How do cells connect to extracellular matrix
WebCollagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. Collectively, these materials are called the extracellular matrix (). Not only does the extracellular matrix hold the cells together to form a tissue, but it also allows the cells within the tissue to communicate with each other. WebOct 16, 2024 · Loose irregular connective tissue contains numerous cells and a loose fiber arrangement in a moderately viscous fluid matrix. The dense irregular connective tissue has a dense woven network of collagen and elastic fibers in a viscous matrix. Dense connective tissue is found in joint capsules, muscle fascia, and the dermis layer of skin.
