Ultrastructural effects of colchicine on perikarya and initial segment of rat retinal ganglion cells.


Our ultrastructural study was focused on the perikaryal region and initial segment of the axon of rat retinal ganglion cells in controls and after intraocular injections of colchicine. In control rats that region contained, among other organelles, elements of the Golgi complex and, close to them, short isolated microtubules oriented preferentially toward… (More)
