Figure 5From: Overexpression of Bcl-2 promotes survival and differentiation of neuroepithelial stem cells after transplantation into rat aganglionic colonNeuroepithelial stem cells offer enteric nervous system appropriate differentiation upon grafting into recipient aganglionic gut. Evidence of 4',6-diamidino-2-phenylindole (DAPI)-labeled neuroepithelial stem cell graft (shown in blue) differentiation into neuronal nitric oxide synthase (nNOS; shown in green) and choline acetyltransferase (shown in red) neuronal subtypes was apparent at 8 weeks post transplantation in the (A) control group and (B) Bcl-2 group. LM, longitudinal muscle; CM, circular muscle. Scale bar = 200 μm. (C) Ratio of nNOS-positive cells versus DAPI-labeled cells was counted. Bcl-2 overexpression increased the ratio of nNOS-positive cells. *Significant difference compared with control group (P < 0.05, n = 6 for each group).Back to article page
