Colquhounia Root Tablet Protects Rat Pulmonary Microvascular Endothelial Cells against TNF--Induced Injury by Upregulating the Expression of Tight Junction Proteins Claudin-5 and ZO-1

Figure 3

CRT alleviated the TNF--induced cell injury. Rat PMEC monolayers were divided into 6 groups: normal control (a), TNF-α (b), Dex (c), CRT high (d), CRT medium (e), and CRT low groups (f). After 48 h incubation, intracellular microstructures were observed under an H7650 transmission electron microscope (20000). Arrows and triangles mark the mitochondria and endoplasmic reticulum, respectively.
