The mesothelial origin of epididymal adenomatoid tumor is supported by the current study for the presence of mesothelial antigen in the tumor cells. By an indirect immunoperoxidase technique, anti-mesothelial cell serum showed positive cytoplasmic staining in five of the six adenomatoid tumors studied. Previous findings of the presence of strong cytoplasmic keratin and the absence of carcinoembryonic antigen and Factor VIII-related antigen in these tumor cells are also confirmed by this study.

Endothelial cells from rat epididymal fat pad capillaries were isolated from rats immediately after weaning. The cells were obtained after an initial brief incubation with collagenase under conditions of minimal breakage of cells. Adipocytes were removed by flotation and endothelial cells were then obtained as cell aggregates by fractional filtration procedures whereby intact tissue as well as free cells were removed. These aggregates were then dispersed and cultured in supplemented medium 199 whereby a monolayer of cells with a growth pattern, numerous pinocytotic vesicles, and intercellular junctions typical of endothelial cells were obtained. Minor contaminations of precursor cells to adipocytes were absent after one subculture. Here greater than 95% of the cells showed the presence of Factor VIII. Further subcultures produced nonhomogenous cells and decreasing rates of replication. The endothelial cells showed a very low rate of triglyceride synthesis and release, and collected no visible lipid upon prolonged cultures in the presence of an abundance of triglyceride substrate. They bound lipoprotein lipase from rat adipocytes, whereby the lipase was stabilized. This binding was released by heparin, and the cells did not synthesize the enzyme.

Rat KMT-17 fibrosarcoma-derived endothelial cells were isolated by Percoll gradient centrifugation with an attaching-speed separation technique, and their properties in culture were examined. The primary cultured tumor-derived endothelial cells (TEC) showed angiotensin-converting enzyme activity, positivity for Factor VIII-related antigen staining, and typical capillary-like formation on Matrigel. The primary cultured TEC monolayer showed greater permeability than normal tissue-derived endothelial cell (aorta, vena cava and epididymal fat capillary) monolayers on FITC-dextran diffusion (molecular weight 70,000). Leukocyte adhesion to TEC was reduced compared to that to fat-derived capillary endothelial cells. These characteristics resembled those of tumor vascular endothelium, and were observed both in the primary and first-passage cell cultures, but not in the fourth-passage cell cultures. Our findings indicate that primary or subcultured TEC are applicable for studies of the physiological characteristics of tumor endothelial cells.
