I. Core Mechanism of Action

II. Four Major Research-Validated Efficacies

1. Accelerate cell migration and facilitate wound tissue repair

    

   Promote directional migration of keratinocytes, fibroblasts and vascular endothelial cells;

    

   Shorten the healing cycle of skin and soft tissue wounds in animal injury models;

    

   Regulate matrix metalloproteinases to promote ordered collagen deposition and reduce the risk of scar hyperplasia.
2. Induce angiogenesis and improve microcirculation in damaged tissues

    

   Upregulate the expression of Vascular Endothelial Growth Factor (VEGF) by 2.5 to 3.8 times;

    

   Stimulate proliferation and sprouting of microvascular endothelial cells to form new microvessels at injured sites and boost local blood and oxygen supply.
3. Anti-inflammatory and anti-fibrotic effects

    

   Block the canonical NF-κB inflammatory pathway, reduce the release of pro-inflammatory factors such as TNF-α and IL-8, and relieve swelling and chronic inflammation at damaged areas;

    

   Inhibit excessive collagen accumulation to mitigate post-injury tissue sclerosis, fibrosis and scar thickening.
4. Cytoprotection and reduction of oxidative stress-induced apoptosis

    

   Activate the Akt cell survival pathway to resist oxidative damage caused by free radicals, ultraviolet radiation and ischemia, and lower cell apoptosis rates;

    

   It exerts cytoprotective effects on skeletal muscle, tendons, ligaments, cardiac muscle and epidermal epithelial cells.

III. Specific Research Application Fields (Laboratory Use Only)

• Skin research: In vitro models for skin wound repair, epidermal barrier recovery and UV photodamage
• Sports soft tissue research: Animal experiments on the repair of strained or torn tendons, ligaments and skeletal muscle
• Cardiovascular research: Exploration of tissue repair mechanisms after myocardial ischemia and myocardial infarction
• Ophthalmic research: In vitro models for corneal epithelial damage repair
• Combined research: Frequently tested in combination with BPC-157. The two substances feature complementary action pathways and deliver synergistic benefits for tissue regeneration.
