Abstract:
Objective To establish a method for culture of rat pulmonary capillary pericytes.Methods Six male Sprague-Dawley rats,aged 6-7 weeks,weighing 200-220 g,were anesthetized and the chest was opened.The pulmonary capillary was isolated by type Ⅰ collagenase digestion and micropore filtration and cultured in highglucose DMEM/F12 1∶1 containing 10％ fetal bovine serum and 0.5％ mixture of penicillin and streptomycin.The morphology and growth of cells were observed with inverted phase contrast microscope.The positive cells of αsmooth muscle actin (α-SMA),desmin,neuron-glial antigen 2 (NG2),cluster of differentiation 31 (CD31) were counted by immunofluorescence.The percentage of positive cells was calculated.Results The microscopic examination showed cells of shuttle shape or star shape,mononuclear cells,binuclear cells occasionally,oval nucleus,rich cell plasma,growth in the shape of vortex or fence,and no contact inhibition.The percentage of positive cells ofα-SMA,desmin,NG2,and CD31 was (99.0± 1.2)％,(96.0±2.1)％,(99.0±0.7)％ and0,respectively.Conclusion The culture method for rat pulmonary capillary pericytes is successfully established.
