Contrasting modulation by transforming growth factor-beta-1 of insulin-like growth factor-I production in osteoblasts and chondrocytes.

abstract：:gamma-Aminobutyric acid (GABA) inhibits the embryonic migration of GnRH neurons and regulates hypothalamic GnRH release. A subset of GnRH neurons expresses GABA along their migratory route in the nasal compartment before entering the brain, suggesting that GABA produced by GnRH neurons may help regulate the migratory ...
