Fig. 7From: Transplantation of dental pulp stem cells improves long-term diabetic polyneuropathy together with improvement of nerve morphometrical evaluationDental pulp stem cell-conditioned media (DPSC-CM) promoted Schwann cell viability and myelin formation. a The effects of DPSC-CM on Schwann cell viability were measured by CCK-8 analysis. The results are means ± SEM. *P < 0.05, **P < 0.01; n = 12. b The protein expression of myelin protein zero (MP0), a related protein for the myelination of Schwann cells, was assessed after a 5-day incubation with DPSC-CM by Western blotting. c Microscopic analysis of MP0-positive myelin segments in Schwann cells treated with DPSC-CM further revealed the expression of MP0 compared with that in the controlBack to article page
