Increased NK cell adhesion to Ch films with adsorbed Fg. NK cells were incubated for 1 h in Ch films without (Ch) and with adsorbed Fg (Ch/Fg), washed, fixed and stained. Cells were imaged in an inverted microscope and counted. (a) Representative images of cells adherent to films. Scale bar, 40 µm. (b) Summary of data obtained in five independent experiments. Each symbol represents the average number of cells in one experiment with three replicas. Bars show the average of the different experiments. Data are statistically significant (*p < 0.05; Wilcoxon test).
