The most studied mechanisms include: upregulation of growth hormone receptors in fibroblasts (increasing sensitivity to healing signals), activation of the FAK-paxillin pathway (promoting cell adhesion and migration), modulation of the nitric oxide system through Src-Caveolin-1-eNOS phosphorylation (enhancing vascular function), and dual activation of the Egr-1/NAB2 gene loop (promoting organized, non-chaotic blood vessel growth)
There's no strong evidence of receptor desensitization with continuous use, but periodic breaks remain standard practice in most clinical protocols
