Growth Factors

Growth factors are highly specialized, bioavailable protein molecules that play a pivotal role in regulating many essential biological processes within the human body. These proteins act as cell signaling molecules, controlling cell division, differentiation, survival, and migration, making them crucial for maintaining homeostasis and repairing tissues.

What are the growth factors?

Growth factors are short proteins or peptides that bind to specific receptors on the cell surface, activating internal signaling pathways that control gene expression and cell function. Some of the most well-known of these factors include:

•  EGF (Epidermal Growth Factor) is responsible for stimulating the growth of epithelial cells and the regeneration of surface tissues.
•  FGF (Fibroblast Growth Factor) is involved in blood vessel formation, wound healing, and connective tissue growth.
• PDGF (Platelet-Derived Growth Factor) plays a key role in tissue repair and activation. Fibroblasts.
•  VEGF (Vascular Endothelial Growth Factor) is a key stimulator for the formation of new blood vessels.
•  NGF (Nerve Growth Factor) is essential for the growth and survival of nerve cells.

Methods of using Growth Factors

• Growth factors are extracted either from platelet-rich plasma (PRP) or from laboratory-prepared medical preparations.
• It is used topically, by injection, or in combination with other treatment techniques according to precise medical protocols.

Dosage of Growth Factors

The dosage is determined according to the type of preparation, the concentration of growth factors, and the condition of the tissue, and is decided by the doctor after medical evaluation.

The onset of the effectiveness of growth factors

Results appear gradually over 2–4 weeks as a result of cell regeneration activation.

Duration of effectiveness

It lasts from 3 to 6 months depending on the case and the number of sessions.

Nutrition

No special restrictions, and a balanced diet is recommended to support cell regeneration.

Storage and preservation

• Store at appropriate temperatures, away from heat and light.
• It is necessary to ensure that the product is medically approved.

Forgetting the follow-up session

It can be rescheduled without harm, with the possibility of a delay to the ideal result.

Stop treatment with growth factors

Stopping growth factor sessions does not cause damage to the tissue, but the cellular stimulation processes gradually decline, and the tissue returns to its normal biological state over time.

overdose

• Uncontrolled use may lead to excessive cellular stimulation or local inflammatory responses.

Warnings regarding the use of growth factors

• The products should be stored at low temperatures according to the manufacturer's instructions.
• They must be protected from direct light and heat to maintain protein stability.
• It is necessary to verify the source of the product and its medical approval before use.
