FTIR intensity images of the tendons created by peak integration mapping of the 1338 cm⁻¹, 1560 cm⁻¹, 1730 cm⁻¹, and 2932 cm⁻¹ absorbance bands. Tendons from the nCH rabbits have a uniform distribution of protein-specific and the collagen-specific signals. The intensity of the lipid-specific signals in these tendons is relatively low. In tendons from the hCH rabbits, the distribution of protein-specific and collagen-specific signals is not uniform. In these tendons, the areas of lipid-specific signals are evident (delineated with dotted lines). Of note is the observation that in the lipid-rich areas, the intensity of protein-specific and collagen-specific signals is relatively low. Intensity scales [A] are placed on the top. Bars = 200 μm
