Part of the problem with using stem cell treatment for Autism is that we do not know what we are treating. Despite the eager promotion of varied „theories“ about what causes autism, there isn't any generally agreed on pathology or „lesion“ to treat. Even genetic studies fail to show one single genetic reason for autism, suggesting that what we call „autism“ is numerous different defects with an identical (or not so similar) appearance. Injecting stem cells in the imprecise hope that they're going to find the problem and fix it is dumb. Stem cells have no more notion of the correct way to „fix“ autism than we do – which is to assert, „none“.
The „good reports“ I referred to above is that, based primarily on the outlines of what they are doing, the clinics where parents are taking their autistic kids for „stem cell treatment“ are using – at best – multipotent blood stem cells. The outlines are far more promotional than educational, so it is entirely possible that their „techniques“ are yielding no stem cells whatsoever. This is „good“ because infusing real pluripotent stem cells into the blood or (worse yet) into the spinal liquid carries the danger of creating tumors without any known (or even suspected) potential for benefit.
A major consideration is that claimed „stem cell“ cures might or might not involve tangible stem cells. This is a particularly controversial technology (at the very least on this side of the pond), and so far as I'm able to tell even the advocates don't think it is anywhere near ready to be used as a treatment.
It happens to me that quacks getting hold of actual stem cells might be an inadvertent consequence of Bush’s denial of Fed. funding in the area. When legitimized research is underfunded, it's a foreseeable outcome that shady ventures will snatch up surplus resources.
stem cells are being employed in one or two illnesses previously regarded as „degenerative“ without cytotoxic treatment e.g. Cardiac arrest and Parkinson’s disease which are beginning to be recognised as inflammatory sicknesses.
We aren't looking for astonishing and straightforward discoveries where we just inject cells and poof, wizardry occurs, just more understanding. We don't see that getting said in public fairly often.
More generally we also wish to understand how organs (like adrenal glands) get made, which again impacts our thinking about the genes involved, and yes, there are some folks out there who ‘just ‘ need to be able to make new parts like heart valves from your own stem cells.
The critical genes/proteins/processes in stem cells are heavy hitters, and we will hardly imagine more understanding of them failing to be vital. Maybe that is hard to sell without going deep into precise examples though.
