Objective:
To establish an improved method for culturing primary mouse pulmonary microvascular endothelial cells (PMVECs).
Methods:
An improved tissue block adherent culture method was used to isolate and culture the PMVECs from C57 mice. The cultured cells were identified by factor VIII-related antigen and CD31 antigen, and the growth of cells cultured using the improved method and the conventional method was compared.
Results:
The cultured primary pulmonary microvascular endothelial cells showed a short fusiform or round morphology, and the cell monolayer displayed a cobble stone-like appearance. The cultured cells were positive for VIII-related antigen and CD31 antigen. The cell growth was accelerated in the cell cultures with the improved method compared with that in conventional cell cultures.
Conclusion:
The improved culture method allows more efficient acquisition of primary mouse PMVECs of a greater purity.
