OBJECTIVE: To study the expression pattern of calcitonin gene-related peptide (CGRP)-like immunoreactivity (-ir) in the duck thymus during the embryonic and postembryonic development. STUDY DESIGN: Studies were carried out on Tianfu ducks on 12, 14, 16, 18, 20, 22, 24, and 26 days of age prehatching, and at 0 (hatching), 1, 3, 5, 8, 14, 17, 20, 26, 29, and 32 weeks of age posthatching using high-sensitivity immunocytochemistry. RESULTS: CGRP-ir was detected in the neuron-like cells, the lymphocytes, the vascular smooth muscle cells, as well as the reticular epithelial cells of Hassall's corpuscle and diffuse forms of Hassall's corpuscle...
