Core Tip
Core tip: Menstrual-derived stromal stem cells (MenSCs) with high proliferative capacity and self-renewal ability have a powerful therapeutic effect in patients with severe intrauterine adhesion. However, safety assessment of MenSC transplantation is essential for its further application. Here, we evaluated the short-, medium-, and long-term biosafety of MenSCs via intrauterine transplantation in an intrauterine adhesion rat model, with a special focus on toxicity and tumorigenicity. There was no acute, sub-chronic, or chronic poisoning, infection, tumor, or endometriosis in rats with intrauterine adhesions after MenSC transplantation, highlighting that intrauterine transplantation of MenSCs is safe for endometrial treatment.
