Cellular Renewal Pathways

Meaning

Cellular Renewal Pathways are the specific, interconnected molecular signaling cascades and regulatory processes that govern the lifecycle of a cell, including proliferation, differentiation, repair, and programmed death (apoptosis or autophagy). These pathways are tightly regulated by hormones and metabolic cues to ensure that the replacement of old cells with new ones is balanced and efficient throughout the body. Dysfunction in these pathways is a hallmark of biological aging and chronic disease.
