Researchers at UBC show that two types of cells, astrocytes and pericytes, cooperate to regenerate cerebral blood vessels to restore blood flow in brain regions damaged by stroke.
Stroke is one of three leading causes of death in Canada and leads to permanent disability in about half of survivors. During an ischemic stroke, there is a blockage of blood flow which results in cell death in a specific area or the brain. Dr. Brian MacVicar and Dr. Louis-Philippe Bernier at the University of British Columbia has recently discovered how two types of cells, called astrocytes and pericytes, work together to regenerate blood flow in the areas affected by these strokes (called ischemic areas). These results were presented at the 2018 Canadian Neuroscience Meeting, in Vancouver, May 16th, 2018.
