What is the Origin of Tissue Repair Molecules?

This term originates from molecular biology, immunology, and endocrinology, synthesizing the various chemical agents involved in wound healing and regeneration. The concept has gained prominence in longevity science, which views the natural decline in the production and efficacy of these molecules as a key driver of age-related deterioration and delayed recovery from injury.

What is the Mechanism of Tissue Repair Molecules?

The action of these molecules begins with their release from platelets, immune cells, and local tissue cells at the site of damage, where they bind to specific cell surface receptors to initiate a cascade of events. Growth factors, such as fibroblast growth factor (FGF) and vascular endothelial growth factor (VEGF), stimulate cell division and angiogenesis, while certain cytokines regulate the influx of immune cells to clear debris. Anabolic hormones like growth hormone and IGF-1 further sustain the process by driving the synthesis of new extracellular matrix proteins and structural cells.

Tissue Repair Molecules

Meaning

Tissue repair molecules are a diverse class of endogenous signaling compounds, including growth factors, cytokines, and specific hormones, that are critically involved in initiating, coordinating, and executing the biological processes of cellular regeneration and structural restoration following injury or metabolic stress. These molecules orchestrate the sequential phases of inflammation, proliferation, and remodeling, ensuring the damaged tissue is effectively replaced or repaired to maintain organ and systemic integrity. Optimizing the availability and signaling of these molecules is a core tenet of restorative medicine.
