ALNA of Bactrian camel fetus at 13 months of gestation. b The mucosal folds of ALNA (yellow oval area) increased and thickened, and developed rapidly. b The lymphoid follicles were enlarged in volume and covered by FAE, forming a typical SED structure. H&E stain, Scale bar 200 μm. c FAE cells are mainly cuboidal epithelial cells (black arrows), with some intraepithelial lymphocytes (red arrows) scattered between them, while non-FAE cells are mainly monolayer columnar epithelium (yellow arrows). H&E stain, Scale bar 20 μm. d The primitive interfollicular area is formed between lymphoid follicles, which contains HEVs (black arrows). H&E stain, Scale bar 20 μm
