Dl-3-butylphthalide-enhanced hematopoietic stem cell transplantation and endogenous stem cell mobilization for the treatment of cerebral infarcts

Exogenous stem cell transplantation and endogenous stem cell mobilization are both effective for the treatment of acute cerebral infarction. The compound dl-3-butylphthalide is known to improve microcirculation and help brain cells at the infarct loci. This experiment aimed to investigate the effects of dl-3-butylphthalide intervention based on the transplantation of hematopoietic stem cells and mobilization of endogenous stem cells in a rat model of cerebral infarction, following middle cerebral artery occlusion. Results showed that neurological function was greatly improved and infarct volume was reduced in rats with cerebral infarction. Data also showed that dl-3-butylphthalide can promote hematopoietic stem cells to transform into vascular endothelial cells and neuronal-like cells, and also enhance the therapeutic effect on cerebral infarction by hematopoietic stem cell transplantation and endogenous stem cell mobilization.
