Abstract：
:Intact rod photoreceptors were dissociated from pronase-treated whole retinas of adult mice by repeated passage through a plastic pipette tip. Hemocytometer counts of the cell suspensions indicate that, during a series of ten dissociation steps, a total of about 1-2 million intact photoreceptor cells are dissociated from one adult mouse retina, with less than 5% contamination from Müller cells and neurons of the inner retina. Visual cells with rod outer segments (ROS) and synaptic terminals are released in each step, but they occur in the greatest number during the sixth to ninth steps; detached ROS are released most frequently in the early steps, and neurons of the inner retinal layers appear in the later steps of dissociation. Nuclei are found in each step. Cell intactness was estimated by Trypan blue and Erythrosin B exclusion and by microscopic analysis using differential interference optics or scanning electron microscopy. The cells bind lectins (concanavalin A, Ricinis communis, and wheat germ agglutinin but not peanut agglutinin), displaying surface topography like that observed in situ. The metabolic capacity of dissociated cells was assessed by measuring the utilization of 32P inorganic phosphate for the synthesis of phospholipids and for the light-dependent phosphorylation of rhodopsin. Mature photoreceptor cells were estimated to contain, on average, 6.4 X 10(-12) g DNA, 2.3 X 10(-12) g RNA and 42-64 X 10(-12) g protein. The dissociation procedure provides a population of photoreceptor cells that appears suitable for microscopic, electrophysiological, and biochemical analysis.
