Caption : raman spectra of calvarial bone and tibia of ddy mice at 2 and 4 wks old (a). the intensities of υ1 phosphate/amide iii of calvaial bone and tibia from 4 wks old mice were visualized (b) and quantified (c). a p-value of less than 0.05 was considered significant (*).

File Name : supplemental fig.2.tiff

Caption : a representative load function of the dynamic indentation tests. the lower panel indicates the superimposed oscillations and sinusoidal indentations within the dynamic indentation tests.

File Name : supplemental fig.3.tiff

Caption : a diagram for the delayed stress-strain response in viscoelastic materials to calculate the tangent of the phase lag (tan δ).

File Name : supplemental fig.4.tiff

Caption : the linear approximation fits prior to the onset of unloading obtained from load-controlled (a) and displacement-controlled (b) indentations.
