I have personal experience with artificial skin products. Someone close to me had a persistent wound on their lower leg that would not heal. Repeated debridement, hyperbaric oxygen, and such didn't get it to heal, but application of patches of a (then new) cultured skin product healed it immediately. Huge QoL improvement.

every country have a dozen start ups rushing to patent the same thing globally.

it's mostly a game or passing trials for something that's obviously good and the alternative so far have 100% death* (burns over 80%). it just shows how ineffective is the whole system.

* but the investors are way more interested in permanent wound cases and they will price those like they usually price things with low mortality but high quality is life.
