Fig. 4From: Knockout of integrin β1 in induced pluripotent stem cells accelerates skin-wound healing by promoting cell migration in extracellular matrixEffects of Itgb1-knockout on the function and survival of iPSCs cultured on Matrigel. a Representative fluorescence imaging (left) and quantification (right) of PKH26-labeled iPSCs adhered to plates with agarose, collagen and Matrigel (n = 5). b Representative fluorescence imaging (left) and quantification (right) of PKH26-labeled iPSC migration across the chamber membrane in the presence of agarose, collagen and Matrigel (n = 3). c Levels of iPSCs early apoptosis in the presence of agarose, collagen and Matrigel were determined by Annexin V/FITC staining (n = 3). d iPSC proliferation in the presence of agarose, collagen and Matrigel determined by CCK-8 assay (n = 6). p < 0.05, **p < 0.01, ***p < 0.001.
