Background. The loss of interstitial cells of Cajal (ICC) is observed in diabetic gastroparesis. Electroacupuncture (EA) maintains ICC networks, but the effects and mechanisms of EA on ICC of bone marrow derivation in the stomach have not been investigated. Methods. C57BL/6 mice were randomized into six groups: control, diabetic (DM), bone marrow transplantation (BMT) + DM, BMT + DM + sham EA (SEA), BMT + DM + low-frequency EA (LEA), and BMT + DM + high-frequency (HEA). c-Kit+GFP+ cells in the stomach were detected by immunofluorescence staining. Western blotting and qRT-PCR were employed to determine c-Kit, GFP, SDF-1, CXCR4, mSCF, pERK, and ETV1 expression. Results. (1) c-Kit+GFP+ cells were elevated in the BMT + DM + LEA and HEA groups. (2) The mRNA and protein levels of GFP, SDF-1, and CXCR4 were increased in the BMT + DM + LEA and BMT + DM + HEA groups. (3) The mRNA and protein levels of mSCF, c-Kit, pERK, and ETV1 were significantly reduced in the DM group but markedly elevated in the BMT + DM + LEA and HEA groups. Conclusion. EA at ST36 increases bone marrow-derived ICC in the stomach of diabetic mice via the SDF-1/CXCR4 and mSCF/c-Kit-ETV1 pathways.

Cells Of Cajal

Interstitial cells of Cajal (ICCs) in gastrointestinal tract are specialized cells serving as pacemaker cells. The origin of ICCs is currently not fully characterized. In this work, we aimed to study whether bone marrow-derived cells (BMDCs) could contribute to the origin of ICCs in the muscular plexus of small intestine using GFP-C57BL/6 chimeric mice.Engraftment of BMDCs in the intestine was investigated for GFP expression. GFP positive bone marrow mononuclear cells reached a proportion of95.65%±3.72%at different times in chimerism. Donor-derived cells distributed widely in all the layers of the gastrointestinal tract. There were GFP positive BMDCs in the myenteric plexus, which resembled characteristics of ICCs, including myenteric location, c-Kit positive staining, and ramified morphology. Donor-derived ICCs in the myenteric plexus contributed to a percentage ranging9.25%±4.9%of all the ICCs in the myenteric plexus. In conclusion, here we described that donor-derived BMDCs might differentiate into gastrointestinal ICCs after radiation injury, which provided an alternative source for the origin of the ICCs in the muscular plexus of adult intestine. These results further identified the plasticity of BMDCs and indicated therapeutic implications of BMDCs for the gastrointestinal dysmotility caused by ICCs disorders.
