To establish a reproducible model for culture of human peritoneal mesothelial cells (HPMCs), and observe the expressions of extracellular matrix (ECM) protein and interleukin-8 (IL-8) in HPMC.
Mesothelial cells were isolated from human omenta by trypsin EDTA disaggregation. HPMCs were identified by morphology and streptomyces protein-peroxidase (SP) method. In the same way, expressions of fibronectin, collagen type III, V and transforming growth factor beta 1 (TGF beta 1) were measured. Expression of IL-8 mRNA and FN mRNA in the HPMCs was detected by reverse transcription (RT) and polymerase chain reaction (PCR) amplification.
Confluent HPMCs appeared multipolar under microscope; numerous surface microvilli and an abundant endoplasmic reticulum were observed. Cultured HPMCs coexpressed cytokeratin and vimentin, and synthesized fibronectin, TGF beta 1 and collagen types III (instead of type V). Expressions of IL-8 mRNA and FN mRNA were also observed in HPMCs.
Establishment of cultured HPMCs model will provide the basis of the research in preventment of peritoneal fibrosis and roles of IL-8 in peritoneal dialysis.
