Effects of HAV and RGD gradients on transcription factor Sox9 expression. Maximum projection images and quantification across 10 regions of nuclear Sox9 fluorescence (aqua) for gradients of a, b RGD and c, d HAV peptides after 1 day. Representative maximum projection images of nuclei stained for Sox9 in e high or f low RGD regions and g high or h low HAV regions. Generally, higher nuclear Sox9 was observed with decreasing RGD and for increasing HAV. Error bars represent standard error around the mean (s.e.m.); n > 300 cells per zone, ***p < 0.001, *p < 0.05 compared to lowest peptide region (gray dashed line). Scale bars: a, c 1 mm, e–h 10 µm
