Morphological characterization of lymphoid cells conjugates with scattered tumor target cells in organ imprints of Yoshida ascites bearing rats.
The authors analysed morphologically the ability of host effector cells to bind disseminated tumor target cells (pre-lysis) in vivo. Scattered tumor cells are morphologically visible stained with May Grünwald-Giemsa in the lung, liver, kidney, and spleen imprints of Yoshida ascites tumor bearing rats. Lymphoid cells can be seen binding disseminated tumor target cells in organs but not in the peritoneal cavity. This model may provide a useful technique for morphological studies on the in vivo conjugation capacity of host effector cells against tumor target cells.
