The appearance and accumulation of apolipoprotein B and unesterified cholesterol in the lesion-prone areas of the aorta in rabbits with diet-induced hyperlipidemia were investigated by histo-, and cytochemical techniques. Apolipoprotein B was detected by an indirect immunoperoxidase procedure both in the light and electron microscopy. Unesterified cholesterol was revealed using filipin and tomatine as specific probes. In the prelesional stages of atherogenesis, before the appearance of any structurally detectable lesions, as demonstrated by bright-field and fluorescence microscopy, apolipoprotein B and free cholesterol accumulated progressively in the extracellular matrix of the subendothelial space. At ultrastructural level, extracellular phospholipid liposomes, unesterified cholesterol and apolipoprotein B concomitantly appeared and accumulated focally in the same areas. Apolipoprotein B was preferentially located on the outer surface of the free cholesterol-containing phospholipid lamellae of the extracellular liposomes. In the lesional stages leading to fatty streak formation, the extracellular liposomes, apolipoprotein B and unesterified cholesterol had also topographically a superimposed localization pattern. Intracellular apolipoprotein B and unesterified cholesterol were also colocalized in some intimal lipid-laden cells. In the prelesional stages of hyperlipidemia the prevalent localization of apolipoprotein B around individual unesterified cholesterol-rich extracellular phospholipid liposomes, progressively accumulating in the subendothelial space, suggests their possible origin from serum-derived lipoproteins.
