Abstract
Twenty‐five human hematopoietic cell lines established from patients with malignant and non‐malignant diseases have been studied for membrane fluidity. The degree of fluidity in the surface membranes was quantitatively monitored by fluorescence polarization analysis of the fluorescence probe, 1,6‐diphenyl 1,3,5‐hexatriene, when embedded in the lipid region of the surface membrane of intact cells. The results have shown that cells derived from malignant diseases have a more fluid lipid layer in their surface membrane than cells derived from non‐malignant disorders. It is, therefore, suggested that a quantitative analysis of fluidity differences in the cell surface membrane lipid core can be of value to the studies on basic differences between normal and malignant cell lines established from the human hematopoietic system.

The activity of ecto-nucleotidases has been determined on intact cells from Burkitt lymphoma (BL) and lymphoblastoid cell lines established in vitro (LCLs). BL cells never express ecto-5'-nucleotidase (5'-N) and exhibit only low levels of ecto-ATPase activity, whereas LCL-cells usually express both
## Abstract Binding sites for Concanavalin A (Con A) can move on the surface membrane. This induction of movement resulted in the formation of caps of Con A membrane‐site complexes in normal lymph‐node or spleen lymphocytes, but not in a line of malignant lymphoma cells. This indicates a difference
