Cholinergic Nerve Differentiation of Mesenchymal Stem Cells Derived from Long-Term Cryopreserved Human Dental Pulp In Vitro and Analysis of Their Motor Nerve Regeneration Potential In Vivo.

ABSTRACT: The reduction of choline acetyltransferase, caused by the loss of cholinergic neurons, leads to the absence of acetylcholine (Ach), which is related to motor nerve degeneration. The aims of the present study were to evaluate the in vitro cholinergic nerve differentiation potential of mesenchymal stem cells from cryopreserved human dental pulp (hDPSCs-cryo) and to analyze the scale of in vivo motor nerve regeneration. The hDPSCs-cryo were isolated and cultured from cryopreserved dental pulp tissues, and thereafter differentiated into cholinergic neurons using tricyclodecane-9-yl-xanthogenate (D609). Differentiated cholinergic neurons (DF-chN) were transplanted into rats to address sciatic nerve defects, and the scale of in vivo motor nerve regeneration was analyzed. During in vitro differen
