cardioblast cell fate specification
cardioblast cell fate specification
The process in which a cell becomes capable of differentiating autonomously into a cardioblast cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. A cardioblast is a cardiac precursor cell. It is a cell that has been committed to a cardiac fate, but will undergo more cell division rather than terminally differentiating.
