Vascular Structure of Experimental Tumours: Appearances in scanning electron microscope

Abstract
The vascular structure of experimental tumors [mouse Ehrlich ascites carcinoma cells, ascites hepatoma 7974 cells and ascites hepatoma 109A cells] was investigated by a resin cast technique. Six characteristic types of capillaries were found: club-like, wave-like, tortuous, sinusoid-like, disorderly running and tapering. The vascular structure was correlated to the tumor growth.
