Novel Video Imaging To Examine Cardiac Function In Xenopus Embryos, Judith Sull
Novel Video Imaging To Examine Cardiac Function In Xenopus Embryos, Judith Sull
Electronic Thesis and Dissertation Repository
Congenital heart defects (CHDs) occur in approximately 1% of live births and the etiology has been associated with disturbances in cardiogenesis. However, the majority of research examining CHDs relies on static morphological data, which does not elucidate how defects alter cardiac function. I used Xenopus laevis embryos to examine the association between CHDs and functional alterations using a novel imaging system that can obtain high- resolution images through a non-invasive procedure. A high-speed video camera and software were used to assess cardiac function, permitting functional characterization of late Xenopus cardiogenesis. Verification of the imaging system’s ability to detect changes in …
