New material for creating artificial blood vessels

Blocked blood vessels can quickly become dangerous. It is often necessary to replace a blood vessel – either by another vessel taken from the body or even by artificial vascular prostheses. Together, Vienna University of Technology and Vienna Medical University have developed artificial blood vessels made from a special elastomer material, which has excellent mechanical properties. Over time,…

Stellate cells control regeneration and fibrosis

Scientists from the German Cancer Research Center (DKFZ) and the Medical Faculty in Mannheim at Heidelberg University are searching for new approaches to prevent liver fibrosis. They have identified a surface molecule on special liver cells called stellate cells as a potential target for interfering with this process. When the researchers turned off the receptor, this led to reduced liver…
