Analysis of morphology and apoptosis in the thymus of tumor-bearing C57BL/6 +/+ mice.

Section of thymus from PBS-injected control (A, B) or LSA tumor-bearing (C, D) or EL-4-tumor bearing (E, F) mice were examined after H&E staining (A, C, E) or TUNEL assay to detect apoptosis (B, D, F). More tumor cell infiltration was observed in the thymus than in the liver.
