MALDI-MS imaging and proteomic analysis of polypoid degeneration. (a) Ion maps from a peptide acquisition run showing the spatial distribution of six peptides with elevated relative intensity throughout the lesion. White arrows denote the lesion. The donor was a 74-year-old female. (b) Representative mass spectrum acquired from the lesion region. The annotated peaks correspond to the ion maps in panel (a). MALDI-MS, matrix-assisted laser desorption/ionisation-mass spectrometry; m/z, mass-to-charge ratio. Scale bars, 5 mm
