| Modification Notes |
Various hormones are secreted from the anterior pituitary during development and growth, including prolactin, lutropin (LH), thyroid-stimulating hormone (TSH) and the Proliferins. In rodents, there are four Proliferin proteins, designated Proliferin-1, Proliferin-2, Proliferin-3 and Proliferin-4, all of which are secreted and are thought to play a role in embryonic development. More specifically, the Proliferins provide a growth signals to target cells in fetal and maternal tissues during the mid-gestation phase of embryogenesis. |
