Metabolic properties of freshly isolated bovine endothelial cells.


Studies on endothelial cells metabolism have been limited by the lack of availability of a procedure for obtaining such cells in quantities adequate for direct in vitro analysis. Viable and well-dispersed endothelial cells in high yield have been obtained from the cavernous bodies of bovine penis. A preliminary characterization of the metabolic properties of the isolated cells has concerned the respiratory activity and some aspects of the carbohydrate metabolism. This study points out the following metabolic characteristics of endothelial cells: (1) a low respiration that is inhibited by high glucose concentrations (Crabtree effect); (2) a very high glycolytic activity in aerobic conditions, with a low Pasteur effect; (3) a very high potential activity of the hexose monophosphate shunt relative to the actual flux in the pathway. The biological relevance of these observations is discussed.
