Aims: To compare the effects of polypropylene mesh or porcine dermal acellular collagen matrix mesh with and without estradiol supplementation on vaginal smooth muscle cells (VaSMC) proliferation. Results: Under in vitro culture conditions, VaSMC proliferation was significantly higher in the porcine dermal acellular collagen matrix mesh exposed cells compared to the type I polypropylene mesh exposed cells (relative cell number, mean +/- SD, 0.27 +/- 0.03 vs. 0.21 +/- 0.01, P 0.03). Under estradiol supplementation cell proliferation in the porcine mesh exposed cells remained significantly higher compared to the polypropylene mesh exposed cells (relative cell number, mean +/- SD, 0.27 +/- 0.04 vs. 0.15 +/- 0.03, P < 0.01). Conclusion: Thedecreasedrate of erosionfoundwiththe utilization of biological absorbablemesh in vaginal reconstructive surgery may partially be explained by the significantly increased VaSMC proliferation with porcine dermal acellular collagen mesh compared to polypropylene mesh.
