skeletal system development

The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).

ossification

The formation of bone or of a bony substance, or the conversion of fibrous tissue or of cartilage into bone or a bony substance.

GO:0007275

multicellular organism development

The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).

extracellular matrix organization

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.

GO:0031214

biomineral tissue development

Formation of hard tissues that consist mainly of inorganic compounds, and also contain a small amounts of organic matrices that are believed to play important roles in their formation.

GO:0005576

extracellular region

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

CC

GO:0005578

proteinaceous extracellular matrix

A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus.

cytoplasm

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

extracellular matrix structural constituent

The action of a molecule that contributes to the structural integrity of the extracellular matrix.

GO:0005509

calcium ion binding

Interacting selectively and non-covalently with calcium ions (Ca2+).

TAS

MF

GO:0005518

collagen binding

Interacting selectively and non-covalently with collagen, a group of fibrous proteins of very high tensile strength that form the main component of connective tissue in animals. Collagen is highly enriched in glycine (some regions are 33% glycine) and proline, occurring predominantly as 3-hydroxyproline (about 20%).
