If you have friends or family who struggle with vision issues, there is reason to be hopeful. Medical researchers may be close to a huge breakthrough, using stem cell technology to stabilize and perhaps improve vision in patients who are legally blind or vision-impaired. I know folks who are affected, so I've been following this story for awhile, and am hoping that we get definitive news from trial injections that were done in California this summer. The field of regenerative medicine strikes me as a fundamentally sound approach, rather than bombarding ourselves with toxic pharma products that mainly treat the symptoms. With health care costs getting out of control, perhaps stem cells offer a way for us to deal with health issues and the huge financial challenges associated with treatment of various ailments. The Chinese are very interested in stem cell therapy, and are already taking big steps in that direction.
