PMCs in postnatal lung homeostasis. (A) PMCs were labeled by tamoxifen administration at Postnatal Day (P) 4. Lungs, analyzed at P13, showed selective labeling of PMCs. (B) P4-labeled lungs were analyzed at 30 weeks of life. The PMC label was retained in the mesothelium. Labeled cells were not found within the lung mesenchyme. Scale bar = 100 μm.
