H&E and immunohistochemical staining images of patient-derived lung cancer tumor tissues and lung cancer PDOs. Results of IHC analysis using cancer tissues (A) and organoids (B) derived from the same patient with lung cancer; in lung cancer organoids, the expression patterns of lung cancer characteristic markers (TTF-1, P63, CK7 and Napsin A) were well maintained, the same as in patient lung cancer tissues
