From: Three-Dimensional Mass Spectrometry Imaging Identifies Lipid Markers of Medulloblastoma Metastasis
The calculated mean spectra for (a) grey matter, (b) white matter, and (c) tumor regions mouse brain containing a non-metastasizing medulloblastoma primary tumor and the (d) grey matter, (e) white matter, and (f) tumor regions in a mouse brain containing a metastasizing medulloblastoma primary tumor as defined by k-means segmentation. The lipidome of the tumor is comparatively very different to the grey and white matter regions based on changes in the measured relative abundances of metabolites throughout the spectrum. Differences between metastasizing and non-metastasizing tumors are subtler.
