BTW, there are over 3000 clinical studies using stem cells in the Clinical Trials database.

Stem cells are precursors to cells that are in the body. Think of liver cells, blood cells, brain cells. They are useful if Trent has a disease or condition where his cells need to be replaced.
If you're thinking that you'd like to donate them instead of hanging on to them, just let them know at the place that stores them. Researchers search for sources, and would be happy to receive them.

Thanks @MartinCunningham. I looked and there are none for autism. Its discouraging. We banked Trents and have no way to use them.

What is ABA? I pay for storage on Trents stem cells every year. I wish I could find a way to use them...

Trentsmom,
Unfortunately there is no treatment for autism. The cause has not yet been pinpointed. Concerning the brain itself, one of the many hypotheses is that there are too many neurons present (1.9 billion compared to 1.1 billion in normal brains), and that all these other neurons are screwing up the normal connections.
If there's a possibility to use stem cells to treat autism, then it's at least 10 years away in my opinion.
