人脐静脉内皮细胞的培养和连续传代 [PDF]

Zhongshan Daxue xuebao. Yixue kexue ban, 1993
本实验用新生小牛视网膜提取物作血管内皮细胞生长促进剂,成功地使人脐静脉内皮细胞在体外连续培养23代以上。细胞倍增时间平均为16.6h,细胞传代时间平均为5 d,传代比率为1:2～1:3。用ABC法证明细胞内存在Ⅷ因子相关抗原(FⅧr-Ag),透射电镜下可见胞浆内含WP(Weibe1-Palade)小体,证实所培养的细胞为血管内皮细胞。

Fatty acid β‐oxidation and mitochondrial fusion are involved in cardiac microvascular endothelial cell protection induced by glucagon receptor antagonism in diabetic mice 脂肪酸β‐氧化和线粒体融合参与胰高血糖素受体拮抗剂对糖尿病小鼠心脏微血管内皮细胞的保护作用

Journal of Diabetes, Volume 15, Issue 12, Page 1081-1094, December 2023., 2023
Highlights Glucagon receptor (GCGR) monoclonal antibody (mAb) improves cardiac function and attenuates microvascular damage in db/db mice. GCGR mAb ameliorates the oxidative stress of cardiac microvascular endothelial cells in diabetic mice. GCGR mAb counteracts the diabetes‐induced upregulation of carnitine palmitoyltransferase 1B, optic atrophy type ...

Effects of SGLT2 inhibitors on patients with diabetic kidney disease: A preliminary study on the basis of podocyturia SGLT2抑制剂对糖尿病肾病患者的影响:基于尿足细胞的初步研究

Journal of Diabetes, Volume 14, Issue 4, Page 236-246, April 2022., 2022
Highlights Diabetic kidney disease is a progressive disease with the pathology of glomerular damage and loss of podocytes. Sodium glucose cotransporter 2 inhibitors (SGLT2i) can be expected to decrease the amount of podocyte excretion. Male patients receiving SGLT2i have better diabetic kidney disease‐related parameters and podocyturia levels. Abstract
