Research Abstract |
Recent studies have shown that transplantation of neural crest cells (NCCs) is effective on spinal cord injury. Here we used NCCs from aged mouse iPS cells for treatment of diabetic polyneuropathy. iPS cells were differentiated on PA6 cells with BMP4 , and p75 positive cells were defined as NCCs. NCCs were transplanted into hind limb skeletal muscles of STZ-diabetic mice. Transplanted NCCs differentiated into vascular smooth muscle cells or Schwann cells in plantar skin or soleus muscle. Impaired nerve functions in diabetic mice were ameliorated by the transplantation of NCCs. In addition, transplantation of NCCs increased intraepidermal nerve fiber densities, plantar skin blood flow and capillaries in DM. These results suggest that transplantation of NCCs derived from iPS cells could have therapeutic effects on DPN through paracrine actions of growth factors secreted by NCCs and differentiation of NCCs into Schwann cells and vascular smooth muscle cells.
