Lazarius, my own experience in medicine is that my colleagues and peers are
vastly more in favor of stem cell research than the general population. This is a bit of a bias, though, because I've spent time at institutions that are international leaders in stem cell technology. That said, you find a lot more journal publications about progress with stem cells than you find opinion pieces expressing opposition.
Try this one on for size -- a few years ago I consulted on a patient with a very rare autosomal recessive primary immunodeficiency disease caused by deficiency of the NEMO gene in the NF-kappa-beta signal transduction pathway. Unable to find a bone marrow donor, his parents decided to have another child in the hopes that it would be a perfect HLA match
and be no worse than a heterozygote for the NEMO deficiency mutation.
But there's only a 25% chance that it would be a perfect HLA match and a 75% chance that it would be a heterozygous or homozygous dominant, meaning that there would only be an 18.75% chance that their new baby would be a suitable bone marrow donor.
So they did in vitro fertilization and selected embryos that were #1 perfect HLA matches, #2 did not have homozygous NEMO deficiency, and #3 were female so they could easily identify the engrafted cells. Hence, he got a sister who was a perfect bone marrow donor, and he's done great since then. The sister is adorable as well.
That's not exactly stem cell research, but it's as close as you'll get in clinical practice these days.
