© 2022 British Poultry Science Ltd.1. The epidermal growth factor (EGF) family plays an important role in the development, differentiation, migration and apoptosis of cells, as well as in wound healing, which are all essential to the viability of multicellular organisms. The avian spleen is a principal organ of systemic immunity and its importance in disease resistance is presumably accentuated by the scarcity of avian lymph nodes. 2. The aim of this study was to determine whether EGF receptors (ErbB1-4) and their ligands (EGF, AREG and NRG) are expressed in the structural components of the quail spleen during the post-hatch period. At each selected age, from 1 d to 7, 14, 21 and 60 d, 10 quails were euthanised under ether anaesthesia and their spleens were fixed in a 10% formaldehyde-alcohol solution. Following routine histological processing, the streptavidin-biotin-peroxidase method was used for immunohistochemical examination. 3. Strong cytoplasmic immunoreactions for ErbB2, ErbB4 and NRG were observed in the ellipsoid associated cells (EAC) of the quail spleen throughout the post-hatch period. This immunoreactivity in the EAC increased after the 7th d post-hatch. ErbB1 and ErbB3 immunoreactions were relatively similar and weak in all components of the spleen during the post-hatch period. Some immune cells of the peri-arterial lymphatic sheath (PALS) and peri-ellipsoidal lymphatic sheath (PELS) showed positive immunoreactivity for the ErbB receptors and their ligands. In the vascular smooth muscle cells, immunoreactivity for ErbB2 was stronger than that for the other ErbB receptors and their ligands. 4. The data showed that ErbB receptors and their ligands (EGF, AREG and NRG) are expressed by different structural components of the quail spleen during the post-hatch period.
