Prenatal changes in the neurotransmitter/neuromodulator profiles of ty
rosine hydroxylase (for dopamine), substance P, neuropeptide Y, and le
ucine-enkephalin were studied in developing human retinal amacrine cel
ls by the use of immunohistochemical techniques. Tyrosine hydroxylase
was localized between 10 and 12 weeks of gestation, substance P and ne
uropeptide Y appeared little later around 14 weeks, and leucine-enkeph
alin-like immunoreactivity was observed at 16 weeks.
