Any references made to such things as "DNA" and/or "fingerprints" really does not apply to either type in their true and pure forms. It isn't DNA variations per se, but surface antigens, often referred to as "markers", that signal "self" from "other". "Self" being the bodies own matter and "other" being a foreign substance. The consensus of studies published in scientific literature is that human umbilical cord stem cells (hUCSCs) provoke little in the way of adverse reactions due to antigenic recognition by the recipient. Meaning that because they lack markers the body sees them as "self". This is why antirejection medication is not needed when doing a SCT with hUCSCs in the manner that is done by Beike.
