Effect of heparinase III digestion on the spatial distribution of PCM elastic properties. Evaluation was performed at radial increments of 0.5 μm from the PCM inner edge. (A) Outward stiffness progression of PCM elastic moduli from the PCM inner edge for control (black) and digested (white) samples. Regions within 1.0 μm from the PCM inner edge exhibited higher elastic moduli with heparinase III digestion as compared to undigested controls (a: p < 0.05 for digested as compared undigested controls). (B) Outward progression of biochemical composition from the PCM inner edge for control (black) and digested (white) samples. Within each radial increment, data represent the relative composition based on the percent of total IF labeled PCM area occupied by each antibody/antibody combination. Data presented as Mean ± SEM (n = 25).
