WebMay 5, 2024 · Abstract. Myocardial infarction (MI) can lead to irreversible loss of cardiomyocytes (CMs), primarily localized to the left ventricle (LV) of the heart. The CMs of the LV are predominantly derived from first heart field (FHF) progenitors, whereas the majority of CMs within the right ventricle originate from the second heart field (SHF) … WebJul 10, 2024 · Recent discoveries of at least two heart fields and dynamic nature of cardiac development as well as controversies regarding the participation of heart fields in development of different heart structures led us to investigate the dynamics of incorporation of the first and second heart fields and prospective fate of the straight heart tube by …
WebJun 1, 2014 · In mice, Nkx2.5 is expressed in the early first heart field, second heart field pharyngeal mesoderm, as well as pharyngeal endodermal cells underlying the second heart field. Currently, the specific requirements for Nkx2.5 in the endoderm versus mesoderm with regard to early heart formation are incompletely understood. WebApr 9, 2024 · Abstract The vertebrate heart integrates cells from the early-differentiating first heart field (FHF) and the later-differentiating second heart field (SHF), both emerging from the lateral plate mesoderm. In mammals, this process forms the basis for the development of the left and right ventricle chambers and subsequent chamber septation.
WebOct 14, 2014 · Deficiency of Rac1 in the second heart field impairs elongation and cytoskeleton organization of cardiomyocytes and results in congenital septal defects, thin right ventricle myocardium, and a bifid cardiac apex. Our study suggests that Rac1 signaling is critical to cardiomyocyte polarity and embryonic heart development. Introduction WebAug 1, 2024 · Descendants of the first heart field (FHF) cells are found in the left ventricle and a portion of left and right atrium, while descendants of the second heart field (SHF) …
