NT5E and idiopathic pulmonary fibrosis: All ten cell lines were consistent with MSC expression of classical MSC markers: CD44, CD73, CD90, CD105 and HLA-ABC and showed lack expression of lineage markers: CD14, CD45 and HLA-DR as summarized in Fig. 1D. No difference in expression of cell surface markers was noticed between aMSC isolated from IPF patients and HCs.
