The human cardiovascular system is an intricate, complex network of blood vessels that include arteries, capillaries and veins. These structures distribute blood from the heart to all parts of the body, from our head to our toes, and back again. This week, two groups of scientists published studies showing that they can create key components … Continue reading One day, scientists could grow the human cardiovascular system from stem cells

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
Scientists use cotton candy to make artificial blood vessels
Gelatin mold with cotton candy made channels. Cotton candy gets a bad rap. The bright, sugary cloud is known for sending kids into hyperdrive and damaging teeth. Usually found at fairs or stadiums, cotton candy is now showing up in labs as a tool to help scientists build artificial blood vessels for lab‑grown organs. From snack … Continue reading Scientists use cotton candy to make artificial blood vessels
