Stem Cell donation leads to tumor.

Very interesting. Apparently this boy suffers from a nuero disorder so his parents seeks these Russian Scientists who extracted nuero stem cells from aborted fetuses and implanted them in the child. 4 years later the kid developed a brain tumor. Tests performed on the brain tumor discovered the tumor originated from the brain tumor.

Now scientists are wondering if the nuero stem cells donation increase the risk of donar developing a brain tumor or if the brain tumor occurred because of the child weak immune system.

Another possibility is the stem cells that were implanted in the child were not really stem cells which would probably help better explain why this all happened. Whatever the case I think this needs further study. I feel sorry for this child.
