Immunohistochemical localization of tyrosine hydroxylase, substance P, neuropeptide-Y and leucine-enkephalin in developing human retinal amacrine cells.
Prenatal changes in the neurotransmitter/neuromodulator profiles of tyrosine hydroxylase (for dopamine), substance P, neuropeptide Y, and leucine-enkephalin were studied in developing human retinal amacrine cells by the use of immunohistochemical techniques. Tyrosine hydroxylase was localized between 10 and 12 weeks of gestation, substance P and neuropeptide Y appeared little later around 14 weeks, and leucine-enkephalin-like immunoreactivity was observed at 16 weeks.
