Increased Hemodynamic Load in Early Embryonic Stages Alters Endocardial to Mesenchymal Transition

ABSTRACT: Normal blood flow is essential for proper heart formation during embryonic development, as abnormal hemodynamic load (blood pressure and shear stress) results in cardiac defects seen in congenital heart disease. However, the progressive detrimental remodeling processes that relate altered blood flow to cardiac defects remain unclear. Outflow tract banding was used to increase hemodynamic load in the chicken embryo heart between Hamburger and Hamilton stages 18 and 24. Increased hemodynamic load induced increased cell density in outflow tract cushions, fewer cells along the endocardial lining, endocardium junction disruption, and altered periostin expression as measured by confocal microscopy analysis. Proteomic mass-spectrometry analysis quantified altered protein composition after banding.

Normal blood flow is essential for proper heart formation during embryonic development, as abnormal hemodynamic load (blood pressure and shear stress) results in cardiac defects seen in congenital heart disease (CHD). However, the detrimental remodeling processes that relate altered blood flow to cardiac malformation and defects remain unclear. Heart development is a finely orchestrated process with rapid transformations that occur at the tissue, cell, and subcellular levels. Myocardial cells pl ...[more]

Project description:Ischemic cardiopathy is the leading cause of death in the world, for which efficient regenerative therapy is not currently available. In mammals, after a myocardial infarction episode, the damaged myocardium is replaced by scar tissue featuring collagen deposition and tissue remodelling with negligible cardiomyocyte proliferation. Zebrafish, in contrast, display an extensive regenerative capacity as they are able to restore completely lost cardiac tissue after partial ventricular amputation. Due to the lack of genetic lineage tracing evidence, it is not yet clear if new cardiomyocytes arise from existing contractile cells or from an uncharacterised set of progenitors cells. Nonetheless, several genes and molecules have been shown to participate in this process, some of them being cardiomyocyte mitogens in vitro. Though questions as what are the early signals that drive the regenerative response and what is the relative role of each cardiac cell in this process still need to be answered, the zebrafish is emerging as a very valuable tool to understand heart regeneration and devise strategies that may be of potential value to treat human cardiac disease. Here, we performed a genome-wide transcriptome profile analysis focusing on the early time points of zebrafish heart regeneration and compared our results with those of previously published data. Our analyses confirmed the differential expression of several transcripts, and identified additional genes the expression of which is differentially regulated during zebrafish heart regeneration. We validated the microarray data by conventional and/or quantitative RT-PCR. For a subset of these genes, their expression pattern was analyzed by in situ hybridization and shown to be upregulated in the regenerating area of the heart. The specific role of these new transcripts during zebrafish heart regeneration was further investigated ex vivo using primary cultures of zebrafish cardiomyocytes and/or epicardial cells. Our results offer new insights into the biology of heart regeneration in the zebrafish and, together with future experiments in mammals, may be of potential interest for clinical applications. In order to study zebrafish heart regeneration, a time course experiment was realized where amputated heart regenerating were compared to control heart. Samples in triplicate were extracted at 1, 3, 5 and 7 days post-amputation.

Project description:Retinoic acid (RA), the bioactive derivative of vitamin A, is essential for vertebrate heart development. Both excess and reduced RA signaling lead to cardiovascular malformations, particularly affecting the cardiac outflow tract (OFT). The cellular mechanisms underlying the effects of RA signaling during OFT morphogenesis are not fully understood. To address this question, we used transient maternal RA supplementation to rescue the early lethality resulting from inactivation of the murine retinaldehyde dehydrogenase 2 (Raldh2) gene. By embryonic day 13.5, Raldh2-/- hearts exhibited OFT septation defects. Although cardiac neural crest cells (cNCC) were present in OFT cushions of Raldh2-/- mutant embryos, we observed that cNCC were ectopically located in the peripheral region of the endocardial cushions, closer to the myocardium rather than immediately subjacent to the endocardium. Mislocated cNCC were aligned in parallel instead of perpendicular arrays to the endocardial surface within the proximal OFT. Supernumerary mesenchyme was generated both in and ex vivo within the cushions by Raldh2-/- mutant endocardium and found in place of the cNCC in a subendocardial, medial position. Although mislocated and misoriented, mutant cNCC resembled wildtype cells in their compaction density and individually elongated shape. Our data show that RA signaling acts on cNCC orientation relative to the septation plane and position within OFT cushions during septation process. Transcriptomic analysis and pathway-specific readout suggest that up-regulation of the Bmp pathway may be responsible for increased endothelial-to-mesenchymal transition, leading thereby to displacement of cNCC. E10.5 stage embryonic mouse outflow tracts were microdissected. Four pools of four outflow tracts were established for wildtype (WT) and mutant (Raldh2-/-) embryos derived from dams whose food had been supplemented with all-trans-RA (Sigma) directly mixed into powdered food at 0.1 mg/g food and offered between E7.5 and E8.5. Total RNA was extracted using Macherey-Nagel NucleoSpinÂ® RNA columns without on-column DNase digestion.
