EPCAM and idiopathic pulmonary fibrosis: Notably, IPF-derived cells formed significantly larger organoids compared to the non-IPF group, for both unfractionated (non-IPF organoids mean size 78.45 ± 8.00 μm, IPF organoids mean size 92.70 ± 26.83 μm) and EpCAM+ (non-IPF organoids mean size 64.45 ± 1.47 μm, IPF organoids mean size 82.51 ± 14.42 μm) cultures (Figure 2B).
