I'm so lost in this discussion
Cheerful do you need to write a paper or something in Ethics?
Human genes are being cloned everyday AND on a computer chip... Now, that technology, wow. If I had money back in 1994 when Affymetrix started!!!
We can grow organoids in petri plates. We do it with stem cells all the time. Well, depending on how your look at it, the US cannot use Human Embryonic Stems so we scientists are WAAAY behind on that research curve. While Singapore and North Korean gives us bogus data on that subject...
The issue with providing correctional "parts" to damaged tissues is the honing to the area. It's easiest with skin. It's harder with nerves. And add a chronic illness into the mix, like cancer or heart failure, good luck...
And NONE of these studies are being done in the US anymore! So, don't get cancer unless your Senator Kennedy, or lose a limb, or have heart failure because, welp, you are NOT going to be saved with our current healthcare system.
I'd say the US is now 5 years behind other 1st world countries research...
