Extracellular matrix ecm - Study guides, Class notes & Summaries

Extracellular Matrix (ECM) - -relatively stable structural material that lies under epithelia & that surrounds connective tissue cells -can be divided into 2 structural components: fibers & amorphous ground substance Fibers - -an aggregate of fibrils -1-10 um diameter (largest) -can be divided into collagen & elastic -each is comprised of specific types of proteins -can assemble into bundles Fibrils - -an aggregate of filaments (filaments put together = fibrils) -20-500nm diameter -col...
