Fig. 6From: Transplantation of cultured dental pulp stem cells into the skeletal muscles ameliorated diabetic polyneuropathy: therapeutic plausibility of freshly isolated and cryopreserved dental pulp stem cellsMorphology and identification of cryo-DPSCs. a DPSCs, which were thawed after cryopreservation, were cultured and expanded. Cryo-DPSCs were of similar shape as the fresh-DPSCs observed with the phase contrast microscope. Bar = 100 μm. b Flow cytometric analysis of cryo-DPSCs. The expression of surface markers was analyzed with CD29, CD34, CD49d, CD45 and CD90. Open histograms, isotype controls; filled histograms, stained with the specific surface marker antibodiesBack to article page
