Abstract

Abstract: Stem cell therapies have made strides toward the efficacious treatment of injured endometrium and the prevention of intrauterine adhesions, or Asherman's syndrome (AS). Despite this progress, they are limited by their risk of tumor formation, low engraftment rates, as well as storage and transportation logistics. While attempts have been made to curb these issues, there remains a need for simple and effective solutions. A growing body of evidence supports the theory that delivering media, conditioned with mesenchymal stem cells, might be a promising alternative to live cell therapy. Mesenchymal stem cell‐secretome (MSC‐Sec) has a superior safety profile and can be stored without losing its regenerative properties. It is versatile enough to be added to a number of delivery vehicles that improve engraftment and control the release of the therapeutic. Thus, it holds great potential for the treatment of AS. Here, a new strategy for loading crosslinked hyaluronic acid gel (HA gel) with MSC‐Sec is reported. The HA gel/MSC‐Sec treatment paradigm creates a sustained release system that repairs endometrial injury in rats and promotes viable pregnancy. Abstract : Mesenchymal stem cell‐secretome‐loaded, crosslinked hyaluronic acid gel demonstrates therapeutic efficiency for Asherman's syndrome in a rat model. This strategy can bypass the risks associated with stem cell therapies, but also construct an intrauterine sustained release system to repair endometrial injury and improve pregnancy rate.
