What does stem cell research cure?
Knowing this – you SHOULD be able to get stem cells and introduce them into another organ and they SHOULD become that organs new cells. So if I have stem cells and a bad heart – I can introduce them into the heart and they will become new heart cells. With enough of them – I SHOULD be able to generate a new working heart – to replace the cells of an old poorly functioning heart! It is all theory – but it is very plausible!!
