The extracellular matrix (ECM) of bone is considered to be a composite material made up of organic and inorganic matter. What makes up the organic and inorganic portions of the matrix? Describe the cellular mechanism involved in breaking down this matrix; include the bone cell required for the process.
In contrast, the cornea's Photoelectric-Responsive Extracellular Matrix for Bone Engineering Jieni Fu Hubei Key Laboratory of Polymer Materials, Ministry-of-Education Key Laboratory for the Green Preparation and Application of Functional Materials, School of Materials Science & Engineering, Hubei University, Wuhan 430062, People’s Republic of China Bones are constantly remodeled throughout life to maintain robust structure and function. Dysfunctional remodeling can result in pathological conditions such as osteoporosis (bone loss) or osteosclerosis (bone gain). 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). Abstract: The extracellular matrix (ECM) is a complex of self assembled macromolecules. It is composed predominantly of collagens, non-collagenous glycoproteins, hyaluronan and proteoglycans. ECM is not only a scaffold for the cells; it serves also as a reservoir for growth factors and cytokines and modulates the cell activation status and turnover. While extracellular matrix (ECM) is comprised of a complex mixture of diverse proteins that define structural integrity and function, collagen is the major component (~90%) of ECM proteins in bone.

A. F.; and Davies, J. E. (1993) "Organic Extracellular Matrix Components at the Bone Cell/Substratum Interface," Cells and Sep 1, 2018 Efficient osteogenic differentiation of mesenchymal stromal cells (MSCs) is crucial to accelerate bone formation. In this context, the use of Bone is composed of an extracellular matrix and bone cells (osteocytes). Under the right conditions, bone tissue undergoes a process of mineralization, formed Also at ventral ends of ribs and as ARTICULAR CARTILAGE on the bone surfaces within joints. Dominant component of extracellular matrix is collagen fibers.

Decellularized extracellular matrix (dECM) has been established as a biomaterial that preserves a tissue's native environment, promotes cell proliferation, and provides cues for cell differentiation. The potential of dECM as a therapeutic agent is rising, but there are many limitations of dECM restricting its use.
While extracellular matrix (ECM) is comprised of a complex mixture of diverse proteins that define structural integrity and function, collagen is the major component (~90%) of ECM proteins in bone. All members of the collagen family contain domains with proline-rich tripeptides (Gly-X-Y) that form trimeric collagen triple helices ( Gelse et al., 2003 ).

The ingredients necessary to make bone are: Cells + Organic Extracellular matrix (fibers +ground substance). This is then mineralized by calcium phosphate
It is composed predominantly of collagens, non-collagenous glycoproteins, hyaluronan and proteoglycans. ECM is not only a scaffold for the cells; it serves also as a reservoir for growth factors and cytokines and modulates the cell activation status and turnover. Acellular bone is ~30% collagen protein, like cement, and ~70% calcium salts, which act like bricks. Bone is made of a number of things, largely proteins and calcium-containing minerals, so that they are rigid and do not break easily, providing firm support for the body. Collagen is the most common protein in the human body and is found frequently in extracellular bone tissue, making up about Here we see the microscopic structure of bones that contains an extracellular matrix that surrounds cells. The extracellular matrix consists of about 15% water, 30% collagen fibers, and 55% crystallized mineral salts like calcium phosphate these then combines with another mineral salt, calcium hydroxide, to form crystals. 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 Bone matrix allows mineral salts such as calcium to be stored and provides protection for internal organs and support for locomotion.
