCs promotes better cell morphology and fewer apoptotic cells. (A) Culturing in hypoxic conditions reduced the cell viability of 661w cells, which could be rescued by coculturing with BMSCs, although slightly lower than that of normal cells. (B) Red fluorescence indicated JC‐1 in normal cells with a normal Δ Ψm, while green fluorescence indicated a low Δ Ψm in hypoxic cells. Magnification: 20×. (C) Coculture with BMSCs decreased the apoptosis and necrosis in 661w cells undergoing hypoxia. These assays were repeated for three times. *: P < .05, compared with hypoxic cells. #: P < .05, compared with normal cells

Figure Lengend Snippet: Coculturing with BMSCs increased autophagy in 661w cells, and the effect of BMSCs was weakened when autophagy was inhibited. (A) MDC staining showed higher number of autophagosome in hypoxic cells, as compared to normal cells, and the autophagosome was further increased in the cocultured group. Magnification: 20×. (B) In the cocultured group, the expression of LC3II and the ratio of LC3II/LC3I were obviously increased, while the expression of p62 was decreased, compared with those in the hypoxia and normal groups. (C) 3‐MA, an autophagy inhibitor strongly diminished the protective effects of BMSCs. In the autophagy‐inhibited coculture (inhibited) group, the cell viability was decreased to nearly that in the hypoxia group. These assays were repeated for three times. *: P < .05, compared with the other two groups. #: P < .05, compared with cocultured cells

Figure Lengend Snippet: BMSC transplantation attenuated apoptosis and activated autophagy in photoreceptors in retinal detachment. (A) TUNEL staining showed that the subretinal transplantation of BMSCs significantly reduced the number of TUNEL‐positive cells in the ONL at 3 (cells/mm 2 , P < .05) and 7 d (cells/mm 2 , P < .05) after treatment compared to those in the blank and NC groups. Magnification: 40×. (B and C) At 3 d after transplantation, the treated group showed significantly lower cleaved caspase‐3 levels than the other two groups ( P < .05), and at 1 wk after transplantation, this level decreased to nearly that in the normal retina. Significant differences in caspase‐8 and cleaved caspase‐9 levels were also found between retinas treated with BMSCs and the other two groups. (D) The expression of the microtubule‐associated protein LC3‐II was decreased, and p62 expression was increased at 6 and 10 d after RD compared with those at 3 d after RD, suggesting that autophagy levels peaks on day 3 after RD. Three days after treatment, significantly increased LC3‐II expression and decreased p62 levels were found in the BMSC‐treated group compared to those in the other two groups. However, after 7 d post‐treatment, the levels did not differ significantly among the groups. These assays were repeated for three times

(B-D) RT-PCR analysis quantifying the mRNA levels of osteogenic markers runx2 , bmp2 , ocn , opn and opg in BMSCs co-cultured with conditional medium at 4 (B) , 7 (C) and 14 (D) days (n = 3). (E) Representative images of ALP staining of BMSCs cultured in conditional medium for 14 days. Scale bar = 500 μm. (F) Quantitative analysis of ALP activity of BMSCs cultured in conditional medium for 14 days (n = 3). (G) Representative images of ARS staining of BMSCs cultured in conditional medium for 21 days. Scale bar = 500 μm. (H) Quantitative analysis of ARS staining in BMSCs (n = 3). Data are presented as the mean ± SD from at least three independent experiments. P values were calculated using two-tailed Student’s t test; * P < 0.05, ** P < 0.01, *** P < 0.001.
