So, once again the damned-with-faint-praise adult stem cell field seems headed toward significant treatment breakthroughs. This time stroke.
Grain of salt. Grain of salt. Grain of salt. Sometimes studies such as this do not bear fruit later on.
Stanford researchers studying the effect of stem cells injected directly into the brains of stroke patients said Thursday that they were “stunned” by the extent to which the experimental treatment restored motor function in some of the patients.
While the research involved only 18 patients and was designed primarily to look at the safety of such a procedure and not its effectiveness, it is creating significant buzz in the neuroscience community because the results appear to contradict a core belief about brain damage — that it is permanent and irreversible.
The results, published in the journal Stroke, could have implications for our understanding of an array of disorders including traumatic brain injury, spinal cord injury and Alzheimer’s if confirmed in larger-scale testing. The stem cells involved came from bone marrow, not destroyed embryos.
Grain of salt. Grain of salt. Grain of salt. Sometimes early studies such as this come to naught.
Still, not bad for a field that just 15 years ago was denigrated as NOT NEARLY AS HOPEFUL AS EMBRYONIC [STEM CELLS] by “the scientists” seeking the almighty funding buck–not to mention branding adult stem cell advocates as “anti-science for expressing significant ethical concerns and scientific doubts about the embryonic approach.
How many embryonic studies, formerly touted widely as the “only hope,” have there been this hopeful with humans?
That would be a big fat zero.
