Morphological characteristics of the ICAs in the four groups. (a) and (b) Normal ICA with uniform thickness, regular fiber arrangement, and complete structure of tunica adventitia, media, and intima in the Non-CRM-Normal group and CRM-Normal group; (c) atherosclerotic ICA with slightly thickened intima (red arrows), edematous cells, thinly stained cytoplasm, and disordered cells arrangement (black arrows) in the Non-CRM-Model group; (d) atherosclerotic ICA with severe thickened and atherosclerotic intima, disordered fiber arrangement, and infiltration of foam cell (black arrows) and the calcified lesion at the junction between the tunica adventitia and tunica media (blue arrows) in the CRM-Model group.
