Retina is a good example of this. Zebrafish can regrow damaged retina, but while mammals have the same stem cells (Muller glia), they dont repair the retina, but form scar tissue. There is a lot of research and I think they have managed to modify rat genome, so that their retina has showns some repair abilities. The problem is that it often causes tumors.
I have other retina permanently damaged, and suffer from double vision when looking small objects like text.
I was working on a project for 2 years with about 5 engineers. It was many years before AI. It was new subject for our team, and we were pretty sure it was possible. Turned out it was not.
Much later I asked AI if that kind of project is possible, and it immediately explained why it is not. Would have saved 2 years of our time...

After this it spawned always in middle, I also added property Position Remember, so it spawns where it was previously. I have no idea if this is the best way to fix but worked for me.
"Tar, acclaimed to have been formed from the sweat of Väinämöinen, a central character from the Finnish national epic Kalevala, was an important medicament to the former-day Finns. Tar actually did bear antiseptic features, which worked as a cure for infections. Lately tar has been recognised to include parts that can cause cancer, and the European Union has urged that its use should be avoided." [1]
I personally dont know how tar was used for health, but it was big export item of Finland during medieval times.
I have permanent damage on my retina of other eye. I hope one day humans could regenerate their retinas as sharks and zebrafish can do. Seems strange, that fish living in deep dark oceans can fix their eyes, while most mammals who rely on vision a lot more cannot.
