Human aortic endothelial cells (HAECs), human vascular smooth muscle cells (HVSMCs), and human brain vascular adventitial fibroblasts (HBVAFs) were bought from ATCC (Virginia, America). HAECs were cultured in endothelial cell medium, while HVSMCs and HBVAFs were cultured in DMEM and MEM medium, respectively, supplemented with 10% FBS and 1% penicillin‐streptomycin. All cell culture media and reagents were purchased from Gibco (California, America).
The viability of HAECs was assessed using a cell counting kit‐8 (CCK‐8) (KeyGEN Biotechnology, Jiangsu, China). After 24 h of attachment, HAECs were divided into five groups: PBS, H2O2 (100 µM), H2O2 + Cur (25 µM), H2O2 + NO‐Gel (NO donor, 75 µM), and H2O2 + Cur‐NO‐Gel (Cur concentration, 25 µM), and incubated for 24 h. β‐galactosidase was added to all culture media containing NO donor at a dose of 0.2 U mL−1. Then, the cells were incubated with CCK‐8 assay buffer and detected using a microplate reader (Bio‐RAD iMark™, California, America). The viability of HVSMCs and HBVAFs was evaluated using a similar approach.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
