Manipulating mechanical forces to regulate inflammation and control scar formation

Stanford researchers have invented a novel concept to prevent or minimize scar formation during injury by controlling the mechanical environment through molecular targeting of mechanotransduction sensors including focal adhesion kinase (FAK).

This new method proposes that mechanical forces initiate and sustain a pro-inflammatory environment after injury through fibroblast-associated pathways. Specific mechanotransduction targets relay these signals to promote scar formation and can be blocked with molecular agents to prevent fibrosis. This paradigm has the potential to establish an entirely new class of clinical devices and therapies to treat scarring.

Stage of Research:
- Completed Large Animal and Phase I clinical trial. Results indicate that mechanical manipulation of the wound environment with a dynamic stress-shielding polymer device can significantly reduce scar formation. See publication link below.
- Ongoing basic science research using mouse and fibroblast models of scarring in the Gurtner laboratory.


HTS model: a) Surface scar formation. n = 6. (b) Images of scars at 10 d after injury. Scale bars, top, 0.5 cm; bottom, 200 ?m. (c) Polarized light and trichrome-stained images. n = 6. Scale bars, 200 ?m; zoom scale bars, 50 ?m. (d) Quantitative RT-PCR (qRT-PCR) analysis of wound cytokines. n = 9. (e) Scar cytokine densitometry. Arrowheads point to the monomer and dimer forms of Tgf-?1. n = 3. (f) Immunolocalization of MCP-1, ?-SMA+ cells and F4/80+ macrophages. Scale bars, left column, 20 ?m; middle and right columns, 50 ?m. n = 6. (g) F4/80+ and CCR2+ flow cytometry. Quadrant values represent the percentage of total scar cells. n = 4. Values are means ± s.e.m. *P 0.05, †P 0.01, ‡P 0.001. The dashed lines outline the scar.
