Essential Role of Chinese Medicines in Mesenchymal Stem Cells Transplantation for Treatment of Ischemic Stroke

Ischemic stroke accounts for the majority of all strokes and has been primary causes of long-term disability and mortality in worldwide. Mesenchymal stem cell (MSC) therapy suggests significantly improved effects on neurological functional outcome, neurogenesis, angiogenesis, blood-brain barrier permeability, inflammatory injury, neuroprotection and so on, following stroke. However, the occurrence of adverse effects results in restriction of the therapy. Chinese medicine accumulates abundant clinical experiences on stroke for over two thousand years, and some formulae and active ingredients of Chinese medicines have presented obvious efficacies in clinical treatment. Therefore, based on Chinese medicine theory, we provide some ideas of screening agents for combination treatment of Chinese medicines and MSC for ischemic stroke, and summarize the potentials of Chinese medicines in MSC treatment and analyze the feasibilities of Chinese medicines against side effects of MSC therapy. Consequently, we propose Chinese medicines combing with MSC should be a promising approach to clinical stroke treatment in future.
