Purpose: Acellular human dermis is very useful implant for use in plastic and reconstructive surgery. However, the volume of acellular human dermis graft is known to decrease for a long time. Basic fibroblast growth factor (bFGF) is a polypeptide that enhances the collagen synthesis and angiogenesis. In the current study we examined whether bFGF could improve the survival of acellular human dermis ($SureDerm^{(R)}$) by increasing angiogenesis of the graft. Methods: Forty rats were divided into two groups (control and bFGF). A 2-mm thick piece of $SureDerm^{(R)}$ was cut into smaller pieces that were $15{ imes}5$ mm in size. Two subcutaneous pockets were made on the back of each rat. Grafts sprayed with bFGF were implanted in the bFGF group and injected with bFGF after transplantation every 3 days for 2 weeks. In the control group, the grafts were treated with phosphate-buffered saline (PBS) instead of bFGF. Four days, and 1, 4, and 12 weeks after the implantation, the grafts were harvested and gross and histologic examinations were performed. Inflammation grade, graft thickness, neocollagen density, and neocapillary count were measured. Results: The bFGF group displayed more rapid accumulation of inflammatory cells with a higher density of neocapillaries, and increased active collagen synthesis. After 12 weeks, the thickness of the grafts in the control and bFGF groups was $75.15{pm}4.80%$ and $81.79{pm}5.72%$, respectively, in comparison to the thickness before transplantation. There was a statistically significant difference between both groups ($p$ <0.05). Conclusion: bFGF was effective in reducing the absorption of acellular human dermal grafts by increasing angiogenesis and accelerating engraftment. In conclusion, bFGF may be a good tool for use in acellular human dermal graft transplantation for reconstructive surgery involving soft-tissue defects.
