Cell potencyCell potency is a cell's ability to differentiate into other cell types. The more cell types a cell can differentiate into, the greater its potency. Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally unipotency. Totipotency (Lat. totipotentia, "ability for all [things]") is the ability of a single cell to divide and produce all of the differentiated cells in an organism.
Cell migrationCell migration is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations. Cells often migrate in response to specific external signals, including chemical signals and mechanical signals. Errors during this process have serious consequences, including intellectual disability, vascular disease, tumor formation and metastasis.
Facteur natriurétique auriculaireLe facteur natriurétique auriculaire (FNA) ou facteur atrial natriurétique (FAN) (en anglais, Atrial Natriuretic Factor ou ANF), encore appelé peptide natriurétique atrial (ou ANP de l'Atrial Natriuretic Peptide ), auriculine, atriopeptine ou cardionatrine, est une hormone polypeptidique essentiellement synthétisée par l'atrium droit du cœur. Il participe à l'homéostasie du sodium, du potassium et de l'eau en agissant sur l'excrétion rénale, et possède une action vasodilatatrice.
