“…Adverse events have also been reported along with the rise of the stem cell clinic industry [9], but it is presently unknown if these are increasing in incidence, at least in part because some firms fail to voluntarily track and accurately report negative outcomes. There is nonetheless the perception that adverse events are increasing in number at least in part driven by numerous recent cases of infections from unproven stem cell infusions [10,11]. Variable quality of stem cell production laboratories is likely a factor increasing the risk of adverse events, but so too is the unfortunate reality that many of those administering stem cells to patients are not even physicians or if they are physicians they frequently are practicing outside of their areas of expertise [12,13].…”

Aim: The industry of unproven stem cell clinics has rapidly mushroomed throughout the USA, posing risks to patients and the research field. In this study, the aim was to better define how this industry changes. Methods: I analyzed a large cohort of US stem cell clinic firms and their distinct clinic locations as defined in 2015–2016 for their status now in 2019. Results: About a quarter of the firms no longer marketed stem cells. Some lacked active websites, while others dropped stem cell services. Even so, the total number of clinics in this group increased because some firms greatly expanded their clinic numbers. Conclusion: Overall, the unproven clinic industry is a moving target requiring ongoing study and regulatory oversight.
