Then there are the actual studies performed on pregnant women and new mothers, which are ambiguous. Some show memory impairments, especially toward the end of pregnancy, when (psychologists theorize) the brain undergoes a process of neural reprogramming as it prepares to nurture the new baby.
At present it is unknown whether these effects are due to direct effects of growth hormone on hematopoietic cells or if they are caused by the induction of insulin-like growth factor-1 (IGF-1) synthesis.n support of the second possibility, we have induced apoptosis of both nonadherent bone marrow cells and a myeloid progenitor cell line by depriving these cells of CSFs. Preliminary results indicate that addition of IGF-1 to these cells reduces apoptotic cell death by 50%.
Thyroid-stimulating hormone (TSH) is produced by the adenohypophysis. It promotes development of the thyroid gland and maintenance of its normal function. TSH stimulates the thyroid to produce and release the thyroid hormones: T4 and T3 (hypothalamus-pituitary-thyroid axis). Measurement of TSH frequently is included with that of T4 and T3 in a laboratory panel to screen for and to evaluate thyroid disease.
