From Charles #19 link (wikipedia, be forwarned):

It is often claimed by pro-life supporters that the use of adult stem cells from sources such as umbilical cord blood has consistently produced more promising results than the use of embryonic stem cells.[30] Furthermore, adult stem cell research may be able to make greater advances if less money and resources were channeled into embryonic stem cell research.[31]

Adult stem cells have already produced therapies, while embryonic stem cells have not.[32][33] Moreover, there have been many advances in adult stem cell research, including a recent study where pluripotent adult stem cells were manufactured from differentiated fibroblast by the addition of specific transcription factors. [34] Newly created stem cells were developed into an embryo and were integrated into newborn mouse tissues, analogous to the properties of embryonic stem cells.

This argument remains hotly debated on both sides. Those critical of embryonic stem cell research point to a current lack of practical treatments, while supporters argue that advances will come with more time and that breakthroughs cannot be predicted.


[edit] Scientific flaws
The use of embryonic stem cells in therapies may be fundamentally flawed.

For instance, one study suggests that autologous embryonic stem cells generated for therapeutic cloning may still suffer from immune rejection.[35] The researchers note that: “Our results raise the provocative possibility that even genetically matched cells derived by therapeutic cloning may still face barriers to effective transplantation for some disorders.” In other words, therapeutic cloning may not always produce tissues immune to rejection. In contrast, there are reports of adult stem cells being successfully reintegrated into an autogenic animal.

Another concern with embryonic stem cell treatments is a tendency of stem cells from embryos to create tumors

I am not even remotely close to being even moderately literate on this subject, but as the aformentioned quotes indicate, there is some scientific debate on the value of human embyonic stem cells.
And I do wish people would stop cracking “jokes” about people shaking and all - these are TERRIBLE diseases that sceince is wrestling with and for which the victims cannot be blamed in any way.
