Abstract Mass spectrometry imaging has the potential to revolutionize omics by characterizing molecular changes with spatial context. In this study, we optimized spatial lipidomics protocols to analyze zebrafish embryos, an alternative to classical animal models in the environmental toxicology field. Specifically, a conventional MALDI-MSI technique and a recently developed technique called MALDI-2 were evaluated. The results show that both techniques allow reproducible tissue section analysis with high spatial resolution. By combining them with chemometric analysis, a clear differentiation has been observed in the lipid content of different regions of the embryo body, demonstrating the utility of these techniques in future (eco)toxicological studies.
