Abstract

Stroke can cause permanent neurological damage, complications, and even death. However, there is no treatment exists to restore its lost function. Human embryonic stems transplantation therapy was a novel and potential therapeutic approach for stroke. However, as we have seen, the ethical controversy pertains to embryonic stem cell research. Human induced pluripotent stem cells (iPSCs) are the latest generation of stem cells that may be a solution to the controversy of using embryonic cells. In our study, we generated iPSCs from adult human fibroblasts by introduction of four defined transcription factors (Oct4, Sox2, Nanog, and Lin-28). And then, we investigated the efficacy of iPSCs transplantation therapy for stroke on the animal models of middle cerebral artery occlusion. Surprisingly, we found that transplanted iPSCs migrated to injured brain areas, and differentiated into neuron-like cells successfully. After 4-16 days iPSCs grafting, sensorimotor function of rats has been improved significantly. In one word, we may prove that iPSCs therapy in stroke to be an effective form of treatment.
