Before and after hatching, J-chain-positive cells (JPC) were observed by immunoelectron microscopy in lymphoid tissues from chickens that had been chemically bursectomized (Bx) in ovo. These JPC were detected in spleens both of normal and Bx birds. Subcellular localization of J chains showed more variations in normal than Bx chickens. From these findings, JPC could be divided into JPC subpopulations in chickens.
