- 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’m surprised this does not mention humans can grow back the tips of their fingers (past the white part of cuticle) https://www.npr.org/sections/health-shots/2013/06/10/1903854...
Supposed to be only kids but I’ve chopped off a few mm by accident it came back as an adult or I can’t tell the difference.

- Not a single mention of the work on limb regeneration by Professor Michael Levin's lab at Tufts?

- In a study they figured out that organs seem to have an electrical potential range as a signature/command for stem cells for which organ to build and where.
In a frog they were able to grow legit eyes in the gut just by artificialy inducing a certain voltage in that area. No need for any cell transplantations: the voltage really seems to be the only signal needed.
This might also be how it might be done in the future in humans: block scar tissue then induce voltage with the signature of the organ you wish to regrow.

- The trick is to make regeneration fast enough to heal the wound without making fast enough to cause cancer. Maybe even supported by provisional fibrosis.
- It's just hidden by a feature flag.
(Probably for a good reason)

- Wasn't this proven many years ago by a random guy who used a "extra-cellular matrix" of stem cells to regrow his severed finger, nail and all?

- I'm hoping that this can be applied to routine genital mutilation in humans that are often done near birth and without consent.
- Perhaps humans can one day regrow their teeth for better food ingestion when elderly and cognitive function.

- Maybe that's what Jesus used on the people that he healed
