  • Publication number: 20190055517
    Abstract: This invention provides a cell line of M2C macrophage and its applications. The cell line is derived from monocytes isolated from bone marrows and peripheral blood. The monocytes were differentiated into M2 macrophage by macrophage colony-stimulating factor (M-CSF), and then the polarization of M2C macrophage was induced by baicalin. The MERTK, PTX3, and PD-L1 expression level of the M2C macrophage are high and promote phagocytosis. Hence it can be applied to cell therapy or biological agents of immune regulation. Also, the macrophage-conditioned medium and wound dressing prepared on the M2C cell have the effects of enhancing fibroblast proliferation and angiogenesis, which can improve wound healing in medical use, and can be applied to skin care product for skin repair and rejuvenation.
