dc.description.abstractBoth keratinocyte transplantation and epidermal growth factor (EGF) delivery stimulate epidermal regeneration. In this study, we hypothesized that the combined therapy of keratinocyte transplantation and EGF delivery accelerates epidermal regeneration compared to the single therapy of either keratinocyte transplantation or EGF delivery. To test this hypothesis, we utilized fibrin matrix as a keratinocyte/EGF delivery vehicle for epidermal regeneration. Full-thickness wounds were created on the dorsum of athymic mice, and human keratinocytes and EGF in fibrin matrix were sprayed onto the Wounds to regenerate epidermal layers (group 1). As controls, human keratinocytes in fibrin matrix (group 2), EGF in fibrin matrix (group 3), or fibrin matrix alone (group 4) was sprayed onto the wounds. Spraying keratinocytes suspended in fibrin matrix did not affect the keratinocyte viability, as the cell viabilities before and after spraying were not different. EGF was released from fibrin matrix for 3 days. The wounds were analyzed with histology and immunohistochemistry at 1 and 3 weeks after treatments. Compared with the control groups. initial Wound closure rate was highest in group 1. Histological analyses indicated that group 1 exhibited faster and better epidermal regeneration than the other groups. Immunohistochemical analyses showed that regenerated epithelium in groups 1 and 2 stained positively for human involucrin at 3 weeks, whereas the tissue sections of the groups 3 and 4 stained negatively. Human laminin was detected at the dermal-epidermal junction of the regenerated tissues in groups 1 and 2 at 3 weeks and was not detected in groups 3 and 4. The epidermal thickness of the regenerated tissues in group I was significantly thicker than that of the other groups at all time points. These results suggest that the combined therapy of keratinocyte transplantation and EGF delivery is more efficacious for epidermal regeneration than each separate therapy alone.-
