Abstract

The current urogynecological clinical meshes trigger unfavorable foreign body response which leads to graft failure in the long term. To overcome the present challenge, we applied a tissue engineering strategy using endometrial SUSD2+ mesenchymal stem cells (eMSCs) with high regenerative properties. This study delves deeper into foreign body response to SUSD2+ eMSC based degradable PLACL/gelatin nanofiber meshes using a mouse model targeted at understanding immunomodulation and mesh integration in the long term. Delivery of cells with nanofiber mesh provides a unique topography that enables entrapment of therapeutic cells for up to 6 weeks that promotes substantial cellular infiltration of host anti-inflammatory macrophages. As a result, degradation rate and tissue integration are highly impacted by eMSCs, revealing an unexpected level of implant integration over 6 weeks in vivo. From a clinical perspective, such immunomodulation may aid in overcoming the current challenges and provide an alternative to an unmet women's urogynecological health need.
