Fig. 2From: Engineering and monitoring cellular barrier modelsPhysical and biochemical cues in the cell microenvironment. Schematic drawing of an epithelial tubule and an endothelial capillary embedded within an ECM. It includes cell-cell communications (i.e., direct contact, autocrine, and paracrine communications), flow-induced shear stress, ECM involving basement membrane and interstitial matrix components, and cell-ECM interaction through membrane receptor proteinsBack to article page
