I noticed several posters talking about what stem cells can become. Stem cells are cells that can become many tissues and organs. The idea has been that these cells could be used to repair damaged organs or correct inherited disease. Parkinson's disease is caused because the cells that die make a substance called dopamine without which movement is often jerky or even impossible. Some people who have this disease cannot move at all.
Conventional treatment involves taking dopamine pills.
However, in other countries, investigators have injected embryonic stem cells into the brain that have been able to regrow and replace the cells that make dopamine allowing patients with this disease to have less problems with moving. The controversy is that these stem cells come from human embryos that have been therapeutically aborted. The question has always been how to eliminate the controversy and still be able to repair the diseased cells or organs. Funds for this type of research have been stopped by the United States government. At this meeting of blood doctors and scientists in San Francisco, nature's secrets were being revealed.
