Geron, a California-based cell-therapy company that has been working with embryonic stem cells for the last decade, finally received clearance from the U.S. Food and Drug Administration to begin clinical trials of its cell-based therapy for spinal-cord injury.
The trial is limited to eight patients with newly acquired spinal-cord injuries who will receive injections of the cell therapy, called GRNOPC1, within two weeks of their accident. GRNOPC1 is made by transforming embryonic stem cells into oligodendrocytes--a type of brain cell that wraps itself around neurons, forming a fatty insulation layer that allows electrical messages to be conducted throughout the nervous system. In many spinal-cord injuries, these cells are damaged, but the underlying nerve cells remain intact. These cells are then injected into the site of the injury, coating exposed nerves and restoring communication to the nervous system.
Comment: Experimenting with potential humans to me is unethical. I wish they could use adult stem cells or the stem cells in our noses instead of embryos, but this is what our president is allowing.
