Abstract
To find a promising alternative to neurons or schwann cells SCs for peripheral nerve repair applications this study sought to isolate stem cells from fetal rat dorsal root ganglion DRG explants Molecular expression analysis confirmed neural stem cell characteristics of DRGderived neurospheres in terms of expressing neural stem cellspecific genes and a set of welldefined genes related to stem cell niches and glial fate decision Under the influence of neurotrophic factors bFGF and NGF the neurospheres gave rise to neurofilamentexpressing neurons and S100expressing Schwann celllike cells by different pathways This study suggests that a subpopulation of stem cells that reside in DRGs is the progenitor of neurons and glia which could directly induce the differentiation toward neurons or SCs
