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): TSH stimulates the thyroid gland to produce hormones. The posterior lobe contains the ends of nerve cells coming from the hypothalamus. The hypothalamus sends hormones directly to the posterior lobe via these nerves, and then the pituitary gland releases them.
