Early Embryo Circulation

  • Branko Furst
Chapter

Abstract

Over the past several decades, the search for the unifying paradigm between the form and function of the early vertebrate embryo heart has focused on genetic patterns as the blueprints for early heart formation, enhanced by phylogenetic and morphologic observations. More recently, however, there has been a resurgence of interest in epigenetic factors such as intracardiac flow patterns and fluid forces as significant factors in early embryo cardiogenesis and vascular formation. The availability of new techniques such as confocal microscopy, phase contrast magnetic resonant imaging, digital particle velocimetry, and high-frequency ultrasonographic imaging, used for in vivo observation of embryonic flow dynamics, have provided new insights into the early embryo hemodynamics. The existing evidence no longer supports the accepted mode of heart’s peristaltic blood propulsion and has called for a radical re-evaluation of the traditionally accepted model of circulation.
