where do stem and satelite cells hang out?

[skull]

just want to know where in the body do stem/sat cells stay dormant in the body in relation to site specific growth?If I take AAS and it causes muscle growth to happen,the new muscle will be made from stem/sat cells -so are those cells everywhere in the body or do they travel to repair muscle where needed?Theres a report in the IGFsection that says if you use t3 while on AAS or IGF that the t3 will go after the cells that cause muscle growth and I was wondering if it realates to systemic or site specific?

Don't they lay dormant in the outer layer of muscle fibers?

Don't they lay dormant in the outer layer of muscle fibers?

so your saying there in all muscles equally thruout?

just want to know where in the body do stem/sat cells stay dormant in the body in relation to site specific growth?If I take anabolic steroids and it causes muscle growth to happen,the new muscle will be made from stem/sat cells -so are those cells everywhere in the body or do they travel to repair muscle where needed?Theres a report in the IGFsection that says if you use t3 while on AAS or IGF that the t3 will go after the cells that cause muscle growth and I was wondering if it realates to systemic or site specific?

actually from what we know most of steroids' muscle building effects come from stimulation of intracellular igf-1 stimulation (not the systemic version we take), direct stimulation of protein synthesis by the steroid/recptor complex recruiting ribosomes after DNA expression, and an upreguation of satellite cell activity.

most people will just tell you "steroids increase protein synthesis", and its a little more complex than that. when you factor in the increased satellite cell activity and the upregulation of intracellular igf-1 the possibility of steroids creating new muscle cells over time doesnt sound to brotelligent.
