Objectives:
To improve the culturing method of pulmonary microvascular endothelial cells (PMEVCs) of SD rats.
Methods:
The culturing processes in regard to obtaining peripheral lung tissue, attaching tissue block,preparing medium and subculturing were modified.These included an injection of heparin sodium before anesthesia, abdominal bleeding, opening of chest when breathing stopped, improvement of operational details, reduction of pollution by adding penicillin and streptomycin, discard of tissues after 48 h of primary culturing, remove of fibroblasts by a second digestion, and identification of cells using a fluorescence microscope for binding with lectin from BSI (FITC-BSI).An inverted microscope was used to observe the morphological characteristics of PMEVCs.
Results:
Purified PMEVCs were obtained,which displayed a polygon or short fusiform, exhibiting a typical cobblestone-like morphology. The morphology of PMVECs turned into swirling or long fusiform following subculture or changes in culture conditions. The results of FITC-BSI assay showed that more than 90% cells were stained with green fluorescence.
Conclusions:
Purified PMEVCs with a good growth state and subculture stability can be obtained using the modified method.
