  2. Insulin-like growth factor 1 - Wikipedia

    en.wikipedia.org/wiki/Insulin-like_growth_factor_1

    Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a hormone similar in molecular structure to insulin which plays an important role in childhood growth, and has anabolic effects in adults. [5]

  3. Insulin-like growth factor - Wikipedia

    en.wikipedia.org/wiki/Insulin-like_growth_factor

    Insulin-like growth factor 2 (IGF-2, at times IGF-II) is thought to be a primary growth factor required for early development while IGF-1 expression is required for achieving maximal growth. Gene knockout studies in mice have confirmed this, though other animals are likely to regulate the expression of these genes in distinct ways.

  4. Growth factor - Wikipedia

    en.wikipedia.org/wiki/Growth_factor

    A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. [1] Usually it is a secreted protein or a steroid hormone .

  5. Insulin-like growth factor 1 receptor - Wikipedia

    en.wikipedia.org/wiki/Insulin-like_growth_factor...

    The insulin-like growth factor 1 (IGF-1) receptor is a protein found on the surface of human cells. It is a transmembrane receptor that is activated by a hormone called insulin-like growth factor 1 and by a related hormone called IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF-1 ...

  6. Bone growth factor - Wikipedia

    en.wikipedia.org/wiki/Bone_growth_factor

    A bone growth factor is a growth factor that stimulates the growth of bone tissue. [1] [2]Known bone growth factors include insulin-like growth factor-1 (IGF-1), insulin-like growth factor-2 (IGF-2), transforming growth factor beta (TGF-β), fibroblast growth factors (FGFs), platelet-derived growth factor (PDGF), parathyroid hormone-related peptide (PTHrP), bone morphogenetic proteins (BMPs ...

  7. Growth hormone - Wikipedia

    en.wikipedia.org/wiki/Growth_hormone

    GH also stimulates, through the JAK-STAT signaling pathway, [39] the production of insulin-like growth factor 1 (IGF-1, formerly known as somatomedin C), a hormone homologous to proinsulin. [40] The liver is a major target organ of GH for this process and is the principal site of IGF-1 production. IGF-1 has growth-stimulating effects on a wide ...

  8. Fibroblast growth factor 1 - Wikipedia

    en.wikipedia.org/wiki/Fibroblast_growth_factor_1

    Fibroblast growth factor protein was first purified in 1975, but soon afterwards others using different conditions isolated acidic FGF, Heparin-binding growth factor-1, and Endothelial cell growth factor-1. [7] Gene sequencing revealed that this group was actually the same growth factor and that FGF1 was a member of a family of FGF proteins.

  9. TGF beta 1 - Wikipedia

    en.wikipedia.org/wiki/TGF_beta_1

    Transforming growth factor beta 1 or TGF-β1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth , cell proliferation , cell differentiation , and apoptosis .
