The insulin-like growth factors I and II are single chain polypeptides homologous to proinsulin. IGF I and IGF II contribute to cell regulation and stimulate protein synthesis via signaling through type 1 receptors which are homologous to insulin receptors and activate phosphorylation cascades. IGFs enhance the proliferation of chondocytes and the proliferation of their collagen and proteoglycan matrix; IGFs stimulate longitudinal (endochondral) bone growth. Throughout life, IGFs are constitutively expressed ubiquitous factors which help to maintain the survival of differentiated cells, Increased expression is found during growth and tissue repair, Six specific binding proteins, IGFBP 1-6, allow additional tissue compartment specific control of IGF activity; IGFBP production favours storage and IGFBP cleavage leads to activation.

UI MeSH Term Description Entries
D007335 Insulin-Like Growth Factor II A well-characterized neutral peptide believed to be secreted by the LIVER and to circulate in the BLOOD. It has growth-regulating, insulin-like and mitogenic activities. The growth factor has a major, but not absolute, dependence on SOMATOTROPIN. It is believed to be a major fetal growth factor in contrast to INSULIN-LIKE GROWTH FACTOR I, which is a major growth factor in adults.

D010006 Osteoblasts Bone-forming cells which secrete an EXTRACELLULAR MATRIX. HYDROXYAPATITE crystals are then deposited into the matrix to form bone. Osteoblast
D010024 Osteoporosis Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.

D011509 Proteoglycans Glycoproteins which have a very high polysaccharide content. Proteoglycan,Proteoglycan Type H
D001846 Bone Development The growth and development of bones from fetus to adult. It includes two principal mechanisms of bone growth: growth in length of long bones at the epiphyseal cartilages and growth in thickness by depositing new bone (OSTEOGENESIS) with the actions of OSTEOBLASTS and OSTEOCLASTS. Bone Growth

D002356 Cartilage A non-vascular form of connective tissue composed of CHONDROCYTES embedded in a matrix that includes CHONDROITIN SULFATE and various types of FIBRILLAR COLLAGEN. There are three major types: HYALINE CARTILAGE; FIBROCARTILAGE; and ELASTIC CARTILAGE. Cartilages
D002454 Cell Differentiation Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs. Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D002455 Cell Division The fission of a CELL. It includes CYTOKINESIS, when the CYTOPLASM of a cell is divided, and CELL NUCLEUS DIVISION. M Phase,Cell Division Phase,Cell Divisions,Division Phase, Cell,Division, Cell,Divisions, Cell,M Phases,Phase, Cell Division,Phase, M,Phases, M
