The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field. The process whose specific outcome is the progression of the embryonic heart tube over time, from its formation to the mature structure. The heart tube forms as the heart rudiment from the heart field. The establishment, maintenance and elaboration of cell differentiation that results in the anterior/posterior subdivision of the embryonic heart tube. In Drosophila this results in subdivision of the dorsal vessel into to the posterior heart proper and the anterior aorta. The commitment of dorsal vessel cardioblast cells to a heart proper cell fate and their capacity to differentiate into heart cells. An example of this process is found in Drosophila melanogaster. The process whereby a relatively unspecialized cell acquires the specialized structural and/or functional features of a cell that will form part of the cardiac organ of an individual. The regionalization process by which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism. The commitment of cells to specific cardiac cell fates and their capacity to differentiate into cardiac cells. Cardiac cells are cells that comprise the organ which pumps blood through the circulatory system.
