ULTRASTRUCTURAL STUDY OF THE THYMUS OF THE NEONATAL MOUSE / 解剖学报

ABSTRACT

With light and electron microscope, we studied the morphology of the thymus of the neonatal mouse. The results showed 1.the lobules of the thymus had not well developed and there was no distinct demarcation between the cortex and medulla; 2.a cyst composed of epithelial cells with microvilli or cilia might be frequently seen in the medulla; 3.occasionally small lymphocytes with some glycogen particles in their cytoplasm were observed; 4.only a few small-sized thymic corpusles existed in the medulla, The article also described the ultrastructure of the lymphocytes, epithelial reticular cells, macrophage, interdigitating cell and blood-thymus barrier in the thymus of the neonatal mouse.
