Thyroid hormones in fetal growth and prepartum maturation.
The thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are essential for normal growth and development of the fetus. Their bioavailability in utero depends on development of the fetal hypothalamic-pituitary-thyroid gland axis and the abundance of thyroid hormone transporters and deiodinases that influence tissue levels of bioactive hormone. Fetal T4 and T3 concentrations are also affec...
متن کاملPlacental hormones and the control of fetal growth
Linear growth in the postnatal period is controlled by the production, secretion, and action of pituitary growth hormone and IGF-1. IGF-I and IGF-II production and signaling are also essential for fetal growth and neural development. But the control of IGF production in the fetus is largely independent of GH. Among the factors that control fetal IGF production, the availability and utilization ...
متن کاملFetal and Postnatal Cellular Growth: Hormones and Nutrition
Dr. Donald Cheek has been interested in body growth and composition for many years and in 1968 published Human Growth. To gain information specifically about fetal growth and immediate postnatal growth Dr. Cheek turned to a primate, Macaca mulatta. A series of extensive and rigorous investigations on prenatal growth, especially of the brain, has been performed by Dr. Cheek and his many collabor...
متن کاملThyroid Hormones and Fetal Development
The importance of thyroid hormones for normal fetal development is well established. Through animal experiments (1,2) and clinical studies (3,4), thyroid hormones have been clearly found to be crucial in brain development, maturation, and normal function. The fetal thyroid begins to produce thyroid hormones at about 10 to 12 weeks of gestation. During the first trimester, thyroid hormones are s...
متن کاملThyroid hormones and fetal neurological development.
The development of fetal thyroid function is dependent on the embryogenesis, differentiation, and maturation of the thyroid gland. This is coupled with evolution of the hypothalamic-pituitary-thyroid axis and thyroid hormone metabolism, resulting in the regulation of thyroid hormone action, production, and secretion. Throughout gestation there is a steady supply of maternal thyroxine (T(4)) whi...
