Lateral ventricle administration of BMSC-exos promoted neuron regeneration and the expression of BDNF in the hippocampus of mice injected with STZ. A Fluorescence detection of the hippocampal neonatal neuron marker DCX; B Statistics of the number of DCX positive cells and the quantification of the pixels of DCX positive area. C Western blot photos of Syt-1, Synapsin-1 and BDNF; D Quantification of Syt-1, Synapsin-1 and BDNF expression levels. Data are presented as means ± SEM, with n = 3 in each group (*P < 0.05, **P < 0.01)
