Scientists just made living blood vessels on a chip that act like real ones

Texas A&M University researchers have developed an advanced "vessel-chip" system that recreates the complex shapes of real human blood vessels, including branches, aneurysms, and narrowed areas, rather than simple straight tubes used in previous lab models. These microfluidic devices contain living endothelial cells and allow scientists to study how different vessel shapes affect blood flow patterns and disease development. The customizable chips provide a powerful platform for testing treatments without animal testing and understanding vascular diseases in realistic conditions.
