title: The effect of cortisol on gamma-glutamyl transpeptidase activity in the glycogen body and lumbosacral segments of developing chick spinal cord.
abstract: Gamma-glutamyl transpeptidase (GGT) activity is heterogeneously distributed between the lumbosacral chick spinal cord and the adjacent glycogen body during late embryonic and early posthatch development and displays hormonal sensitivity. As GGT activity may reflect the cellular transport of some amino acids, the transiently high activity of this enzyme in the glycogen body suggests that these cells play an important role in amino acid transport and metabolism at a time coincident with the initial phase of myelination in the embryonic chick spinal cord.
