Incredible to see some promising results in stem cell research. Hopefully a safe and successful application can give a boost to some other areas where stem cells might prove useful (like maybe one day we can regrow damaged heart tissue like this).
The notion of "stem cells" are somewhat of a misnomer as modern biotechnology is showing us. There are an orchestration of probably 1000s of different cell types which can vary in their cell states. We don't have enough knowledge of how to use these various cell types to influence complex self-organization processes like development. But in some cases there are clever fixes without understanding the underlying process.
Best news is the stem cells used are from donated placentas. So no political footballs, just a true blessing to a child.
