Abstract:
BACKGROUND:Primary culture of glomerular mesangial cells was less achievement ratio,short survival time,and less passage times.In particular,extraction of renal glomerulus remains difficult for culturing highly pure mesangial cell OBJECTIVE:To establish a more simple.high successful rate and good reproducibility method of human mesangial cells in primary cultureMETHODS:Kidneys jsolated from induction of labor with water bag voluntary were cut into pieces.and human mesangial cells were cultured with eugenic selection methods.Morphology was observed using inverted phase contrast microscope and transmission electron microscope,cell phenotype was detected using immunohistochemical method,and vimentin expression was observed using laser scanning confocal microscope.RESULTS AND CONCLUSION:The cultured mesangial cells were fusiform-shaped,irregular star-shaped,and slender.Organelle was rich in cytoplasm,cell process was clear,and microvillus was observed on the cell membrane.The cells expressed a-actin,myosin,vimentin,desmin but not expressed cytokeratin and Ⅷ factor.Laser scanning confocal microscope demonstrated that vimentin expression was positive and had the characteristics of fiber bundles.This suggested that the cultured intercapillary cells were coincidence with the characteristics of mesangial cell The renal corticaI tissue combined eugenic selection method was a simple and efficient method to culture human mesangial cells.
