摘要

The surfactant protein A (SP-A) gene was disrupted by homologous recombination in embryonic stem cells that were used to generate homozygous SP-A-deficient mice. SP-A mRNA and protein were not detectable in the lungs of SP-A(-/-) mice, and perinatal survival of SP-A(-/-) mice was not altered compared with wild-type mice. Lung morphology, surfactant proteins B-D, lung tissue, alveolar phospholipid pool sizes and composition, and lung compliance in SP-A(-/-) mice were unaltered.
