The National Institutes of Health clinical trials registry clinicaltrials.gov provides information on treatments and therapies being tested for specific diseases or health conditions. Not every trial is registered, but this site offers the most comprehensive listing; of tens of thousands of publicly and privately funded trials in virtually any corner of the globe. The site summarizes each trial, including its status (whether it’s still recruiting patients), location, and participant criteria. The FAQ page provides a full explanation on what clinical trials are, how they work, and information on signing up for trials.
Just type “stem cells” into the search box to find all the registered clinical trials involving stem cells. Then use the data from this site to search the Internet for more detailed descriptions of the trials.
