Chemical analysis of melanomastromal interactions. Regions of interest are extracted from tumors and from progressively increasing distance in stroma (R1–R7). Two duplicated samples from day 20, 24 and 28 are used. (A) The spectral region of 1200–1300 cm−1, corresponding to collagen specific peaks, is presented to show the magnitude of changes. (B) CDM is used to visualize the differences among spectra. Regions of transition are highlighted in squares, including the collagen region (red square).
