WebNov 17, 2014 · Cytoplasmic vacuolization ( Figure 1 and Figure 2) manifests as increased cell size and volume resulting from an overload of fluid caused by a failure of the cell to maintain normal homeostasis and regulate the ingress and excretion of fluid. Histologically, cells are enlarged and the cytoplasm of affected cells contains translucent vacuoles. WebAbstract. Vacuoles and their mammalian counterparts, lysosomes, are membrane-bound cytoplasmic organelles that contain an assortment of soluble acid-dependent hydrolases and a set of highly glycosylated integral membrane proteins. Most notably, this organelle is an important site for the degradation of cellular lipids, membrane-associated ...
