Temporal expression of avian β defensin 10 and cathelicidins in the yolk sac tissue of broiler and layer embryos.

ABSTRACT: The yolk sac is a multifunctional organ, which not only participates in nutrient absorption, but also plays an important role in immune function. The objective of this study was to compare the mRNA abundance of avian β-defensin 10 (AvBD10) and 3 cathelicidins (CATH1, CATH2, and CATH3) in the yolk sac tissue (YST) of commercial broilers and white egg and brown egg commercial layers. AvBD10 and CATH mRNA abundance was analyzed using two-way ANOVA and Tukey's test, with P < 0.05 being considered significant. AvBD10 and CATH mRNA showed similar temporal expression patterns in the YST of both broiler and layers, with an increase from embryonic day (E) 7 to E9 through E13 followed by a decrease to day of hatch. AvBD10 mRNA showed a breed × age interaction with greater expression in the YST of bo
