Abstract: The invention discloses a family of peptides termed NRP compounds or NRPs that can promote neuronal migration, neurite outgrowth, neuronal proliferation, neural differentiation and/or neuronal survival, and provides compositions and methods for the use of NRPs in the treatment of brain injury and neurodegenerative disease. NRP compounds can induce neurons and neuroblasts to proliferate and migrate into areas of damage caused by acute brain injury or chronic neurodegenerative disease, such as exposure to toxins, stroke, trauma, nervous system infections, demyelinating diseases, dementias, and metabolic disorders. NRP compounds may be administered directly to a subject or to a subject's cells by a variety of means including orally, intraperitoneally, intravascularly, and directly into the nervous system of a patient. NRP compounds can be formulated into pharmaceutically acceptable dose forms for therapeutic use.

Abstract: The present invention is directed to the use of choroids plexus cells and/or choroids plexus conditioned media for enhancing the growth, survival and/or maintenance of function of non-choroid plexus cells grown in long term or short term culture.
