FIG. 3.

Immunohistochemical locatization of proliferating lung mesenchymal stromal cells (LMSCs) (Sca1-positive, CD45/CD31/EPCAM-negative, BrdU-positive cells) 3 days after pneumonectomy in 3 month mice. (A)–CD45 (green), DAPI (blue); (B)–CD31 (green), DAPI (blue); (C)–EPCAM (green), DAPI (blue); (D)–Sca1 (green), DAPI (blue); (E)–BrdU (green), DAPI (blue); (F), (G)–CD45/CD31/EPCAM (green), Sca1 (blue), BrdU (red). The combined staining illustrates the topographic location of proliferating LMSCs within the lung alveolar parenchyma during postpneumonectomy regeneration.
