ABSTRACT:
The present invention relates to a method of inhibiting differentiation of a population of neural stem cells by contacting a purinergic receptor agonist and a population of neural stem cells under conditions effective to inhibit differentiation of the population of neural stem cells. Another aspect of the present invention relates to a method of producing neurons and/or glial cells from a population of neural stem cells by culturing a population of neural stem cells with a purinergic receptor antagonist under conditions effective to cause the neural stem cells to differentiate into neurons and/or glial cells. The purinergic receptor agonist can also be used in a method of inducing proliferation and self-renewal of neural stem cells in a subject and a method of treating a neurological disease or neurodegenerative condition in a subject. The purinergic receptor antagonist can also be used in treating a neoplastic disease of the brain or spinal cord in a subject.
