Japanese researchers' experiments show that brain-injured rats that are injected with stem cells are greatly enhanced in functional recovery. The stem cells were injected via the carotid artery, where it traveled directly to the brain. Before injection the stem cells were labeled with quantum dots. The dots emit near infrared light. This allowed the researchers to monitor the stem cells for 4 weeks after the injection without affecting the patient. So, they were able to see the stem cells enter the brain immediately, without entering the general circulation. After 4 weeks, the rats that had been injected with stem cells had a significant recovery of movement, while rats without had no recovery. Examination of the brains with stem cells confirmed that the stem cells had transformed into different brain cells and helped the healing process of the injured brain area. This process of injecting stem cells into the carotid artery is relatively simple and the bone marrow stem cells used are a promising source of donor cells. Therefore, I am for stem cell research and use.
