Scientists reach 'holy grail' of tissue engineering

Great news, maybe they can grow tissue for amputee's with diabetes or new eyes for the blind, the possibilities are endless!

Unlike other cell types in the body, most of our brain cells have very specific connections to other brain cells that form our thoughts and memories. If a brain cell dies from Alzheimer's, replacing that cell won't replace the connections it had with other cells.

If we were suddenly able to replace the brain cells in somebody with a lot of damage from Alzheimer's, that person still won't regain all the memories that were lost, or even the personality. The sad truth is that the person would still be a stranger to you, and vice-versa. Full "recovery" might even mean going back to school for years to relearn lost skills. Even if the Alzheimer's were caught early and we could do a continual replacement of brain cells, it's not clear that the person still wouldn't lose important memories over time.

Ultimately, the only solution for Alzheimer's is to find the cause of the disease and prevent it.

No, but people with brain injuries do relearn a lot of things, and if the Alzheimer's patient could get new cells, they may be able to have a better quality of life. Just getting back the short term memory would be a tremendous thing. If they could relearn simple math, or reading. Just being able to retain the name of the person caring for you.

As the stem cells are the base of the rest then it'll be great to apply such kind of invention in real. Is it suitable for the damaged cell? I'm waiting for more updates about this exclusive reveal. Thanks!
