Does gravity actually influence the direction myofibrils grow? Such as, does gravity influence the direction satellite cells 'congregate' when moving in to repair the damaged (just worked) area of muscle? Basically does gravity hinder the satellite cells from moving to the 'top' of the fiber, when healing and growing, and therefore hinders the fiber from growing more upwards then if 'grown' in zero gravity? How do we know fibers don't significantly grow just down towards the grownd... but b/c of the tendon it can 'push off' as it grows, allowing it grow upwards too?
