Forward genetics: identifying novel genes important for cardiovascular development
The ENU-induced mutant, refuse-to-fuse (ref) was found in a forward genetic screen for cardiac defects. ref was found to be a mutation in pdgfra leading to the identification of PDGF signaling as being important for cardiac fusion. For more information see Bloomekatz et al. 2017.
Quantitative live-imaging
Quantitative tracking of cardiomyocyte movement (Purple-to-Red) in wildtype and ref mutant embryos allows for the dissection of different properties of movement



External fertilization, optical transparency, large clutch size, ease of genetic manipulation, great genetic tractability and great scientific community are just some of the advantages that make zebrafish a great vertebrate model system with which to study cardiovascular biology
