How do cells connect to extracellular matrix
WebThe extracellular matrix (or ECM) consists of a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding [ more specialized] cells. One very familiar example of "matrix" tissue is connective tissue. Here's a video from Khan Academy's Youtube channel to walk you through this a bit. WebThe three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes. These types of junctions have different purposes, and are found in different places. Gap Junctions Gap junctions are essentially tubes that join two cells …
