Gene expression profiling of MLP29 hepatic progenitor cells after α 5 β 1 integrin blockade and HGF/SF stimulation. (A) (B) Plots showing the changes in the expression of gene sets involved in cell adhesion and migration, respectively. Data from three independent experiments were pooled and subjected to permutation analyses to assess the expression level changes of gene sets obtained from the Molecular Signatures Database. The resulting data are presented as color-encoded plots in which a p-value close to 1 indicates significant up-regulation, and a p-value close to 0 indicates a significant down-regulation.
