Protein signalling in heart development Protein signalling in heart development The heart is the first functional organ in a vertebrate embryo. There are 5 stages to heart development. Specification of cardiac precursor cells: The lateral plate mesoderm delaminates to form two layers: the dorsal somatic (parietal) mesoderm and the ventral splanchnic (visceral) mesoderm. The heart precursor cells come from the two regions of the splanchnic mesoderm called the cardiogenic mesoderm. These cells can differentiate into endocardium which lines the heart chamber and valves and the myocardium which forms the musculature of the ventricles and the atria. The heart cells are specified in anterior mesoderm by
Renovation of the Heart Renovation of the Heart Renovation of the Heart: Putting on the Character of Christ is a 2002 Christian book written by Dallas Willard. "Renovation of the Heart" proposes that the human self is made up of several interrelated components: one's spirit, i.e. one's "heart" or "will"; one's mind, or the collection of one's thoughts and feelings; the body; one's social context; and one's soul.
