The first mammals, around 200 million years ago, were small, four-legged and relatively unspecialised. |
The basic skills are relatively simple and unspecialised, allowing for mass participation. |
Early embryos are potentially a better source because all their cells are still unspecialised. |
Stem cells are unspecialised cells that are able to replicate and can be influenced by their environment to take on specialised properties. |
After more than 6 months of unspecialised growth the cells retained the potential to form particular tissues. |
What worries me is that prospective patients are increasingly at risk due to poor regulation and sometimes unspecialised, greedy doctors and practitioners. |
