Wheelchair-Bound Stroke Victim Walks Again After 'Unprecedented' Stem Cell Trial At Stanford (washingtonpost.com)
An anonymous reader quotes a report from The Washington Post: 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. 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 work involved patients who had passed the critical six-month mark when recoveries generally plateau and there are rarely further improvements. Each participant in the study had suffered a stroke beneath the brain's outermost layer and had significant impairments in moving their arms and-or legs. The one-time therapy involved surgeons drilling a hole into the study participants' skulls and injecting stem cells in several locations around the area damaged by the stroke. These stem cells were harvested from the bone marrow of adult donors. They suffered minimal adverse effects such as temporary headaches, nausea and vomiting. "Their recovery was not just a minimal recovery like someone who couldn't move a thumb now being able to wiggle it. It was much more meaningful. One 71-year-old wheelchair-bound patient was walking again," said Steinberg, the study's lead author and chair of neurosurgery at Stanford who personally performed most of the surgeries. Steinberg said that the study does not support the idea that the injected stem cells become neurons, as has been previously thought. Instead, it suggests that they seem to trigger some kind of biochemical process that enhances the brain's ability to repair itself. "Patients improved by several standard measures, and their improvement was not only statistically significant, but clinically meaningful," Steinberg said. "Their ability to move around has recovered visibly. That's unprecedented. At six months out from a stroke, you don't expect to see any further recovery."
This could save not just suffering but money - round-the-clock care isn't cheap.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
And "OH" -- the most interesting part (I didn't read the article cited in TFA, but I've read a few on this subject and know one of the folks in the trial) is that the stem cells die off pretty quick. They just seem to "spark" brain cells to go "Hey guys! Lets hold hands" and magically make new connections.
I donate blood every eight weeks (over 10 gallons so far). I have been on the marrow donor list for several years, but have never been matched with anyone. If/when the call comes, I will donate, and have no expectation of compensation. The procedure is very low risk and usually harmless.
They did these trials with fetal stem cells years ago. You can google for teeth growing inside head and other untoward results with fetal stem cells. Adult stem cells are less apt to do the surprising and undesirable things. [And more likely to be available.]
