Every cell obtains its DNA from either a single parent cell or two parent cells depending upon method of reproduction. Because organs are specialized cell types, it follows that an organ once removed maintains the DNA of the host the organ came from direct virtue- e.g. organ cells are of a specialized type hence only heart cells can reproduce to create heart cells, etc. he plausible exception: the stem cell, but this would take a rather long time and would require that the organ have reproduced every cell composing it at least once, and that assumes that stem cells are plentiful enough as to fashion the kind of counts needed, which apart from neonates, they are not as the rule.
