What is the Origin of Cellular Regenerative Signaling?

The concept is rooted in developmental biology and molecular endocrinology, specifically the study of growth factors, cytokines, and hormone receptor interactions. The term "regenerative signaling" emphasizes the proactive, restorative nature of these communications, moving beyond simple repair to active systemic rejuvenation. Clinical applications now focus on leveraging these endogenous pathways for therapeutic benefit.

What is the Mechanism of Cellular Regenerative Signaling?

Key components of this mechanism include the activation of pathways like mTOR for protein synthesis, AMPK for energy sensing, and sirtuins for DNA repair and metabolic regulation. Hormones such as growth hormone and IGF-1 play a direct role by binding to cell surface receptors, initiating intracellular cascades that stimulate cell proliferation, differentiation, and matrix production. Effective signaling ensures the efficient replacement of senescent cells and the structural integrity of tissues throughout the body.
