Christianity Today reports:
[Scientists] have learned how to reprogram adult cells so that they can do many things an embryonic cell can do. No human embryos are destroyed in the process. Along the way, embryonic stem cells—just a decade ago hailed as the future of medicine—have largely been bypassed. Some researchers still use them, but for now, the future belongs to adult stem cells and iPS cells, which are adult cells genetically reprogrammed to express specific genes.
Every year for the past 10 years, the National Institutes of Health (NIH) has funded more adult stem cell research compared with embryonic research. For 2012, NIH grants totaled $146.5 million for embryonic stem cell research, but $504 million for adult stem cell research—a difference of $357.5 million. And the belief that adult stem cells are more promising than embryonic stem cells for therapies is now largely mainstream.
