NettetThe GH/IGF axis, acting in an endocrine and autocrine/paracrine fashion, is the major axis controlling skeletal growth. Studies in rodents have clearly shown that IGFs regulate bone length of the appendicular skeleton evidenced by changes in chondrocytes of the proliferative and hypertrophic zones of the growth plate. NettetThe anabolic role of growth hormone (GH) in long bones is well accepted. The relative contributions of GH acting on the liver (increasing growth promoting endocrine factors) or directly (on growth plate cartilage) however remain unclear (Lupu et al., 2001).It is likely that both these modes of GH action function in a highly coordinated manner to regulate …
