Stem cell DNA, that is introduced into you or anyone else, does not interfere with your DNA. Assume the stem cells are the orchestra conductor and when introduced locally in the tissues or in the IV, the stem cells just tell your body’s cells what to do. Another analogy is to assume that the stem cells are running the first arm of a relay and they pass the baton off to your cells telling them what to do. Millions of stem cell procedures have been done, and to date, there is no evidence that stem cell DNA interacts, changes, or alters the host’s DNA. Also, they are gone from the body in about 1 month, i.e., after the race is over, or the concert has ended the stem cells’ work is done and your body continues to do the necessary repair.  In addition, prior to use, the stem cells are tested and do not react with your blood, or any other component to cause rejection. Also, they test for COVID antibodies and reject any and all positive stem cells.
