英文摘要	Glycocalyx is located outside the vascular endothelial cells playing an important role in vascular homeostasis. However, lacking efficient detection methods is one of the biggest obstacles to study the glycocalyx. In this study, three dehydration methods were used to compare the preservation of HUVEC, aorta and kidney glycocalyx by transmission electron microscope. The chemical pre -fixation was performed by lanthanum nitrate staining, and the mice aorta and renal glycocalyx were prepared by different dehydration methods such as ethanol gradient, acetone gradient and low temperature dehydration. HUVEC glycocalyx was prepared by acetone gradient and low temperature dehydration. Low temperature dehydration method preserves HUVEC and mice aortic glycocalyx completely, which had a certain thickness and presented a needle-like structure. But for mice kidney, the acetone gradient dehydration preparation method could better preserve the glycocalyx integrity than other two methods. In conclusion, low temperature dehydration method is suitable for HUVEC and aortic glycocalyx preservation, acetone gradient dehydration method is more suitable for kidney glycocalyx preservation.
