The Endocrine Regulation of Chicken Growth
The somatotropic axis plays a key role in proliferation and differentiation of avian organs during both preand posthatching periods. This review discusses the complexity of regulation of the endocrine system for chicken development and growth by growth hormone (GH), insulin-like growth factor (IGF), and IGF binding protein (IGFBP). In addition, the thyrotropic axis, including thyrotropin-releas...
متن کاملEndocrine regulation of the growth plate.
Longitudinal bone growth occurs at the growth plate by endochondral ossification. Within the growth plate, chondrocyte proliferation, hypertrophy, and cartilage matrix secretion result in chondrogenesis. The newly formed cartilage is invaded by blood vessels and bone cells that remodel the newly formed cartilage into bone tissue. This process of longitudinal bone growth is governed by a complex...
متن کاملEndocrine Regulation of Compensatory Growth in Fish
Compensatory growth (CG) is a period of accelerated growth that occurs following the alleviation of growth-stunting conditions during which an organism can make up for lost growth opportunity and potentially catch up in size with non-stunted cohorts. Fish show a particularly robust capacity for the response and have been the focus of numerous studies that demonstrate their ability to compensate...
متن کاملEndocrine regulation of longitudinal bone growth.
Longitudinal growth is primarily influenced by the GH-IGF-I axis, which is a mixed endocrine-paracrine-autocrine system. Further, classical hormones such as thyroxine, glucocorticosteroids and sex steroids play a role, as well as primarily paracrine systems. In the GH-IGF-I axis, seven disorders can be differentiated: (1) GH deficiency; (2) GHR defects; (3) defects in the GH signal transduction...
متن کاملEndocrine regulation of feto-placental growth.
Hormones are both growth stimulatory and growth inhibitory in utero. They regulate tissue growth and development by controlling the rates of cell proliferation, apoptosis and differentiation in many fetal tissues. They also signal the level of resources available for intrauterine growth to the fetal tissues and relay back to the placenta the degree of mismatch between the actual fetal nutrient ...
