Ultrastructure Features of Coronary Artery Endothelium in Bactrian Camel (Camelus bactrianus)

Abstract

SUMMARY:Vascular endothelium play an essential role in regulating endothelial functions by maintaining normal vascular tone, modulating hemostasis, and preventing thromobogenesis. The aim of present study was to reveal ultrastructure features of coronary artery endothelium in Bactrian Camels by means of scanning electron microscope (SEM) technology. The results showed that the endothelial cells distribute along the direction of blood flow. Their morphology and protuberant degree towards luminal surface vary for different parts of the coronary artery. The luminal surface of a.c oronaria sinistra and a. coronaria dextra was covered by impaired and intact endothelium, respectively. Platelets and leukocytes sticking to the endothelium were found.

Multiscale three-dimensional surface reconstruction and surface roughness of porcine left anterior descending coronary arteries

“…Multiscale measurement is important to replicate physiological function. Other studies have qualitatively assessed the dehydrated surface of coronary arteries using SEM [35,36], and they have also investigated hydrated samples using scanning force microscopy [35]. Endothelial cells were noted to be aligned longitudinally, as they were within this study, causing ridges along the sample surface [37].…”
