LOS ANGELES, March 16, 2007 - Just a month after approving nearly $45 million for embryonic stem cell research, California's stem cell agency authorized another $75.7 million in additional funds for established scientists at 12 non-profit and academic institutions. (ca.gov)
The California spirit - the perseverance, creativity and resourcefulness that has made us a leader on everything from gold mining in the 19th Century to fighting global warming in this one - is fully present in our stem cell research teams. (ca.gov)
As of today, California is the largest and most stable source of funding for human embryonic stem cell research in the world," Klein said. (ca.gov)
These grants provide substantial support to a pool of very distinguished researchers in human embryonic stem cell research," declared Zach W. Hall, Ph.D., CIRM's President and Chief Scientific Officer. (ca.gov)
Combined with our training and SEED grants, the CIRM is now funding embryonic stem cell research in more than 100 California laboratories. (ca.gov)
We focused our initial grants on human embryonic stem cells specifically," Klein said, "because human embryonic stem cell research receives minimal funding from the federal government, and even those funds are restricted to lines of questionable value. (ca.gov)
Going forward, we will support a diverse range of stem cell research projects. (ca.gov)
And he also agrees that if we don't find global agreement on human cloning, "we can probably expect dire consequences for the future of biomedical research and its impact on society at large. (lifeissues.net)
As he has questioned the HFEA before, would not the use of vulnerable human patients in clinical trials be premature, dangerous, and unethical given the already acquired knowledge in the research community that such supposed "patient-specific" stem cells would most probably cause serious immune rejection reactions in these patients?

Research involving human neural organoids, transplants, and chimeras has an ultimate goal of preventing and treating the great suffering caused by serious neurological and psychiatric conditions for which no effective treatment is available. (nationalacademies.org)
One such concern is the possibility of altering the capacities or consciousness of a research animal in ways that may blur the lines between human beings and nonhuman animals. (nationalacademies.org)
A main justification for carrying out research, both basic and translational, with human neural organoids, transplants, and chimeras is that it will help in the discovery of new ways to understand and treat neurological and psychiatric disorders, which, as discussed previously, cause immense suffering and for which treatments are ineffective or lacking.
