Adult Stem Cells May Help Childhood Motor Neuron Disease

Unfortunately I'm not aware of human trials in the US related to the therapy above (although there are others http://clinicaltrials.gov/ct2/results?term=SMA+type+1). I have read about injections that can be obtained abroad which are fairly expensive and not guaranteed.

Perhaps it would be best to contact the study investigator cited by David Prentice:

Look at www.stemcells21.com - an advisory/guidance service that is free and focused on helping people find the best service providers in the rapidly growing adult stem cell industry. Note we avoid anything to do with embryonic stem cells.
We have a physician here in Bangkok very experienced and interested in conditions like your sons.
