Fig. 3From: Transplantation of human dental pulp stem cells ameliorates diabetic polyneuropathy in streptozotocin-induced diabetic nude mice: the role of angiogenic and neurotrophic factorsSensory nerve function. The current perception thresholds (CPTs) at 5 Hz, 250 Hz, and 2000 Hz stimulated the C fiber, Aδ fiber, and Aβ fiber, respectively. The CPTs were measured with a neurometer 4 weeks after hDPSC transplantation. The CPTs for all frequencies were significantly increased in the diabetic group, and the impairments were ameliorated on the transplanted side. The results are expressed as the mean ± SD (n = 4). *P < 0.05, **P < 0.01Back to article page
