Effect of growth hormone and igf-1 on neural stem cells and therapeutic application

摘要

The present invention provides a method of increasing neural stem cell numbers by using growth hormone and/or IGF-1. The method can be practiced in vivo to obtain more neural stem cells in situ, which can in turn produce more neurons or glial cells to compensate for lost or dysfunctional neural cells. The method can also be practiced in vitro to produce a large number of neural stem cells in culture. The cultured stem cells can be used, for example, for transplantation treatment of patients or animals suffering from neurodegenerative diseases or conditions.
