Cellular Command Signals

Meaning

Cellular command signals are the complex network of molecular and chemical messages—including hormones, cytokines, growth factors, and neurotransmitters—that precisely dictate a cell’s function, behavior, and ultimate fate. These signals govern essential biological processes such as proliferation, differentiation, energy metabolism, and programmed cell death (apoptosis). In the context of hormonal health, these signals represent the fundamental language through which the endocrine system communicates its systemic directives to target cells throughout the entire body.
