Background： Marrow-derived mesenchymal stem cell (MSC) is a cell source for cardiac stem cell therapy， however， those cells may not function well because of patient‘s disease background， age， and the ability of stem cell transdifferentiation that may be impaired. Placental chorionic villi are a good cell source for MSC since the young and fresh MSC can be obtained from them without any ethical problem. We hypothesized that placental chorionic villi cells (CVCs) can transdifferentiate into physiologically functioning cardiomyocyte in vitro.
