In the mammalian lung, an apparently homogenous mesh of capillary vessels surrounds each alveolus, forming the vast respiratory surface across which oxygen transfers to blood. Here, we use single cell analysis to elucidate the cell types, development, renewal, and evolution of the alveolar capillary endothelium. We show that alveolar capillaries are mosaics; like the epithelium lining the alveolus, the alveolar endothelium is made up of two intermingled cell types, with complex ‘swiss cheese’-like morphologies and distinct functions. One cell type we term the ‘aerocyte’ is specialized for gas exchange and leukocyte trafficking, and unique to the lung. The other, termed gCap (general capillary) is specialized to regulate vasomotor tone and functions as a stem/progenitor cell in capillary homeostasis and repair. The two cell types develop from bipotent progenitors, they mature gradually, and are affected differently in disease and aging. This cell type specialization is conserved between mouse and human but is not found in alligator or turtle lungs, suggesting that specialized capillary cells arose during evolution of the mammalian lung. The discovery of capillary cell type specialization transforms our understanding of the structure, function, regulation, and maintenance of the air-blood barrier and gas exchange in health, disease, and evolution.
