    Platelet-rich fibrin (PRF) enhances tissue healing by inducing pro-inflammatory macrophage polarization, crucial for the healing process.

  • 2

    U937 cells exhibit a strong inflammatory response to PRF, making them an effective bioassay for studying macrophage activation.

  • 3

    Gene expression analysis in U937 macrophages revealed pathways related to chemokine activity and collagen catabolism upon PRF exposure.

  • 4

    THP-1 cells showed a limited response to PRF, primarily enriching genes involved in steroid biosynthesis.

  • 5

    The study highlights the importance of understanding macrophage responses to PRF for improving regenerative medicine strategies.
