Fig. 3. Representative DESI-MS ion images of normal kidney, RO, and RCC tissues. To better visualize the differences among the three tissue types for the six ions selected, the scale bars used are in unit of absolute intensity and were amplified by a factor of 4 (0–500 absolute intensity) for m/z 391.260, m/z 656.574, and m/z 835.530 of all the samples. (Reproduced with permission from Zhang et al.,45) Cancer Research PMC.) Cer, ceramide; CL, cardiolipin; DESI, desorption electrospray ionization; H&E, hematoxylin and eosin; MG, monoradylglycerolipids; MS, mass spectrometric; PI, glycerophosphoinositol; PS, glycerophosphoserine; RCC, renal cell carcinoma; RO, renal oncocytoma.
