Roger,
There are more than a few places to go for stem cell treatments in China, and else where (Portugal, Germany, Netherlands, India, Argentina, South Africa etc.) All the places that I've read about are attempting to treat SCI and none of them are based on the standardized clinical trail system that we use here and in Europe. In fact all surgeons and hospitals are charging their patients, which brings ethics into question, since no procedure has been proven yet and patients are usual in a desperate condition.
When I flew to London at the onset of my injury, it was in attempt to get Dr. Thomas Carlstedt (one of the few neurosurgeons in the world that has exerience with reimplantion of avulsed nerves) to fly to Portugal and reimplant my avulsed nerves using adult neural stem cells from my nose with Dr. Carlos Lima. Lima has been at this now for about four years and with very limited success with SCI patients only.
In China they have have been using fetal nasal cell (olfactory ensheathing glial cells), adult nasal cells, umbilical cord blood stem cells, embryonic stem cells, bone marrow stem cells, myelin sheath cells (outermost insulating layer of the peripheral nerve) for attempted treatment of SCI. Very very few of these surgeons conducting these experiental procedures have published any of their results in any medical journals, which puts the question to their reported successes. The only actual certified clinic trial taking place in China is to start very soon, involving umbilical cord blood stem cells and lithium as a growth factor. These trials have been initiated by an American SCI researcher, Dr. Wise Young of Rutgers University. He has worked tirelessly to establish a SCI clinical trial network in China, ChinaSCINet, because of the difficulties establishing one here in the States (which is a very sad reality).
Most of the research I read and gather is accumulated in one source by thousands of individuals in the SCI community. It's a website started again by Dr. Wise Young, Christopher Reeves top neurologist as well, based out of Rutgers.

I read this site almost daily, and any progress that is posted there, will make it here as long as I still have hope for a cure.
My interest in the possibilities stem cells started after viewing a special on PBS called "Miracle Cell" back in April of 2003. Professor Geoffrey Raisman, on of the world leading researchers in the Central Nervous System, neural development, and nasal stem cells is currently starting clinical trials in the UK for TBPI, is interviewed and discusses the abilities and miraculous potentials of these cells. You can download the 1 hour show, which I highly recommend, from a site I have it hosted on:

The reason why most people will get return of function that have SCI is because it only takes 10% of the spinal cord to remain intact to be able to be ambulatory again. And the supposed reason for a good portion of successes in China, and such, from these experimental surgeries is the intense ongoing physical therapy that is required and implemented after these procedures are preformed. I believe the promise is there, but you can't just blindly throw stem cells at an injury and expect results, they have to be differentiated into neural cells first and then the right kind of neural cells, the inhibitory growth factors that exist in the Central Nervous System must be suppressed and growth stimulators must be activated, and scar tissue that creates a barrier is an obvious concern as well.
The great thing is that there is ongoing research in all these areas and after 4 years of constant research I feel the time is very close where newly injured people will have a much better prognosis them is currently available and then eventually the chronically injured will benefit as well. I think the best thing we can do to accelerate this research is to donate money, promote fund raising and public awareness. Researchers are constantly strapped for cash and spend an unfortunate large amount of their finite time conducting fundraising themselves instead time in the laboratory where I'm sure they'd all rather be.
