“…Indeed, it is by merit of unique immune modulatory features, rather than differentiation, that placenta-derived MSC show promise for a wide range of regenerative medicine applications. Fast-forward to today there are over 20 clinical trials (excluding trials with unknown status) evaluating “placenta derived cells” and “placenta MSC” registered on the NIH Clinical Trials website (https://clinicaltrials.gov/) (Couto et al, 2017). The published or current clinical trials are either Phase I, II, or III and include a variety of inflammatory disorders, such as pulmonary idiopathic fibrosis (Chambers et al, 2014), peripheral artery disease, Crohn's disease (Mayer et al, 2013; Melmed et al, 2015), multiple sclerosis (Lublin et al, 2014), diabetes (Jiang et al, 2011), ischemic stroke, pulmonary sarcoidosis (Baughman et al, 2015), active rheumatoid arthritis, and muscle injury due to hip arthroplasty (Winkler et al, 2018).…”
