We have previously shown that human parthenogenetic stem cells (hpSC) can be chemically directed to differentiate into a homogeneous population of multipotent neural stem cells (hpNSC) that are scalable, cryopreservable, express all the appropriate neural markers, and can be further differentiated into functional dopaminergic neurons. Differentiation of hpSC into hpNSC provides a platform to study the molecular basis of human neural differentiation, to develop cell culture models of neural disease, and to provide neural stem cells for the treatment of neurodegenerative diseases. Additionally, the hpNSC that are generated could serve as a platform for drug discovery and the determination of pharmaceutical-induced neural toxicity. Here, we describe in detail the stepwise protocol that was developed in our laboratory that facilitates the highly efficient and reproducible differentiation of hpSC into hpNSC.
