Bone mineral (also called inorganic bone phase, bone salt, or bone apatite) is the inorganic component of bone tissue. It gives bones their compressive strength . Bone mineral is formed predominantly from carbonated hydroxyapatite [ 1 ] [ 2 ] with lower crystallinity.
Carbon is another alternative with similar mechanical properties to bone, and it also features blood compatibility, no tissue reaction, and non-toxicity to cells. Bioinert ceramics do not exhibit bonding with the bone, known as osseointegration. However, bioactivity of bioinert ceramics can be achieved by forming composites with bioactive ceramics.
Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralised matrix of bone tissue has an organic component of mainly collagen called ossein and an inorganic component of bone mineral made up of various salts. Bone tissue is mineralized tissue of two types, cortical bone and ...
In bone for example, the organic layer is the protein collagen. [3] The degree of mineral in mineralized tissues varies and the organic component occupies a smaller volume as tissue hardness increases. [1] [18] However, without this organic portion, the biological material would be brittle and break easily.
Bone, which has a very similar chemical make-up to ivory, consists of inorganic materials which provide strength and rigidity and organic components that provide the capacity for growth and repair. Unlike ivory, which has no marrow or blood vessel system, bone has a spongy central portion of marrow from which extend tiny blood vessels; bone is ...
Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed. In animal tissue culture, cells may be grown as two-dimensional monolayers (conventional culture) or within fibrous ...
The basis of bone tissue engineering is that the materials will be resorbed and replaced over time by the body’s own newly regenerated biological tissue. [ 60 ] Tissue engineering is not only limited to the bone: a large amount of research is devoted to cartilage, [ 64 ] ligament, [ 65 ] skeletal muscle, [ 66 ] skin, [ 67 ] blood vessel, [ 68 ...
Bone decalcification is the softening of bones due to the removal of calcium ions, and can be performed as a histological technique to study bones and extract DNA. [ 1 ] [ 2 ] This process also occurs naturally during bone development and growth, and when uninhibited, can cause diseases such as osteomalacia .
