BIOLOGICAL FACTORS AND NEURAL STEM CELLS

摘要

2148138 9410292 PCTABS00032 Methods are described for increasing the number of neural stem cells that differentiate into astrocytes, oligodendrocytes, or neurons. The methods comprise proliferating isolated neural stem cells in a culture medium having a first growth factor to produce precursor cells. The precursor cells are then differentiated into astrocytes, oligodendrocytes, or neurons in a second culture medium, free of the first growth factor, containing a second growth factor or combination of growth factors.
