the problem is that the basic science work for escr has been hampered. the report cites the following references:

scientists [color=#48537a]announced yesterday
that they had found stem cells in the amniotic fluid of pregnant women that have similar characteristics to embryonic stem cells. while these new stem cells hold great promise, they will not replace embryonic stem cells:
- there are questions over whether the amniotic-fluid stem cells can differentiate into as many types of cells as embryonic stem cells, thereby limiting their medical application.
- it is unlikely that amniotic-fluid stem cells will be as useful as embryonic stem cells for studying early human development, one of the most promising areas of stem cell research.
- scientists already know that stem cell research is not “one-size-fits-all”; different types of stem cells will be necessary to treat different types of injuries and diseases, so while these new stem cells will be medically useful, they will likely not replace embryonic stem cell research and therapies.
- it will take years for other scientists to reproduce these results, then try to convert them to materials that could be used first in animal models of human disease, and then test them in a few people for safety. meanwhile, we already know how to obtain embryonic stem cells, while the research continues to advance rapidly,
