Rat Neural Stem Cells (RNSC) are isolated from cerebral striatum and mesencephalon of E18 fetal or adult rat brains. These cells were maintained in undifferentiated proliferative state by culturing them as free floating neurospheres in serum-free medium optimized with growth factors. They are cryopreserved at first passage and can be cultured and propagated for 1-2 passages1 prior to induction of phenotypic differentiation. These stem cells are multipotent2,3 and can be induced to differentiate into neurons, astrocytes and oligodendrocytes that make up the central nervous system (CNS). Neurospheres transplanted into intact brain can survive, expand and differentiate into mature neurons, astrocytes and oligodendrocytes precursors4 in 3 weeks. The ability of neural stem cells to retain multi-lineage potential and proliferate extensively in vitro provides new avenues for the treatment of neural degenerative diseases and injuries.
