Some researchers have suggested that umbilical cord blood stem cells might be as pluripotent as researchers theorize embryonic stem cells to be, that is, that they can be transformed into any kind of cell. Both theories remain unproven since it hasn’t yet been done yet with any kind of stem cell. But here is some evidence of the versatility of UBC stem cells. They were morphed into lung tissue that already looks to be usable for drug testing and research, and someday, hopefully, for medical treatments. And remember, just a few weeks ago, UK scientists announced that UCB stem cells were used to create small sections of liver tissue, as well. That’s real progress.
I credit President Bush for at least some of the focus and success we are seeing from non embyonic sources. Remember, back in 2001, political-scientists were saying the real action was embryonic. That did not prove to be true, and perhaps some of these wonderful advances were made because Bush kept the ethics of these matters forefront, allowing resources and energy to be invested that might otherwise have been diverted by the stampede to do ESCR.
