H&E- and TUNEL-stained images of tumour tissue sections from xenograft-bearing mice receiving different treatments after 18 days of treatment. H&E assay results revealed blue staining of the cell nuclei and red staining of the cytoplasmic and extracellular matrix. TUNEL assay analysis showed that the brown staining of the cell nuclei indicated apoptosis- and proliferation-positive tumour cells, whereas blue staining of the cell nuclei indicated apoptosis- and proliferation-negative tumour cells.
