Identifying cell-specific\n                  <jats:italic>N<\/jats:italic>\n                  -glycan structures in human lungs is critical for understanding the chemistry and mechanisms that guide cell-cell and cell-matrix interactions and determining nuanced functions of specific\n                  <jats:italic>N<\/jats:italic>\n                  -glycosylation. Our study, which used matrix-assisted laser desorption\/ionization (MALDI) mass spectrometry imaging (MSI) combined with co-detection by indexing (CODEX) to reveal the cellular origin of\n                  <jats:italic>N<\/jats:italic>\n                  -glycans, is a significant step in this direction.
