Aerobic-anaerobic interface in a colon chip to study host microbe interaction

Not many systems can mimic the Aerobic-Anaerobic interface of the large intestine. A not-so-old paper from the Wyss institute creates a hypoxic gradient across their intestine-on-a-chip. In this study, the chip comprised epithelial cells on top of a porous membrane and bacteria cultured above the epithelium under a hypoxia...
