A remarkable projection of bleblike protrusions, the expulsion of organelles into the protrusions formed on the apical surface, and the separation into the ventricular lumen of these protrusions was the general cellular response of choroidal epithelial cells to intravenous injection of cytochalasin D (CD). The compact microfilament mass and agglomeration of microtubules at the base of the cluster of protrusions reflect the results of cell contraction and displacement of microfilaments induced by CD. In earlier stages after intravenous injections of colchicine, an obvious increase in the number of various-sized vesicles, vacuoles, and lysosomes in the Golgi region was detected. In the later stages, these organelles were seen to accumulate in the basal portion of the epithelial cells. These changes were accompanied by an increase in vacuoles and the disorganization and displacement of the Golgi complex, and they coincided with a decrease in the number of microtubules in apical and basal cytoplasm. These findings suggest that the action of colchicine results in destruction of the three-dimensional architecture between cytoskeletal network and cell organelles. The present results suggest that the cytoskeletal network plays a role in the spatial coordination of the three-dimensional architecture of cell organelles. The study also indicates that the structural differences in the ventricles of the choroid plexus in drug-treated pigeons are manifestations of regional functional specialization in different parts of the ventricular system.
