Abstract
Congenital vaginal anomalies and pelvic organ prolapse affect different age groups of women and both have significant negative impacts on patients' psychological well-being and quality of life. While surgical and non-surgical treatments are available for vaginal defects, their efficacy is limited, and they often result in long-term complications. Therefore, alternative treatment options are urgently needed. Fortunately, tissue-engineered scaffolds are promising new treatment modalities that provide an extracellular matrix (ECM)-like environment for vaginal cells to adhere, secrete ECM, and be remodeled by host cells. To this end, ECM-based scaffolds or the constructs that resemble ECM, generated by self-assembly, decellularization, or electrospinning techniques, have gained attention from both clinicians and researchers. These biomimetic scaffolds are highly similar to the native vaginal ECM and have great potential for clinical translation. This review article aims to discuss recent applications, challenges, and future perspectives of these scaffolds in vaginal reconstruction or repair strategies.

J Tissue Eng 2023; 14:20417314221149207. [PMID: 36726532 PMCID: PMC9885031 DOI: 10.1177/20417314221149207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 12/15/2022] [Indexed: 02/03/2023] Open
Abstract
Childbirth contributes to common pelvic floor problems requiring reconstructive surgery in postmenopausal women. Our aim was to develop a tissue-engineered vaginal wound model to investigate wound healing and the contribution of estradiol to pelvic tissue repair. Partial thickness scalpel wounds were made in tissue models based on decellularized sheep vaginal matrices cultured with primary sheep vaginal epithelial cells and fibroblasts. Models were cultured at an airliquid interface (ALI) for 3 weeks with and without estradiol-17β [E2]. Results showed that E2 significantly increased wound healing and epithelial maturation. Also, E2 led to collagen reorganization after only 14 days with collagen fibers more regularly aligned and compactly arranged Additionally, E2 significantly downregulated α-SMA expression which is involved in fibrotic tissue formation. This model allows one to investigate multiple steps in vaginal wound healing and could be a useful tool in developing therapies for improved tissue healing after reconstructive pelvic floor surgery.
