13 mar 2024 · These detailed findings into the cellular social interactions and specialization of cardiac cell types constructing and remodelling the human heart offer new insights into structural heart...
24 wrz 2020 · The heart is a complex organ, composed of four morphologically and functionally distinct chambers (Fig. 1a). Deoxygenated blood from the low-pressure right atrium and ventricle is propelled into...
Morchella can produce two types of spores in its life cycle: meiotic ascospores and mitotic mitospores. In general, the reproduction and transmission of fungi can be carried out via asexual (or mitospores) and/or sexual spores (or meiotic spores), which can be haploid, diploid or polyploid, with each one having their own characteristics in ...
EARLY HEART TUBE FORMATION AND ELONGATION: SWITCHING FROM PROLIFERATION TO DIFFERENTIATION. Cardiac morphogenesis involves a series of iterative steps of progenitor cell expansion, intercellular signaling, transcriptional response, patterning, and differentiation into more specialized cell types.
However, on the macro and micro (electron) level atria, ventricles, myocardium, conduction system, valves and the coronary system of the heart are for all practical purposes the same in all mammals. Overall similarities of cardiac morphology outweigh the differences among mammalian species. Functional Similarity of the Mammalian Heart
15 mar 2011 · In this study, we report patterns of proliferation and gene expression in tubular and chamber-forming stages of the human heart, supplementing our account with 3-dimensional (3D) analyses presented in interactive fashion. Our findings show the comparability of the mechanisms governing cardiac development in humans, mice, and chickens.
30 sty 2023 · In general, the reproduction and transmission of fungi can be carried out via asexual (or mitospores) and/or sexual spores (or meiotic spores), which can be haploid, diploid or polyploid, with each one having their own characteristics in terms of morphology, size and ornamentation color.
