In an effort to overcome these limitations, a team at the Wyss Institute for Biologically Inspired Engineering led by its Founding Director, Donald Ingber, M.D., Ph.D., had previously engineered a microfluidic «Organ - on - a-Chip» (Organ Chip) culture device in which cells from a human intestinal cell line originally isolated from a tumor were cultured in one of two parallel running channels, separated by a porous matrix - coated membrane from human blood vessel - derived endothelial cells in the adjacent channel.

To study this barrier and determine why a lack of blood flow causes it to leak, the researchers built a blood - vessel - on - a-chip model consisting of a channel lined with a layer of human endothelial cells surrounded by extracellular matrix within a microfluidic device, which allowed them to easily simulate and control the flow of blood through a vessel and evaluate the cells» responses.
