stanford stroke stem cell study

Then, using the iPSC method, they turned those cells into brain neurons and compared them to the neurons of individuals with no family history of schizophrenia. Sonia Olea Coontz had a stroke in 2011 that affected the movement of her right arm and leg.

She enrolled in the Stanford trial after finding out about it during an online search. Steinberg said it’s likely that factors secreted by the mesenchymal cells during their early postoperative presence near the stroke site stimulates lasting regeneration or reactivation of nearby nervous tissue. Steinberg began testing this in a small trial that ran between 2011 and 2013. It was focused on the use of stem cells and recovery from a stroke and featured three great guests: Dr. Gary Steinberg, chief of Neurosurgery at Stanford, Sonia Coontz, a patient of Dr. Steinberg’s, and CIRM’s own Science Officer Dr. Lila Collins. Stanford Medicine integrates research, medical education and health care at its three institutions - Stanford University School of Medicine, Stanford Health Care (formerly Stanford Hospital & Clinics), and Lucile Packard Children's Hospital Stanford. With permission from Dr. Stephen Smith. The promising results set the stage for an expanded trial of the procedure now getting underway. Stroke occurs in 15 million individuals each year worldwide, and is the second leading cause of mortality. Theoretically, the results of the stem cell research experiment could lead to better treatments for brain damage resulting from strokes, spinal cord injuries, traumatic brain injury, and even, potentially, Alzheimer’s disease. Right: Human neural progenitor cells (red) are found in close proximity to blood vessels (green). Some studies compare healthy people to those who have a specific disease. Figure 2. Our approach integrates the advanced proteomic imaging technique, array tomography, to accurately identify and count excitatory and inhibitory synapses (Figures 2 & 3), and electrophysiology techniques to measure functional changes at the synaptic and circuit level. For the trial, the investigators screened 379 patients and selected 18, whose average age was 61. Their ability to move around has recovered visibly. “Some patients couldn’t walk,” Steinberg said. Consequently, only a small fraction of patients benefit from treatment during the stroke’s acute phase. Pre- and post-synaptic marker colocalization as seen with array tomography, an imaging method co-invented by Stephen Smith, PhD and Kristina Micheva, PhD at Stanford. Researchers at Stanford reported that they are “stunned” by the results of an experimental treatment to treat stroke patients. The patients, all of whom had suffered their first and only stroke between six months and three years before receiving the injections, remained conscious under light anesthesia throughout the procedure, which involved drilling a small hole through their skulls. Into these patients’ brains the neurosurgeons injected so-called SB623 cells —mesenchymal stem cells derived from the bone marrow of two donors and then modified to beneficially alter the cells’ ability to restore neurologic function. Now 36, Coontz had a stroke in May 2011. “If this treatment really works for that huge population, it has great potential.”.
