Abstract: Abstract: For the past few years， bone marrow mesenchymal stem cells have gradually become a research focus in the field of neuroscience， and have been widely used in the treatment of neurodegenerative diseases. It is just because that it can differentiate into functional neuron and express neural marker proteins successfully when inducer exists. Combined with the recent research progress， this paper will introduce the bone marrow mesenchymal stem cells from the following three aspects: firstly， the clinical trial and application of bone marrow mesenchymal stem cells; secondly， the effects of laser radiation， oxygen content and the nerve cells on the process of bone marrow mesenchymal stem cells differentiate into nerve cells; thirdly， microRNA， Notch signal pathway and Wnt signal pathway regulate the process of bone marrow mesenchymal stem cells differentiating into nerve cells.
