Emphysema damages the alveoli—the air sacs in the lungs. Their walls stretch and break down, making the lungs larger and harder to breathe. It is the most common form of COPD, typically caused by long‑term smoking, and affects an estimated 200 million people worldwide. There is no cure. Endothelial Researchers at Weill Cornell Medicine and … Continue reading Endothelial cell treatment reverses lung damage in mice with emphysema

Support cells have different roles in blood stem cell maintenance before and after stress
A new study published in the journal Cell Stem Cell, reveals how different types of cells in the bone marrow are responsible for supporting blood stem cell maintenance before and after injury. It was already well known in the field that two different cell types, namely endothelial cells (which line blood vessels) and stromal cells … Continue reading Support cells have different roles in blood stem cell maintenance before and after stress
Confusing cancer to kill it
Confusion is not a state of mind that we usually seek out. Being bewildered is bad enough when it happens naturally, so why would anyone actively pursue it? But now some researchers are doing just that, using confusion to not just block a deadly blood cancer, but to kill it. Today the CIRM Board approved … Continue reading Confusing cancer to kill it
Stem cell-derived blood-brain barrier and Huntington’s disease
Our bodies use a protective barrier to shield the brain from harmful substances in the blood while still allowing essentials like glucose and oxygen to enter. As in other tissues, brain blood vessels are lined with endothelial cells. In the brain, these cells form extremely tight junctions, making it nearly impossible for most substances to … Continue reading Stem cell-derived blood-brain barrier and Huntington’s disease
Regenerating damaged heart muscle attack
Images of clusters of heart muscle cells (in red and green) derived from human embryonic stem cells 40 days after transplantation. Courtesy UCLA CIRM-funded researchers at UCLA have identified a way that could help regenerate damaged heart muscle, potentially not only saving lives of who've had heart attacks. Heart attacks Every year more than 735,000 … Continue reading Regenerating damaged heart muscle attack
