Ultrastructure of the granulopoietic microenvironment in the tunica propria of the bursa of Fabricius of white Leghorn chicken embryo.
Granulopoietic areas of tunica propria of chicken embryo bursa (stage 38 to 45 H-H) were composed of fibroblasts, reticular cells with and without lipid droplets and macrophages within a network of collagen fibers. We suggest that the reticular cells with lipid droplets could have the same microenvironmental significance as adipocytes of other granulopoietic organs.
