Figure Lengend Snippet: Identification, immunogenicity and immunomodulation of huMSCs . (A) The huMSCs cultured in our experiment. The huMSCs were spindle-shaped and grew in a whorl pattern. Original magnification 100×, scale bars: 200 μm. (B) Flow cytometry detection of CD29, CD44, CD73 and CD105. The rate of positive expression for all factors was greater than 95%. (C) Detection of huMSC HLAII expression in PBMCs and huMSCs by western blot. No HLAII expression band was detected in the huMSCs. (D) Relative expression of HLAII in PBMCs and huMSCs. The bar graph shows no HLAII expression in huMSCs. (E) PCR amplification curves of HLA-DPA1 , HLA-DQA1 and HLA-DRA1 genes in PBMCs and huMSCs. (F) Relative expression of HLA-DPA1 , HLA-DQA1 and HLA-DRA1 genes in PBMCs and huMSCs. PCR results showed no expression of HLA-DPA1 , HLA-DQA1 or HLA-DRA1 genes in huMSCs. (G) Expression curves of serum IL-6, IL-10, IL-12, TGF-β, and TNF-α detected by ELISA method ( n = 5 rats per group). Compared with the TBI group, the serum pro-inflammatory cytokines IL-6, IL-12 and TNF-α in the Tail Vein and In Situ group were lower (### P < 0.001), whereas the inflammation inhibiting factors IL-10 and TGF-β were much higher (### P < 0.001), indicating that huMSCs exert good immunoregulatory effects. Data are expressed as the mean ± SD. *** P < 0.001, vs . PBMCs (one-way analysis of variance followed by least significant difference test). ELISA: Enzyme-linked immunosorbent assay; GAPDH: glyceraldehyde 3-phosphate dehydrogenase; HLAII: human leukocyte antigen II; huMSCs: human umbilical cord mesenchymal stem cells; IL: interleukin; PBMCs: peripheral blood mononuclear cells; PCR: polymerase chain reaction; TBI: traumatic brain injury; TGF-β: transforming growth factor beta; TNF-α: tumor necrosis factor alpha.

Article Snippet: The sections were thereafter incubated overnight at 4°C with primary antibodies, including rabbit anti-human CD29 polyclonal antibody (Cat# PB9086, 1:100, Boster), proliferating cell nuclear antigen (PCNA) mouse monoclonal antibody (Cat# 2586S, 1:4000, CST, Danvers, MA, USA), Caspase 3 (CASP3) rabbit polyclonal antibody (Cat# 19677-1-AP, 1:200, Proteintech) and F4/80 rabbit polyclonal antibody (Cat# 28463-1-AP, 1:200, Proteintech), diluted in 1% bovine serum albumin containing PBS.

Figure Lengend Snippet: Sites of accumulation of huMSCs in vivo in TBI rats . (A) Live imaging of the primary organs of experimental rats. (B, C) The average fluorescence intensity in the brain, liver and lung in the In Situ (B) and Tail Vein (C) groups. Data are expressed as the mean ± SD ( n = 5 rats at each time point). # P < 0.05, ## P < 0.01, vs . TBI group (one-way analysis of variance followed by least significant difference test). (D, E) CD29 (red, stained by CoraLite594) immunoreactivity in CFSE-labeled huMSCs in brain tissue (immunofluorescence staining, original magnification 200×, scale bars: 100 μm). CD29 and CFSE co-labeled huMSCs were identified in the In Situ group on days 1, 3 and 7 (D) in the brain lesions. A few CFSE-labeled huMSCs in the Tail Vein group were also observed in the brain lesions on days 1 and 3 (E). CFSE: Carboxyfluorescein succinimidyl ester; CON: TBI group; DAPI: 4′,6-diamidine-2′-phenylindole dihydrochloride; huMSCs: human umbilical cord mesenchymal stem cells; TBI: traumatic brain injury.

Figure Lengend Snippet: Aa, Ab, and Ac show integrin β1 expression at 2 post-graft weeks (PGWs) in groups II,III, and IV, respectively, in Experiment A. Ad shows integrin β1 expression in the hair follicle in group IV in Experiment A. Ae and Af show integrin β1 expression at 2 PGWs in groups II and III, respectively, in Experiment B. Ag and Ah show expression of integrin β1 in the hair follicle and no expression of integrin β1 in the epidermis, respectively, of normal Sprague-Dawley (SD) rat skin. Ai, Aj, and Ak show negative control staining of 2 PGW sections from groups II, III, and IV, respectively, in Experiment A. Scale bar, 50 µm in Aa–Ah and 100 µm in Ai–Ak. In Experiment A, the mean integrated optical density (IOD) of integrin β1 expression at 2 PGWs was higher in groups III and IV than in group II (* p<0.05), and, more interestingly, was highest in group III among these 3 groups (* p<0.05, # p<0.05). At 3 and 4 PGWs, the integrin β1 expression remained higher in group III than in groups II and IV (* p<0.05, # p<0.05). In Experiment B, the integrin β1 expression at 2 PGWs was stronger in group III than in group I (* p<0.05), and no intergroup difference was found at 4 PGWs.

Article Snippet: The sections were then sequentially incubated with normal goat serum for 40 minutes to block nonspecific binding, with the primary rabbit anti-integrin β1 polyclonal antibody (1∶100, Wuhan Boster Biological Technology LTD, Hubei, China) for 15 hours at 4°C, and with the SABC kit (Wuhan Boster Biological Technology, LTD, Hubei, China) at 37°C to bind the primary antibody.
