Key result
MALDI-Imaging Mass Spectrometry successfully mapped the spatial distribution of proteins, including collagen VI α-3 and NDRG2, in stenotic aortic valve tissue, revealing distinct molecular regions that complement conventional histology.

Offers complementary molecular mapping in animal aortic stenosis models; leaves open human translation and clinical utility.
Mouriño-Álvarez et al. (2016) conducted an observational in Calcific aortic stenosis (n=6). MALDI-Imaging Mass Spectrometry vs. Conventional histology was evaluated on Spatial distribution of proteins and peptides in aortic valve tissue. MALDI-Imaging Mass Spectrometry successfully mapped the spatial distribution of proteins, including collagen VI α-3 and NDRG2, in stenotic aortic valve tissue, revealing distinct molecular regions that complement conventional histology.
