FIG. 1.
Histology of HCMV-infected human thymus-liver implants. The human thymus-liver implants in SCID mice were uninfected (A and B) or inoculated with either AD169 (C and D), Toledo (E and F), or ToledoBAC (G and H). After 13 days, the tissues were collected, processed, and stained with hematoxylin and eosin. Intact T cells in the thymus lobes appeared dark blue (A to D) due to hematoxylin uptake by the nuclei, and necrotic areas appeared red (E to G) from eosin staining of protein. The right panel shows a higher magnification (×98) than the left panel (×19.6) of the area within the outlined blue box of the same section.
