Figure Lengend Snippet: Immunofluorescence images of MAC-T cells. (A) Nucleus staining of MAC-T cells; (B) Cytokeratin 18 (CK18) staining; (C) Combined nucleus and CK18 staining. KSR: Knockout™ serum replacement. ITS: insulin–transferrin–selenium. Scale bar = 200 μm.

Article Snippet: After washed with pre-cooled PBS for 5 min, cells were fixed with 4% paraformaldehyde for 20 min, permeabilized with 0.1% Triton-X-100 for 1 h, and blocked with 5% BSA at room temperature for 2 h. Then primary antibody CK18 (Bioss, bs2043R) diluted at 1:100 was added, followed by overnight incubation at 4 °C and incubation with a fluorescent secondary antibody (Proteintech, RGAR004) at 1:500 dilution in the dark for 2 h. The cells were washed thrice with PBS and stained with DAPI (Beyotime, C1106) ( ).

Article Title: Menstrual blood‐derived mesenchymal stem cells combining with platelet‐rich plasma infusion in endometrium repair

doi: 10.1111/jog.16135

Figure Lengend Snippet: MenSCs + PRP significantly induced the protein expression of CK18, vimentin, and ItgαVβ3 in endometrium. The expressions of CK18 (a), vimentin (b), and ItgαVβ3 (c) were observed using IHC staining (red arrows indicate the positive areas in the immunostaining images), and the average optical density was measured using ImageJ software (d–f). The expressions of CK18, vimentin, and ItgαVβ3 were significantly decreased after ethanol perfusion. MenSCs, PRP, and MenSCs + PRP treatment enhanced CK18, vimentin, and ItgαVβ3 expressions, with MenSCs + PRP showing the most significant effects ( n = 3, # p < 0.05, ## p < 0.01, ### p < 0.001, #### p < 0.0001 vs. control; * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 vs. model; & p < 0.05, && p < 0.01, &&& p < 0.001, &&&& p < 0.0001 vs. MenSCs + PRP).

Figure Lengend Snippet: MenSCs + PRP significantly increased vimentin, CK18, and VEGF expressions in endometrium. The protein expressions in endometrium tissues were determined using WB assay. The vimentin (a), CK18 (b), and VEGF (c) levels were all markedly decreased after modeling, while were significantly increased by MenSCs + PRP, MenSCs, and PRP treatments, with MenSCs + PRP showing the most significant effects ( n = 3, # p < 0.05, ## p < 0.01, ### p < 0.001, #### p < 0.0001 vs. control; * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 vs. model; & p < 0.05, && p < 0.01, &&& p < 0.001, &&&& p < 0.0001 vs. MenSCs + PRP).
