sinoatrial node cell fate commitment

The commitment of cells to sinoatrial (SA) node cell fates and their capacity to differentiate into SA node cells. SA node cells are pacemaker cells that are found in the sinoatrial node.

sinoatrial node cell differentiation

The process in which a relatively unspecialized cell acquires specialized features of a sinoatrial (SA) node cell. SA node cells are pacemaker cells that are found in the sinoatrial node.

SA node cell to atrial cardiac muscle cell signaling

Any process that mediates the transfer of information from an SA node cardiomyocyte to an atrial cardiomyocyte.

sinoatrial node cell development

The process whose specific outcome is the progression of a sinoatrial (SA) node cell over time, from its formation to the mature state. SA node cells are pacemaker cells that are found in the sinoatrial node.

sinoatrial node development

The process whose specific outcome is the progression of the sinoatrial (SA) node over time, from its formation to the mature structure. The SA node is part of the cardiac conduction system that controls the timing of heart muscle contraction. It relays electrical signals to the AV node.

SA node cell-atrial cardiac muscle cell adhesion involved in cell communication

The attachment of SA node cardiomyocyte to an atrial cardiomyocyte via adhesion molecules that results in the cells being juxtaposed so that they can communicate.

nicotinate nucleotide salvage

The generation of nicotinate nucleotide without de novo synthesis.

SA node cell to atrial cardiac muscle cell communication

The process that mediates interactions between an SA node cardiomyocyte and its surroundings that contributes to the process of the SA node cardiomyocyte communicating with an atrial cardiomyocyte in cardiac conduction. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment.

SA node cell to atrial cardiac muscle cell communication by electrical coupling

The process that mediates signaling interactions between an SA node cardiomyocyte and an atrial cardiomyocyte by transfer of current between their adjacent cytoplasms via intercellular protein channels.

deoxyguanosine salvage

Any process that generates deoxyguanosine from derivatives of it, without de novo synthesis.
