Abstract:
Objective To study the ultrastructure of neural stem cell neurosphere cultured in vitro. Methods Neural stem cell neurospheres from the rat brain were observed under transmission electron microscope or with stain of lanthanum nitrate, ruthenium red and tannic acid. Results The conjunction between the cells within neurosphere was loose and no tight junction was observed. Neural stem cells were proliferating lively. Some neural stem cells differentiated into cells with process and structure of axon, even showed the structures similar to myelin.Conclusion The ultrastructure of neural stem cell neurosphere cultured in vitro was revealed.
