Growth Factors and Cytokines are very important during all three phases of muscle healing. Researchers have suggested that the therapeutic use of Growth Factors and Cytokines has a positive effect on the healing process.
Researchers reported that they had identified three Growth Factors - basic fibroblast growth factor (bFGF), nerve growth factor (NGF) and insulin-like growth factor-1 (IGF1) - which they claimed lead to an increase in the cells responsible for muscle regeneration and improved healing, although there are many more Growth factors and Cytokines.
Further research has revealed that the therapeutic use of Growth Factors and Cytokines in soft tissue injury reduces inflammation, minimises scar tissue formation and promotes the restoration of normal soft tissue.
The conclusion was that getting Growth Factors and Cytokines to the site of soft tissue damage would have a positive effect on healing.
