Figure 1From: Deficient repair response of IPF fibroblasts in a co-culture model of epithelial injury and repairSchematic diagram depicting epithelial-primary fibroblast co-culture scratch wound model. (A) A549 and fibroblasts are attached on either side of trans-well insert coated with collagen. (B) Scratch wound is created by running a sterile pipette tip across. (C) Resultant denuded area. (D) Fibroblast transmigration across trans-well into denuded area.Back to article page
