Various types of skin substitutes composed of fibroblasts and/or keratinocytes have been used for the treatment of diabetic ulcers. However, the effects have generally not been very dramatic. Recently, human umbilical cord blood‐derived mesenchymal stromal cells (hUCB‐MSCs) have been commercialised for cartilage repair as a first cell therapy product using allogeneic stem cells. In a previous pilot study, we reported that hUCB‐MSCs have a superior wound‐healing capability compared with fibroblasts. The present study was designed to compare the treatment effect of hUCB‐MSCs with that of fibroblasts on the diabetic wound healing in vitro. Diabetic fibroblasts were cocultured with healthy fibroblasts or hUCB‐MSCs. Five groups were evaluated: group I, diabetic fibroblasts without coculture; groups II and III, diabetic fibroblasts cocultured with healthy fibroblasts or hUCB‐MSCs; and groups IV and V, no cell cocultured with healthy fibroblasts or hUCB‐MSCs. After a 3‐day incubation, cell proliferation, collagen synthesis levels and glycosaminoglycan levels, which are the major contributing factors in wound healing, were measured. As a result, a hUCB‐MSC‐treated group showed higher cell proliferation, collagen synthesis and glycosaminoglycan level than a fibroblast‐treated group. In particular, there were significant statistical differences in collagen synthesis and glycosaminoglycan levels ( P = 0·029 and P = 0·019, respectively). In conclusion, these results demonstrate that hUCB‐MSCs may have a superior effect to fibroblasts in stimulating diabetic wound healing.
