Abstract:
Objective To observe the structure feature of cultured mesothelial cells, determine its anticoagulant and fibrinolytic activity, and provide a basis for selection of artificial vascular prostheses coating cells. Methods The greater omenta, aortae and subcutanenous connective tissue of SD rats have been taken for mesothelial cell, endothelial cell and fibroblast culture. The cultured mesothelial cells have been observed by light microscopy and electron microscopy. The 6 keto PGF 1? (the metabolite of prostacyclin)concentrations in medium were measured by rodioimmunoassay, Tissue plasminogen activator(t PA) activity was detected by chromogenic assay. Results The cultured mesothelial cells have many structure feature similar to endothelial cells. The average concentration of the 6 keto PGF 1? in mesothelial cell culture was higher than that in endothelial cells and fibroblasts culture, the t PA activity in mesothelial cells culture was also higher than that in fibroblasts, but there wasn't a significant difference between mesothelial cells and endothelial cells.Conclusion Mesothelial cells have similar structure and functions comparing with endothelial cells. It may be an ideal coating lining for artificial vascular impants. [
