Figure 2

Hydrogel mechanical characterization. Panel A shows three representative force versus vertical displacement curves measured on three different hydrogels (100% Alginate, 75%:25% Alginate:Matrigel, 50%:50% Alginate:Matrigel). The z = 0 corresponds to the vertical piezo displacement where the AFM tip gets into contact with the hydrogel surface. Panel B shows the Young modulus average and standard deviation, STD) for the different hydrogels probed by AFM nanoindentation: bar colours correspond to different alginate concentrations, while matrigel concentration is shown along the x axis (Kruskal-Wallis test, p < 0.05).
