Identification of the different polarized subtypes from IPSDM. (a) Representative bright-filed images of M0 (left panel), M1 (middle panel), and M2 cells (right panel) from hiPSCs. Scale bars, 100 μm. (b) Flow cytometric analysis of markers CD45, CD14, CD11b, CD80 (M1), CD86 (M1), CD163 (M2), and CD206 (M2) of IPSDMs and PBDMs. (c, d) Flow cytometric analysis of the uptake of fluorescent beads by subtypes of IPSDMs and PBDMs. All experiments were performed three times. Error bars, SD. (e) Flow cytometric analysis of phagocytosis of IPSDM and PBDM subtypes on Nalm6 (labeled with Hoechst 33342) and Reh (labeled with Hoechst 33342) (). Phagocytosis index: the percentage of V450+ macrophages multiplied by the MFI of V450. Error bars, SD. (f) Concentration of IL-6, IL-10, and TNF-α in the supernatants of M0, M1, and M2 cells after 48-hour polarization. .
