Haematoxylin and eosin. Thymuses from 18 day-old embryos. (a) Normal thymus. (b) The medullary clusters are made up of epithelial cells, some have cystic appearance of the intra-or intercellular type. (c) PD thymus. The size is clearly reduced. (d) PD thymus. In the medulla no clusters of epithelial cells are present. (e) PD+H thymus. The cortex (C) is similar to that of normal thymus and there is an improvement of the medullary zone (M). (f) In the medulla the epithelial clusters are present (arrow) without reaching the number of the normal thymus. (g) PD+Th thymus. Note the good recovery of the total size. (h) PD+Th thymus. Good improvement of the epithelial cluster in the medulla (arrow). Scale bar: a,c,e,g: 100 µm; b,d,h: 40 µm; f: 25 µm.
