Factor XIII inhibits epidermal cell migration in vitro.

T Hashimoto, R Marks

    The Journal of Investigative Dermatology
    |December 1, 1984
    PubMed
    Summary

    Factor XIII preparation inhibits epidermal cell migration and proliferation in vitro. This dose-dependent effect occurs independently of fibrin or calcium ion concentration, impacting skin cell activity.

    Area of Science:

    • Dermatology and Cell Biology
    • Biochemistry and Molecular Biology

    Background:

    • Epidermal cell migration is crucial for skin wound healing and tissue regeneration.
    • Factor XIII is a protransglutaminase essential for stabilizing fibrin clots and tissue repair.

    Purpose of the Study:

    • To investigate the in vitro effect of a Factor XIII preparation on human epidermal cell migration.
    • To assess the impact of Factor XIII on epidermal cell proliferation.

    Main Methods:

    • Utilized short-term maintenance cultures of both floating and attached human skin explants.
    • Assessed epidermal cell migration and proliferation in response to varying concentrations of Factor XIII preparation.

    Main Results:

    • Factor XIII preparation demonstrated a dose-dependent inhibition of epidermal cell migration in vitro.
    • The inhibitory effect on migration was observed irrespective of fibrin presence or calcium ion concentration.
    • Factor XIII preparation also inhibited epidermal cell proliferation in cell culture.

    Conclusions:

    • Factor XIII preparation exerts an inhibitory influence on key cellular processes in epidermal cells, including migration and proliferation.
    • These findings suggest a potential regulatory role of Factor XIII in skin cell dynamics beyond its known function in hemostasis.
