- W2012199851 abstract "A series of experiments was performed to compare the ability of adult human endothelial and mesothelial cells to attach and spread upon ePTFE graft material. Both cell types were harvested enzymatically and grown in culture. Two types of adhesion assay were used to assess the ability of the cultured cells to attach to ePTFE either uncoated or precoated with a variety of substrate proteins. The results showed that fibronectin, laminin, type 4 collagen and preclotted blood all greatly improve the attachment rate of endothelium to ePTFE. The extracellular matrix proteins, however, give patchy cell attachment, whereas cells seeded onto preclotted ePTFE form a virtually confluent monolayer after one hour's incubation. The matrix proteins similarly improve mesothelial attachment, although in all cases attached cells remain largely rounded up, with relatively few spreading on the surface. Mesothelial attachment to preclotted ePTFE is no better than attachment to the untreated material. It would seem that a preclotted graft seeded with endothelial cells is the combination most likely to result in a confluent monolayer within one hour.
