【Abstract】 Starting from the definition of stem cells, research and application of hematopoietic and neuronal stem cells, the present review comments on the key problems from stem cell research with emphasis on proliferation and identification of stem cells, Plasticity and pleuripotency of stem cells, the significance of stem cells in tissue repair and development. The present trend of studying stem cells at molecular level was stressed. The elucidation of the underlying mechanism of stem cell proliferation, differentiation and trans differentiation would help in their modification to improve and expand their clinical application.更多还原
