Depending on the size & distribution of the spaces, the regions of a bone may be categorized as compact or spongy, about 80% of the skeleton is compact bone and 20% is spongy bone. Extracellular Matrix. The use of decellularized extracellular matrices (ECM), often derived from xenogeneic sources, has been shown to favorably influence the immune response to injury and promote site-appropriate tissue regeneration. ECM components, as well as cell adhesion receptors, interact with each other forming a complex network into which cells reside in all tissues and organs. All epithelial cells as well as some other types (e.g., smooth muscle cells) are attached to a basal lamina (also known as the basement membrane) [View]. Bone. It serves as a packing and binding material for most of our organs. Matrices: A, Simple metal strip with a wooden wedge. eCollection 2020. Sheets of loose connective tissue that bind muscles and other structures together are called fascia. The matrix of bone contains collagen fibers and mineral deposits. Bone contains 100s of extracellular matrix (ECM) proteins and the ECM of the various bone tissue compartments plays essential roles directing the remodeling of bone through the coupled activity of osteoclasts (which resorb bone) and osteoblasts (which produce new bone). Bone, or osseous tissue, is a connective tissue that constitutes the endoskeleton.It contains specialized cells and a matrix of mineral salts and collagen fibers.
