Detailed knowledge of tissue-specific metabolic profiles of the lung is vital for elucidating the molecular pathological signature of lung aging and exploring potential metabolic targets to improve aging lung function. In this study, a spatially resolved metabolomics approach based on airflow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI–MSI) was proposed to investigate tissue-specific metabolic disturbances in the lungs of naturally aging mice. This dataset was uploaded at MetaboLights (accession MTBLS8771), but it is not yet curated. This figshare dataset contains the files in MTBLS8771, which are temporarily available or peer-review.
