Could that possibly be because there haven't been any human trials yet, because of all the obstacles in the way?
For stuff sitting in glassware, though, there have been successes...such as "Researchers produce blood in the lab from [embryonic] stem cells" (Aug 2008):
Scientists said today that they have devised a way to grow large quantities of blood in the lab using human embryonic stem cells, potentially making blood drives a relic of the past.Are you one of the ghouls who is disappointed when research that can help save lives is successful?
But experts cautioned that although it represented a significant technical advance, the new approach required several key improvements before it could be considered a realistic alternative to donor blood.
The research team outlined a four-step process for turning embryonic stem cells into red blood cells capable of carrying as much oxygen as normal blood. The procedure was published online in the journal Blood.

Researchers have tried to harness the so-called adult stem cells that are responsible for making blood in the body, but their methods were far too inefficient to be put to practical use, experts said.
In the new study, researchers were able to make up to 100 billion red blood cells enough to fill two or three collection tubes from a single plate of embryonic stem cells.
I do not support taking a bad situation and making it worse.
'scuse me, but
You're the one who wants to take a situation where we have a long-gone embryo...and make it worse by not even using the byproduct of that long-gone embryo to help people. It's taking a bad situation and making it worse, by watching other people die who might potentially be saved by this research...and not a single embryo is being killed by this research going forward.
It blows my mind that you're against this trial proceeding.
I do not support the killing of unborn children on the rhetoric that some day it will do wonders, when there is no proof it has done any good.
Oh, you must have the wrong thread, since that's totally irrelevant to the research in this story.
Stop killing the unborn.
To whom is that addressed?!?
I see no reason to continue this discussion with you. You are on record here to be for killing embryos.
