Figure 5
AFM nanoindentation data measured for endothelia from db/db and db/+ mice aortas. Upper row: Data for an 11-week-old control db/+ mouse. Middle row: Data for a 19-week-old control db/+ mouse. Bottom row: Data for an 11-week-old diabetic db/db mouse. (A,D,G) Values of the apparent elastic modulus derived from fragments of indentation curves near the contact point ECP. (B,E,H) Values of the apparent elastic modulus derived from fragments of indentation curves near the maximum load E ML . (C,F,I) Values of the L parameter. A logarithmic (base 10) scale is used for the colour scale. In all images, large spatial and mechanical sample heterogeneity can be observed.
