Abstract
Alveolarization, the final stage of lung development, promotes gas-exchange by dividing the sac-like terminal airspaces of the lung into thin-walled pockets. Myofibroblasts are found at sites of septation, and mouse mutants in PDGFR alpha signaling lack myofibroblasts and air sacs fail to septate, suggesting that myofibroblasts play a role in septation. Further, a similar arrest in alveolarization is observed in diseases like bronchopulmonary dysplasia (BPD), a disease of premature infants that twin studies implicate may have important genetic contributions. In this thesis, I explore the developmental origins of myofibroblasts in mouse and the genetic basis of BPD. I first describe a novel protocol developed to extract DNA from dried blood spots taken from newborn infants that can be used in genotyping and genome-wide association studies (GWAS). I then describe an agnostic exploration of the genetic basis of BPD. Finally, I describe the use of genetic lineage tracing in mice to identify airway smooth muscle cells as a source of ductal myofibroblasts during lung development.
