Notably, the amount of cell-surface CD274 was similar between donor and IPF cells, shown by the similar mean fluorescence intensity (MFI) of the Q3 population between the donor and IPF (Figure 2C, average Log (MFI) donor vs. IPF = 3.81 ± 0.08 vs. 3.92 ± 0.18, p = 0.18). This evidence concerns the gene CD274 and idiopathic pulmonary fibrosis.
