Paracrine signaling via secretome-mediated immunomodulation and tissue regeneration (None established; commonly referred to as "paracrine signaling" or "secretome-mediated effects")

Paracrine signaling via secretome-mediated immunomodulation and tissue regeneration refers to the collective action by which cells secrete bioactive molecules—including cytokines, growth factors, and extracellular vesicles—into their local environment to influence neighboring cells' behavior without direct contact. These secreted elements can modulate immune responses by shifting tissues from pro-inflammatory states toward healing/regeneration after injury. The “secretome” encompasses all soluble proteins/factors released by cells—including those packaged within extracellular vesicles—which can deliver their cargo directly into recipient cells through membrane fusion or surface interactions with cell receptors. This mode of intercellular communication plays critical roles across development, homeostasis maintenance, inflammation resolution/regeneration after damage—and also contributes pathologically to cancer progression/metastasis when dysregulated [1][2][4][5]. While highly promising therapeutically—especially using stem cell-derived EVs—the approach faces challenges related to specificity/safety due to its broad systemic effects [7].
