Abstract: 1and has been initially targeted for the analysis of peptides and proteins present on or near the surface of tissue sections 2 . Imaging MS brings a new tool to bear on the problem of unraveling and understanding the molecular complexities of cells. It joins techniques such as immunochemistry and fluorescence microscopy for the study of the spatial arrangement of molecules within biological tissues. Many previous experiments using MS to image samples have focused on the measurement of the distribution of elements and small molecules in biological specimens, including tissue slices and individual cells 3‐5 . An extensive review on imaging by MS can be found in the article by Pacholski and Winograd 6

Mass Spectrometry Sampling Under Ambient Conditions with Desorption Electrospray Ionization
TL;DR: The DESI phenomenon was observed both in the case of conductive and insulator surfaces and for compounds ranging from nonpolar small molecules such as lycopene, the alkaloid coniceine, and small drugs, through polar compounds such as peptides and proteins.

Proteomic applications for the early detection of cancer.
TL;DR: Proteomic analyses of early-stage cancers have provided new insights into the changes that occur in the early phases of tumorigenesis and represent a new resource of candidate biomarkers for early stage disease as discussed by the authors.
MALDI imaging mass spectrometry: molecular snapshots of biochemical systems.
TL;DR: The current state of the art of MALDI-IMS is discussed along with some recent applications and technological developments that illustrate not only its current capabilities but also the future potential of the technique to provide a better understanding of the underlying molecular mechanisms of biological processes.

TL;DR: If SLN micrometastasis is used to determine the need for further lymphadenectomy, more sensitive intraoperative methods will be needed to avoid a second operation.

TL;DR: Intraoperative FS has low sensitivity in identifying MM within the SLN, and a combination of permanent H&E sections with deeper levels and S-100 and HMB45 IH dramatically increases the overall diagnostic sensitivity of SLN biopsy.

TL;DR: In situ hybridization studies showed that the transcript encoding the precursor is present in VD1, but not in RPD2, thus corroborating the single-cell MS analysis, and the small cardioactive peptides were shown to enhance the contractions of the auricle in vitro.
