Spatial transcriptomics reveals club cell features and strong CLDN18 expression along the mucinous pathway to invasive mucinous adenocarcinoma.
Invasive mucinous adenocarcinoma (IMA) of the lung is a distinct subtype of lung adenocarcinoma with unique clinicopathologic features; however, its histogenesis remains incompletely understood. Although mucinous metaplasia has been suspected as a precursor lesion, direct molecular evidence supporting this progression...
