Figure Lengend Snippet: Immunocytochemical analysis of S100β, MBP, GFAP (red) as well as p75 NGFR and MOG (green) in differentiated and undifferentiated hWJMSCs. Cell nuclei were counterstained with DAPI (blue). Undifferentiated hWJMSCs served as a negative control, while Schwann cells acted as a positive control. hWJMSCs differentiated with 1200 μg/ml RECA showed prominent expression of all neural-specific markers compared to differentiated hWJMSCs in other induction groups ( n = 6). DAPI; 4′, 6-diamidino-2-phenylindole. Scale bar 100 μm

doi: 10.3389/fimmu.2019.01075

Figure Lengend Snippet: PMNs reallocate and cluster with ASCs in knees with early CiOA after intra-articular ASC injection. (A,B) Intra-articular injection on day 7 of CiOA resulted in attraction of immune cells within 6 h, both in the control (A) and ASC-injected (B) joints, as was shown in HE-stained total knee joint sections. (C,D) Higher magnifications showed that the immune cells in both saline- (C) and ASC-injected (D) CiOA knee joints had a polymorphonuclear (PMN) phenotype. (E,F) Immunohistochemistry with the specific antibody NIMP-R14 confirmed that a large number of PMNs is attracted to the joints. They were equally spread throughout the synovium and the joint cavity in the control-injected joints (E) , but in the ASC-injected joints a remarkable accumulation of PMNs along the lining was found (F) as indicated by arrows. (G) NIMP-R14 staining showed that 24 h after ASC injection the PMN influx had largely disappeared. (H) ASC injection in naïve joints resulted in NIMP-R14 positive cell influx, albeit lower than in CiOA joints. (I) Quantification of attracted PMNs after intra-articular injection confirmed a significantly increased number of PMNs in CiOA joints compared to naïve joints. (J) At higher magnification we observed a clustering of PMNs around cells we supposed to be ASCs (arrow), which was confirmed with a CD271 antibody (K) which specifically stains ASCs (arrows). Control joints were CiOA knees injected with saline supplemented with 1% BSA. Images shown are representative for the treatment groups ( n = 8 per group). Original magnification × 200 (A,B,E,F,G,H) or × 1,000 (C,D,J,K) . Differences between groups were tested using a one-way ANOVA followed by a Bonferroni Multiple Comparison posttest. F, femur; S, synovium. Bars show mean values ± SD. * P < 0.05.
