Figure Lengend Snippet: Deficiency of HCK leads to insufficient phagocytosis of macrophages. (A) The PM cells of patients with or without EMs were incubated with carboxylate‐modified fluorescent latex beads for 1 h (number of macrophages: number of beads = 1:100). Phagocytosis ratio was detected by FCM and calculated as the percentage of CD14 + FITC + cells among CD14 + macrophages. (B) Validation of HCK silenced THP1 cell lines using Western blotting or RT‐PCR. (C, D) HESCs were labelled with PKH26 and co‐cultured with NC ( n = 3) or HCKi ( n = 3) M2 macrophages for 2 h (number of macrophages: number of HESCs = 1:2). Phagocytosis ratio was detected by FCM and calculated as the percentage of PKH26 + macrophages among total macrophages. (E–H) Chicken erythrocytes (CRBC) were labelled with PKH26 and co‐cultured with NC ( n = 3) or HCKi ( n = 3) M2 macrophages (E and G) or PM cells of Hck −/− mice ( n = 4) or WT mice ( n = 4) (F and H) for 1 h (number of macrophages: number of chicken erythrocytes = 1:10). Macrophages labelled with DAPI. Phagocytosis was detected by fluorescence microscopy. The phagocytic index calculated as the percentage of phagocyted chicken erythrocytes among total macrophages (Scale bar, 100 μm). (I–L) The PM cells of Hck −/− mice ( n = 4) or WT mice ( n = 4) were incubated with carboxylate‐modified fluorescent latex beads for 1 h (number of macrophages: number of beads = 1:100). Phagocytosis was detected by fluorescence microscopy (I, J) or FCM (K, L) (Scale bar, 25 μm). Data were presented as mean ± SEM and analysed by t test. * p < 0.05; **p < 0.01; *** p < 0.001. EM, endometriosis; FCM, flow cytometry; HCK, haematopoietic cellular kinase; HCKi, HCK‐silenced; HESC, human endometrial stromal cells line; NC, normal control THP‐1 cells; PM, peritoneal macrophages.
Article Snippet: The PF cells, isolated from PF of both the control group and patients with EMS, were collected to isolate macrophages with MASC, a human/mouse CD14 + cell isolation kit (130‐050‐201, Miltenyi Biotec, Germany) for in vitro experiments.
