Growth Factor Biology
The response of living tissue to injury forms the foundation of all surgical practice: 
- All surgery results in tissue and cellular damage
- The body's natural response to this injury is a series of regeneration
and remodeling steps collectively referred to as the "Healing
Cascade"
- The steps are initiated and controlled by bioactive proteins found
in platelets, plasma, and white blood cells
- Cellular regeneration, remodeling, and proliferation required a combination
of:
- Scaffold (structure or matrix)
- Undifferentiated Cells
- Signal Proteins (platelets, plasma and white blood cells)
- Increasing the concentration of the bioactive proteins acts as a catalyst
for accelerating the wound healing process and forms the foundation
of tissue engineering
