Abstract:
Objective To study the effects of bone marrow stromal cells derived neural stem cells on apoptosis and the expression of Bcl-2 and Bax after focal cerebral ischemia and reperfusion.Methods The model of middle cerebral artery occlusion (MCAO) and reperfusion was set up by Longa. Thirty-two Sprague-Dawley rats were divided into 4 groups: sham-operated group (A), ischemia control group (B), bone marrow stromal cells transplanted group (C) and bone marrow stromal cells derived neural stem cells transplanted group (D). The rats were killed on the day 7 and 14 after transplantation. The brain sections were used for terminal deoxynucleotidyl transferase dUTP mickend labeling (TUNEL) staining and Bcl-2, Bax immunohistochemical staining.Results The number of apoptotic cells in groups C and D was decreased as compared with that in group B on the day 7 and 14 after transplantation (P
