[PDF][PDF] Direct conversion of fibroblasts into stably expandable neural stem cells
Recent advances have suggested that direct induction of neural stem cells (NSCs) could
provide an alternative to derivation from somatic tissues or pluripotent cells. Here we show …

A rosette-type, self-renewing human ES cell-derived neural stem cell with potential for in vitro instruction and synaptic integration
An intriguing question in human embryonic stem cell (hESC) biology is whether these pluripotent
cells can give rise to stably expandable somatic stem cells, which are still amenable to …
