I have been in direct contact w/ 7 people now who had stem cells in Panama at SCI.
All of them except 1 have had good results, but all have had to return for more than 1 treatment.
One person had umbilical cord cells injected into his spinal canal, and his walking got worse.
There is also news reports on the cop from Texas who had the therapy with good results in 2008, he has had one further treatment, but he can now ride his bike in 50 mile races.
