OBJECTIVE: To investigate whether human umbilical cord mesenchymal stem cells (UMSCs) derived exosomes (exosome) can repair the heart after myocardial infarction (MI) by delivering circ-0001273 and its mechanism. MATERIALS AND METHODS: Through the Sprague Dawley (SD) rat MI model was established, at the same time, we designed si-circ-0001273. Phosphate-buffered saline (PBS), exosome and si-circ-0001273-exosome were … Continue reading Circular RNA 0001273 in exosomes derived from human umbilical cord mesenchymal stem cells (UMSCs) in myocardial infarction
