(Submitter supplied) Cardiac trabeculation is a highly regulated process that starts with the delamination of cardiomyocytes from the compact wall to form stereotypical muscular ridges in the developing ventricle.  The Hippo signaling pathway has been implicated in cardiac development but many questions remain.  We investigated the role of Wwtr1, a nuclear effector of the Hippo pathway, in zebrafish and find that its loss results in hearts with reduced trabeculation. more...

(Submitter supplied) While the heart regenerates poorly in mammals, efficient heart regeneration occurs in certain amphibian and fish species. Zebrafish has been used extensively to study heart regeneration, resulting in a model in which preexisting cardiomyocytes dedifferentiate and reinitiate proliferation to replace the lost myocardium. However, there is limited knowledge about the cellular processes that occur in this rare population of proliferating cardiomyocytes during heart regeneration. more...

(Submitter supplied) Complex interplay between cardiac tissues is crucial for their integrity. The flow responsive transcription factor KLF2, which is expressed in the endocardium, is vital for cardiovascular development but its exact role remains to be defined. To this end, we mutated both klf2 paralogues in zebrafish, and while single mutants exhibit no obvious phenotypes, double mutants display a novel phenotype of cardiomyocyte extrusion towards the abluminal side. more...

(Submitter supplied) In contrast to mammals, zebrafish regenerate heart injuries via proliferation of cardiomyocytes located at the wound border. Here, we show that tomo-seq can be used to identify whole-genome transcriptional profiles of the injury zone, the border zone and the healthy myocardium. Interestingly, the border zone is characterized by the re-expression of embryonic cardiac genes that are also activated after myocardial infarction in mouse and human, including targets of Bone Morphogenetic Protein (BMP) signaling. more...

(Submitter supplied) Contrary to adult mammals, zebrafish are able to regenerate their heart after cardiac injury. This regenerative response relies, in part, on the endogenous ability of cardiomyocytes (CMs) to dedifferentiate and proliferate to replenish the lost muscle. However, CM heterogeneity and population dynamics during development and regeneration remain poorly understood. Through comparative transcriptomic analyses of the developing and adult zebrafish heart, we identified tnnc2 and tnni4b.3 expression as markers for CMs at early and late developmental stages, respectively. more...

(Submitter supplied) Heart formation requires the fusion of bilateral cardiomyocyte populations as they move toward the embryonic midline. The bHLH transcription factor Hand2 is essential for cardiac fusion; however, the effector genes that execute this function of Hand2 are unknown. Here, we provide the first evidence for a downstream component of the Hand2 pathway that mediates cardiac morphogenesis. Although hand2 is expressed in cardiomyocytes, mosaic analysis demonstrates that hand2 plays a non-autonomous role in regulating cardiomyocyte movement. more...

(Submitter supplied) The zebrafish heart remarkably regenerates after a severe ventricular damage followed by inflammation, fibrotic tissue deposition and removal concomitant with cardiac muscle replacement. We have investigated the role of the endocardium in this regeneration process. 3D-whole mount imaging in injured hearts revealed that GFP-labelled endocardial cells in ET33mi-60A transgenic fish become rapidly activated and highly proliferative at 3 days post cryoinjury (dpci). more...

In late epiboly, drl:EGFP is detectable as a band of scattered EGFP-fluorescent cells; after gastrulation, drl:EGFP-positive cells coalesce at the embryo margin that then in somitogenesis break down into the anterior and posterior lateral plate with subsequent cell migrations that form the posterior vascular/hematopoietic stripes and the anterior cardiovascular and myeloid precursors. more...
