H and E staining of tumor and the associated infiltrated organs in a mouse.

<p>Histological images of (<b>A</b>) tumor, (<b>B</b>) liver, (<b>C</b>) GI tract and (<b>D</b>) pancreas from a mouse injected i.p. with NAD cells (5×10⁶). Arrows in the tumor (<b>A</b>) indicate pockets of tumor cells surrounded by connective tissue. (<b>B–D</b>) arrows indicate tumor cells invading the respective organs. H and E staining of (<b>E</b>) kidney and (<b>F</b>) ovary from a mouse injected with NAD cells (5×10⁶). Arrows indicate tumor cells surrounding the organs without invasion. Magnification was 200× for all, except ovary which had magnification of 100×, scale bar = 50 µm.
