The capacity of human adipose-derived stem cells (hADSCs) to differentiate into motor neurons and the identity of molecular factors that confer hADSCs with the competence of motor neurons have yet to be elucidated. Here, retinoic acid and sonic hedgehog were applied to examine whether hADSCs could be differentiated into motor neurons. As early as 6 h after induction, hADSCs were changed toward neuronal morphology. After induction, hADSCs showed positive immunocytochemical staining for beta-III-tubulin, choline acetyltransferase, and neuron-specific enolase. Reverse-transcriptase polymerase chain reaction characterization indicated that cells differentiated from hADSCs were restricted to the ventral spinal fate (Nkx2.2, Pax6, Hb9, and Olig2). Our results suggest that hADSCs may be a potential candidate in cellular therapy for motor neuron disease. NeuroReport 22:370-373 (C) 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.
