Organ self-repair function
Most organ transplants last only 20 years or so; compared to original organs (of the person itself) which last as long as the person lives (100 years or more). I'm assuming this is due to the inability of the organ to repair itself once transplanted into a new host. This inability is I believe caused by the histocompatibility-mismatch (i.e. the body identifying the organ as foreign tissue). This histocompatibility-mismatch is adressed by various techniques (immunosuppressants, ...) so it doesn't cause any further problems (organ rejection, ...) but is NOT solved, so the organ remains seen by the body as foreign tissue. Once we succeed in actually solving the histocompatibility-mismatch (i.e. using gene therapy) won't this cause a new problem to pop-up, namely the attempting of the body to "repair" the transplanted organ ? The body has the construction DNA of its previous organ in it (the one that has been removed from the body) so will identify the newly transplanted organ as being the same and will try to use the old organ construction DNA to "repair" it. If the person has had the organ removed due to genetic defects on that organ, the body will thus try to re-implement these defects into the new organ, which is definitely not a good thing. With xenotransplants, the problem would be even worse, as organs of other animals differ significantly from their human counterparts, so the changes it would then introduce would be great, and could cause much problems.

 * Can the body's self-repair function thus be "deactivated" by altering the patients DNA using gene therapy ?
 * If the self-repair function can't be deactivated per organ (which I assume), could the entire old organ construction DNA be removed from the patient's DNA (or overwritten with the construction DNA of the newly transplanted organ) ?
 * Just to be certain, is there any data confirming that transplanted organs (where the patient uses immunosuppressants) indeed DON'T regenerate ?

Include new Israeli research in "heart" paragraph?
I am not in any way a medical professional, so I'm not sure whether to edit the paragraph on regenerating human hearts. In Israel, researchers have successfully created an entire functioning (rabbit's) heart from stem cells and a 3D-printed scaffolding. Said scientists claim that within 10 years, this technique may be used to create new hearts for implanting into people.

Here's the link: https://www.livescience.com/65257-3d-printed-heart-human-tissue.html

Does anybody here with more medical expertise believe that one ought to include this in the article? --Thank You.

 * Also, here is a fairly recent article on an American team's generating pig's lungs.

1976 Tissue Regeneration Mentioned Three Times
The particular case of a non-diabetic patient regenerating a 3cm scar in 1976 thanks to insulin injections is mentioned three times in the article: Perhaps those separate instances could be combined into one?
 * 1) History of human tissue regeneration: History of regeneration techniques: Regeneration by instrument
 * 2) History of human tissue regeneration: History of regeneration techniques:Regeneration with drugs
 * 3) Induced regeneration in humans: Fat

 * Logically, citations can be used many times to cite and validate different premise in any article. IMO, there is nothing logically, or structurally wrong with one citation (something 1976) validating three separate, premise arguments, or structured subjects like that in any article. However, you would clearly have a great point if the same logical premise was mentioned three times in an article, but this is not the case as 'Regeneration by instrument', 'regeneration by drugs' and 'fat' are three different premise arguments.Melvapent (talk) 07:44, 13 November 2020 (UTC)

Regeneration by Recellularization
several of the examples in the 3D printing subsection actually use decellularization and subsequent recellularization of existing tissue. since this only involves washing the tissue and then dripping a cell culture solution on the remaining "ghost" tissue, it's not 3D printing at all. the micro- and macro-structure already exist in the ghost tissue and are not created by any sort of printer. recellularization should get its own subsection. 157.131.95.172 (talk) 01:40, 29 June 2021 (UTC)
