Prevascularized Tissue-Engineered Human Vaginal Mucosa

Tissue engineering offers novel therapies for vaginal reconstruction in patients with congenital vaginal agenesis such as Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. This study aims to reconstruct a prevascularized tissue-engineered model of human vaginal mucosa (HVM) using the self-assembly approach, free of exogenous materials. In this study, a new cell culture method was used to enhance microcapillary network formation while maintaining sufficient biomechanical properties for surgical manipulation. Human vaginal fibroblasts were coseeded with human umbilical vein endothelial cells (HUVECs). Transduction of HUVEC with a vector that allows the expression of both green fluorescent protein (GFP) and luciferase allowed the monitoring of the formation of a microvascular network
