Аннотация
Intrauterine adhesions (IUA), which is characterized by endometrial fibrosis, continue to be the most common cause of uterine infertility globally. Our work revealed that 3 fibrotic progression markers (Vimentin, COL5A2, and COL1A1) were significantly increased in the endometrium of IUA patients. Mesenchymal stem cell-derived exosomes (EXOs) have been recently revealed as a cell-free therapy for fibrosis diseases. Nevertheless, the application of EXOs is restricted by the short residency duration in the target tissue. To overcome this limitation, herein, we reported an exosome-based regimen (EXOs-HP) that thermosensitive poloxamer hydrogel possessed the ability to efficiently promote the residency duration of EXOs in the uterine cavity. By downregulating fibrotic progression markers (Vimentin, COL5A2, and COL1A1), EXOs-HP could significantly restore the function and structure of the injured endometrium in the IUA model. Our work provides the theoretical and experimental foundation of EXOs-HP in treating IUA, highlighting the clinical potential of topical EXOs-HP delivery system in IUA patients.
