My understanding is that most cells in the human body regenerate. What I don't understand is how cells that are part of the transplant regenerate. Do they use the host or the transplanted DNA to regenerate?
- PeterisP 7y agoCells (re)generate by splitting, there's no other way. For non-mobile tissue, the tissue regenerates itself from whatever DNA the cells in that tissue have locally. There are some types of cells that are "manufactured" in one place and "shipped" throughout the body (e.g. blood cells in bone marrow) but for the transplanted tissue any new cells would still have the donor DNA forever. Also, that applies for chimeric humans that happen to have two different DNA sets from two different fertilized eggs; some parts of their body will forever have different DNA than other parts.

- PeterisP 7y agoYep, that's the correct term, English isn't my main language.
- onemoresoop 7y agoNow makes more sense. Thanks for the explaination
