Summary Introduction
To discriminate: The method of signaling based on distance from a source to reception.
Introduction: The cell signaling is the process of cell communication within the body. It is the ability of cells that perceive and respond to the micro-environment in the basis of tissue repair, immunity, and development. It is classified into five types namely intracrine, autocrine, juxtacrine, paracrine, and endocrine.
