Interaction in culture between mouse ascites hepatoma (MH-134) cells and lymphoid cells of isologous mice. 1975

H Katsuta, and K Ashikawa, and T Takaoka

Thymocytes or lymphocytes of mesenteric lymph nodes were obtained from mice bearing subcutaneously mouse ascites hepatoma MH-134 for 5 to 40 days. These lymphoid cells were added into the cultures of MH-134 cells. Morphological changes of cells in the mixed cultures were observed by time-lapse cinemicrography for the period of 4 weeks. Lymphoid cells were phagocytosed by MH-134 cells, and, in most cases, the tumor cells did not undergo any damage due to the phagocytosis. The exceptional cases were as follows: When MH-134 cells were mixed with thymocytes from mice bearing MH-134 tumor for 5 days, MH-134 cells phagocytosed thymocytes but some of them died later. In the mixed cultures of MH-134 cells and thymocytes or mesenteric lymph node lymphocytes from mice bearing MH-134 for 14 or 15 days, MH-134 cells phagocytosed lymphoid cells but died later by the burst of cytoplasm. By the burst many lymphoid cells phagocytosed appeared from the broken cytoplasm of MH-134 cells and, in some cases, the lymphoid cells looked to be alive. These findings suggest the possibility that lymphoid cells attack tumor cells not only from the cell surface but also from the inside being phagocytosed by tumor cells.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D006528	Carcinoma, Hepatocellular	A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
