PAM inhibition effect in 3D lung cancer spheroids. Morphological change of 3D A549 spheroids (a) and 3D SK-MES-1 spheroids (b) after PAM treatment. Live/dead assay of 3D A549 spheroids (c) and 3D SK-MES-1 spheroids (d) with PAM treatment for 48 h; the qualification of dead cells by ImageJ software were presented in the right panel. Stemness-related mRNA expression of (e) 3D A549 spheroids and (f) 3D SK-MES-1 spheroids. Nontreated spheroids were used as control. Significance was presented as and in all experiments.
