Fibronectin and wound healing.

F Grinnell

    Journal of Cellular Biochemistry
    |January 1, 1984
    PubMed
    Summary

    Fibronectin is crucial for skin wound healing, aiding cell migration and tissue organization. However, it may also increase infection risk by promoting bacterial attachment in wounds.

    Area of Science:

    • Biochemistry
    • Cell Biology
    • Dermatology

    Background:

    • Fibronectin is a key extracellular matrix protein involved in various cellular processes.
    • Its role in cutaneous wound healing is significant, influencing multiple stages of the repair process.

    Purpose of the Study:

    • To review the evidence supporting fibronectin's importance in cutaneous wound healing.
    • To explore fibronectin's multifaceted roles from initial injury to tissue remodeling.

    Main Methods:

    • Review of existing scientific literature and experimental data on fibronectin in wound healing.
    • Summarization of evidence presented in Table II.

    Main Results:

    • Fibronectin promotes platelet spreading, immune cell and fibroblast migration, and epidermal cell migration.
    • It is involved in granulation tissue and basement membrane organization.
    • Fibronectin acts as an opsonin for debris phagocytosis but may enhance bacterial attachment and infection.

    Conclusions:

    • Fibronectin plays a central role in cutaneous wound healing and likely in the repair of internal tissues.
    • Factor XIII deficiency may impair wound healing due to impaired fibronectin incorporation into clots.
    • The dual role of fibronectin, promoting healing while potentially increasing infection risk, warrants further investigation.
