Abstract:
Objective To investigate the effect of bone marrow mesenchymal stem cells(BMSC)transplantation on rats with painful diabetes peripheral neuropathy(PDPN).Methods Fourteen SPF grade male GK rats were randomly divided into model group and treat-ment group,with 7 rats in each group.Seven Wistar rats of the same-sex and same-age were used as the normal group.The treatment group received intraperitoneal injection of BMSC for 6 weeks of treatment.Detection of thermal pain threshold;take the sciatic nerve and observe the pathological morphological changes of the sciatic nerve using hematoxylin-eosin(HE)staining and Masson staining;Western blot was used to detect the expression of JAK2/STAT3 signaling pathway related proteins p-JAK2 and p-STAT3.Results After treat-ment with BMSC,the thermal pain threshold of rats increased slightly;the sciatic nerve injury was repaired,the infiltration of inflammato-ry cells was alleviated,and the phenomenon of demyelination was improved;the expression of pathway related proteins p-JAK2 and p-STAT3 decreased.Conclusion BMSC transplantation can alleviate inflammatory response,repair sciatic nerve,and alleviate pain by in-hibiting the JAK2/STAT3 signaling pathway.
