In connective tissue (CT), the ECM component predominates relative to the ...o Cell and matrix connections: Specialized cell contacts bind adjacent epithelial cells together an to the extracellular matrix of the basement membrane. o Nonvascular: Blood vessels in the underlying connective tissue do not penetrate the basement membrane to reach the epithelium: thus, all gases and nutrients carried in the blood must reach ...Nov 23, 2021 · The connective tissue in general is comprised of 3 groups of proteins: collagens, proteoglycans and a variety of different glycoproteins. In addition to the main weight-bearing structural proteins of connective tissue – the fibril forming collagens (discussed in Chap. 2) – as well as the often hydrophilic role of proteoglycan proteins (discussed in Chap. 6), growth factors (see Chap. 7 ... Collagen (/ ˈ k ɒ l ə dʒ ə n /) is the main structural protein in the extracellular matrix found in the body's various connective tissues. As the main component of connective tissue, it is the most abundant protein in mammals, making up from 25% to 35% of the whole-body protein content.Definition.

The connective tissue of an organ is usually referred to as the stroma. This tissue type can have very different structures according to the proportions …Connective tissue disorders may be due to mutation of genes or by inherited faulty genes. The two genetic disorders of connective tissue are epidermolysis bullosa (EB) and Marfan syndrome. Marfan syndrome is due to defective genes producing a protein fibrillin-1.
