Avian models of cardiovascular development have played a key role in elucidating the mechanisms by which congenital heart defects form during critical periods of early heart development. However, current avian models are restricted to narrow developmental windows, thereby limiting one's ability to study the manifestation of cardiac defects over a larger, more complete timescale. The work presented in this thesis uses novel techniques in an avian model coupled with multiscale imaging modalities to study how transient interventions during early heart formation affect the overall development of the heart. 000007535 542__ $$fIn copyright - single owner 000007535 650__ $$aPhenotype$$023948 000007535 650__ $$aAnimals$$014770 000007535 650__ $$aHeart$$019927 000007535 650__ $$aModels, Animal$$033025 000007535 650__ $$aHeart Defects, Congenital$$019936 000007535 650__ $$aMicroscopy, Electron$$022283 000007535 691__ $$aSchool of Medicine$$041369 000007535 692__ $$aDepartment of Biomedical Engineering$$041397 000007535 7001_ $$aRykiel, Graham$$uOregon Health and Science University$$041354$$10000-0003-0918-3926 000007535 7201_ $$aRugonyi, Sandra$$uOregon Health and Science University$$041354$$7Personal$$eAdvisor 000007535 8564_ $$9f0eb3ceb-9a84-4fe2-a94e-50f3c9cd77cb$$s4438367$$uhttps://digitalcollections.ohsu.edu/record/7535/files/rykiel.graham.2019.pdf$$ePublic$$2eea60f35ae0aec5929234452b7463759$$31 000007535 905__ $$a/rest/prod/2b/88/qc/73/2b88qc733 000007535 909CO $$ooai:digitalcollections.ohsu.edu:7535$$pstudent-work 000007535 980__ $$aTheses and Dissertations
