GlossaryParacrine Signaling (paracrine interaction)

cells communicate by releasing molecules to nearby cells

Paracrine signaling is a form of cell-to-cell communication where a cell produces signaling molecules, such as growth factors or cytokines, that affect nearby target cells within the same tissue. Unlike endocrine signaling, which involves hormones traveling through the bloodstream to distant targets, paracrine signals act locally, ensuring a rapid and specific response in the immediate cellular environment. This type of signaling is crucial in processes like wound healing, immune responses, and hair follicle regulation.
