The orderly movement of an endocardial progenitor cell toward the midline to form the heart field. Cardiac muscle progenitor cells are non-terminally differentiated, mesoderm-derived cells that are committed to differentiate into endocardial cells of the heart.

The orderly movement of a myocardial progenitor cell toward the midline to form the heart field. Cardiac muscle progenitor cells are non-terminally differentiated, mesoderm-derived cells that are committed to differentiate into myocardial cells of the heart.

OBSOLETE. An interaction with a second organism mediated by a substance secreted by the first organism by a type III secretion system, where the two organisms are in a symbiotic interaction.

OBSOLETE. The process in which an organism effects a change in the structure or function of a second organism, mediated by a substance secreted by one of the organisms, where the two organisms are in a symbiotic interaction.

OBSOLETE. An interaction with a second organism mediated by a substance secreted by the first organism by a type II secretion system, where the two organisms are in a symbiotic interaction.

OBSOLETE. The directed movement of a motile cell or organism on, within or near a second organism towards a higher level of a physical stimulus involved in energy generation, such as light, oxygen, and oxidizable substrates, where the two organisms are in a symbiotic interaction.

OBSOLETE. The movement of a motile cell or organism in response to environmental oxygen on, within or near a second organism, where the two organisms are in a symbiotic interaction.

The orderly movement of a cardioblast toward the head and laterally to form the heart field. 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.

OBSOLETE. The directed movement of a motile cell or organism on, within or near a second organism towards a lower level of a physical stimulus involved in energy generation, such as light, oxygen, and oxidizable substrates, where the two organisms are in a symbiotic interaction.

OBSOLETE. Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter that contributes to the differentiation of an endocardial precursor cell.

OBSOLETE. The chemical reactions and pathways performed by an organism in a second organism, where the two organisms are in a symbiotic interaction.

OBSOLETE. Any process that increases the frequency, rate or extent of transcription from an RNA polymerase II promoter that contributes to the differentiation of a myocardial precursor cell.

OBSOLETE. An interaction with a symbiont organism mediated by a substance secreted by a host organism. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.

OBSOLETE. Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter that contributes to the differentiation of a myocardial precursor cell.

OBSOLETE. The directed movement of a motile cell or organism in response to a specific chemical concentration gradient on, within or near a second organism, where the two organisms are in a symbiotic interaction.

The process in which a relatively unspecialized mesodermal cell acquires the specialized structural and/or functional features of an endocardial precursor cell. A endocardial precursor cell is a cell that has been committed to a endocardial cell fate, but will undergo further cell divisions rather than terminally differentiate.

OBSOLETE. The directed movement of a motile cell or organism in the environment of a second organism in response to physical parameters involved in energy generation, such as light, oxygen, and oxidizable substrates, where the two organisms are in a symbiotic interaction.

The orderly movement of a neural crest cell from one site to another that will contribute to the morphogenesis of the outflow tract.

Any process that decreases the rate, frequency or extent of cell proliferation that contributes to the shaping of a heart valve.

Any process that modulates the rate, frequency or extent of cell proliferation that contributes to the shaping of a heart valve.
