Foreign body reaction (FBR), an immune-mediated complex healing process, plays a crucial role in integrating implants into the body. Macrophages, as the first line of immune system interaction with implant surfaces, play a bidirectional role in modulating the inflammation-regeneration balance. For a deep understanding and the evaluation of the reactions between implant materials and immune responses, reliable in vitro methods and protocols are pivotal. Among different in vitro models, primary monocyte-derived macrophages (MDMs) present an excellent model for investigating macrophage-implant interactions. We have implemented an experimental protocol to evaluate the polarization of MDMs into M1 (classically activated) and M2 (alternatively activated) macrophages on implant surfaces. We isolated blood monocytes from healthy donors and differentiated them into macrophages using macrophage colony-stimulating factor (M-CSF). Differentiated macrophages were cultured on implant surfaces and polarized into M1 and M2 subtypes. M1 polarization was achieved in the presence of interferon (IFN)-γ and lipopolysaccharide (LPS), while M2 polarization was performed in a medium containing interleukin (IL)-4 and IL-13. We evaluated macrophage phenotypes by Enzyme-linked Immunosorbent Assay (ELISA), confocal laser scanning microscopy (CLSM), and quantitative real-time PCR (qRT-PCR) based on panels of secreted cytokines, cell surface markers, and expressed genes. The extracted RNA was transformed into complementary DNA (cDNA), and qRT-PCR was used to quantify mRNA related to M1 and M2 macrophages. Accordingly, M1 macrophages have been characterized by higher expression of proinflammatory Tumor necrosis factor (TNF-α) cytokine and CCR7 surface marker compared to M2 macrophages, which exhibited higher levels of CD209 and CCL13. Consequently, CCR7 and CD209 were identified as specific and reliable markers of M1 and M2 macrophage subtypes by immunostaining and visualizing by CLSM. Further confirmation was achieved by ELISA detecting elevated TNF-ɑ level in M1 and increased CCL13 in M2 cells. The proposed markers and experimental setup can be used effectively to assess the immunomodulatory potential of implants.
