What is the Origin of Trophic Factor Administration?

The concept originates from developmental biology and neuroscience, where trophic factors were first identified as essential for the survival and growth of neurons. In clinical endocrinology, the focus shifted to their systemic role in maintaining tissue homeostasis and combating age-related decline, such as sarcopenia and cognitive impairment. The term 'trophic' itself means "relating to nutrition or nourishment."

What is the Mechanism of Trophic Factor Administration?

Trophic factors exert their effects by binding to high-affinity tyrosine kinase receptors on the cell surface, initiating complex intracellular signaling cascades, most notably the PI3K

Trophic Factor Administration

Meaning

Trophic Factor Administration is the therapeutic introduction of naturally occurring signaling molecules, primarily peptides or proteins, that support the survival, differentiation, and function of specific cell populations. These factors, such as Growth Hormone (GH) or Brain-Derived Neurotrophic Factor (BDNF), act to promote tissue repair, neurogenesis, and cellular longevity by preventing apoptosis and stimulating regenerative processes. This approach is a core strategy in regenerative and anti-aging medicine.
