...Wichterle et al. (2002) were the first to derive a protocol for the directed differentiation of ESCs to a specific neural type, using induction with retinoic acid and a sonic hedgehog analog to induce transplantable murine spinal motor neurons (Wichterle et al., 2002)....

...Studies of the neurogenic potential of progenitor cells have focused on three major classes of cells: neural progenitors derived from embryonic or adult nervous tissue (Alvarez-Buylla et al., 2001; Gage, 2000; Uchida et al., 2000), nonneural progenitor cells derived from other tissues and organs (Brazelton et al....
