Product Description:
IGF-1 plays a crucial role in muscle regeneration. IGF-1 stimulates
both proliferation and differentiation of stem cells in an
autocrine-paracrine manner, although it induces differentiation to a
much greater degree. IGF-1,when injected locally, increases satellite
cell activity, muscle DNA, muscle protein content, muscle weight and
muscle cross sectional area. The importance of IGF-1 lies in the fact
that all of its apparent functions act to induce muscle growth with or
without overload although it really shines as a growth promoter when
combined with physical loading of the muscle.
IGF-1 also acts as an
endocrine growth factor having an anabolic effect on distant tissues
once released into the bloodstream by the liver. IGF-1 possesses the
insulin-like property of inhibiting degradation, but in addition can
stimulate protein synthesis. The insulin-like effects are probably due
to the similarity of the signaling pathways between insulin and IGF-1
following ligand binding at the receptors.
The ability of IGF-I to
stimulate protein synthesis resembles the action of GH, which was shown
in separate studies on volunteers to stimulate protein synthesis without
affecting protein degradation. Although it is often believed that the
effects of GH are mediated through IGF-1, this cannot be the case
entirely. First, the effects of the two hormones are different, in that
GH does not change protein degradation. Second,the effect of GH is
observed with little or no change in systemic IGF-1concentrations. Age
related muscle loss has been prevented with GH injections,however it is
believed that this is accomplished through IGF-1.
