Neuroblast migration is not enhanced in mice treated with diabetic PB-MNC+. At D3 and at D14, there were no significant differences between the three groups in terms of the migration of DCX+ cells toward the ischemic area (/group). Between D3 and D14, there was a significant reduction in terms of neuroblast migration in PB-MNC+-treated mice. Data are presented as mean ± SD. . Scale bar = 200 μm.
