Abstract
Autologous dermal fibroblasts may be useful in the treatment of diabetic skin wounds. We hypothesized that cultured fibroblasts or cultured keratinocytes would not only survive in a hyperglycemic wound environment but also enhance the rate of re-epithelialization. We previously developed a new porcine model of delayed cutaneous wound healing in the diabetic pig. Full thickness wounds were created on the dorsum and dressed with polyurethane chambers to keep the wounds wet and to allow for wound fluid monitoring. Suspensions of either autologous fibroblasts or autologous keratinocytes were injected into full thickness wounds and compared with wounds treated in a wet environment in normal saline. Serum glucose and wound fluid glucose... (More)
Autologous dermal fibroblasts may be useful in the treatment of diabetic skin wounds. We hypothesized that cultured fibroblasts or cultured keratinocytes would not only survive in a hyperglycemic wound environment but also enhance the rate of re-epithelialization. We previously developed a new porcine model of delayed cutaneous wound healing in the diabetic pig. Full thickness wounds were created on the dorsum and dressed with polyurethane chambers to keep the wounds wet and to allow for wound fluid monitoring. Suspensions of either autologous fibroblasts or autologous keratinocytes were injected into full thickness wounds and compared with wounds treated in a wet environment in normal saline. Serum glucose and wound fluid glucose concentrations were monitored daily. Wound contraction was monitored and biopsies taken on day 12. Transplantation of suspensions of autologous fibroblasts or autologous keratinocytes enhanced re-epithelialization of cutaneous full thickness wounds. Wounds treated with autologous fibroblasts showed a re-epithelialization rate of 86.75% and wounds treated with autologous keratinocytes showed a re-epithelialization rate of 91.3%. This is compared with a re-epithelialization rate of 56.8% seen in the normal saline treated wounds. While previous studies have shown fibroblasts suspension to have little effect in the treatment of full thickness wounds in nondiabetic wounds, this study shows a clear beneficial effect in the use of fibroblast or keratinocyte suspensions for the cutaneous healing of diabetic wounds in pigs.
