Detailed explanation-1: -In paracrine signaling, a molecule released by one cell acts on neighboring target cells. An example is provided by the action of neurotransmitters in carrying signals between nerve cells at a synapse.
Detailed explanation-2: -Paracrine signaling allows cells to locally coordinate activities with their neighbors. Although they’re used in many different tissues and contexts, paracrine signals are especially important during development, when they allow one group of cells to tell a neighboring group of cells what cellular identity to take on.
Detailed explanation-3: -Paracrine signaling between the mesenchymal and epithelial cells and interactions with the extracellular matrix (ECM) are the major components of the stem cell niche that modulates cell behavior [1, 9].
