Figure Lengend Snippet: a CSF1 expression with Hoechst 33342 and their merges of testicular sections from mice under four different treatments in the short term (W2, 2 weeks) and long term (W8, 8 weeks) experiments. Scale bar, 200 μm. b ELISA of CSF1 in mice serum of the four different groups in W2 and W8 experiments. c RT-qPCR detected Csf1 expression in mice testicular tissue under the four different treatments in W2 and W8 experiments. d CSF1 expression level detected by western blot analysis in the four groups in W2 and W8. Histograms are the statistical result of Image J (V1.48d) gradation analysis for the western blot experiments. (The results are shown as the mean ± S.E.M of at least three mice ( n = 3) and the statistical significance was expressed as follows: * p < 0.05; ** p < 0.01). C control group, M normal group treated with MLT, D diabetic group, DM MLT-treated diabetic group

Figure Lengend Snippet: a CSF1 expression with Hoechst 33342 and their merges of MLTC-1 under three different ERS states (C control, Tm Tm treatment induced excessive ERS, Tm + 4PBA Tm treatment in combination with 4PBA for alleviated ERS). b CSF1 concentration in culture medium of MLTC-1 under the three different treatments was detected using ELISA. c RT-qPCR detected the mRNA expression level of Csf1 in MLTC-1 under the three treatments. d Expression of CSF1 in MLTC-1 under different treatments was measured by Western blot. Histograms are the statistical result of Image J (V1.48d) gradation analysis for the western blot experiments. e A graphical conclusion of this study is displayed: DM-induced high glucose activated ERS response factors (Grp78 and CHOP) in Leydig cells, resulting in apoptosis of Leydig cells and growth arrest of SSCs in testes. In response to these changes, melatonin treatment alleviated the apoptosis of Leydig cells via inhibition of ERS and recovered the CSF1 secretion in testes. CSF1 then resumed the self-renewal capacity of SSCs. (The results are expressed as the mean ± S.E.M of three separated wells of cells ( n = 3) in at least three different experiments and the statistical significance is expressed as follows: * p < 0.05; ** p < 0.01)
