Figure 1. Cholestatrienol low density lipoprotein uptake by the rat retina
Vibrotome sections of rat retina imaged by confocal microscopy after intravenous injection with the fluorescent cholesterol analog cholestatrienol (CTL; blue) complexed with human low density lipoprotein (LDL). Rats were injected with 2 mg of cholestatrienol-low density lipoprotein (CTL-LDL) and sacrificed at different time intervals. The nuclei were stained with propidium iodide (red) and the capillaries were stained with Alexa 488®-conjugated isolectin IB4 (green). A and B: 2 h post-injection; C and D: 4 h post-injection; E and F: 6 h post-injection; G and H: 24 h post-injection. Arrow points to LDL deposit remaining in the choroid after 24 h.
