Article Title: Differentiation of adipose-derived stem cells into Schwann cell-like cells through intermittent induction: potential advantage of cellular transient memory function.

doi: 10.1186/s13287-018-0884-3

Figure Lengend Snippet: Fig. 1 Identification of adipose-derived stem cells (ASCs) and schematic of the experimental design. a Primary ASCs grew in clusters and had a rounded spindle-like shape. b ASCs at passage 2 could differentiate into adipocytes, and the visual field in photographs was filled with red lipid droplets stained with Oil Red O solution. c ASCs differentiated into osteocytes formed calcium nodules with burrs, which were stained red by Alizarin Red solution. d In cartilage pellets, many cartilage lacunae were found, and the glycosaminoglycans around the chondrocytes were stained purple-blue by Toluidine Blue O solution. e Flow cytometry showed that more than 98% of ASCs were immunopositive for the MSC markers CD29, CD44, and CD90, while less than 6% of ASCs were immunopositive for the hematopoietic stem cell markers CD34, CD45, and CD86. f Schematic showing the experimental groups and induction methods. bFGF, basic fibroblast growth factor; β-ME, β-mercaptoethanol; dASC, differentiated ASC; DMEM, Dulbecco’s modified Eagle’s medium; FBS, fetal bovine serum; PDGF, platelet-derived growth factor; SC, Schwann cell; uASC, undifferentiated ASC

Article Snippet: Pre-induction medium I was replaced with pre-induction medium II consisting of DMEM, 10% FBS, and 35 ng/ml all trans-retinoic acid (RA) (R2625; Sigma) and incubated for 72 h. The resulting differentiated ASCs were divided into four groups according to subsequent processing: (ii) sustaining dASCs 4d: Differentiated ASCs (dASCs) were induced for 4 days with complete induction medium consisting of DMEM, 10% FBS, 5 μM forskolin (F6886; Sigma), 200 ng/ml recombinant human heregulin-β1 (HRG) (100–03; PeproTech), 10 ng/ml basic fibroblast growth factor (bFGF) (3339-FB: R&D Systems), and 5 ng/ml recombinant rat plateletderived growth factor (PDGF)-AB (1115-AB; R&D Systems); (iii) sustaining dASCs 7d: dASCs were induced for 7 days with complete induction medium; (iv) sustaining dASCs 10d: dASCs were induced for 10 days with complete induction medium; (v) intermittent dASCs: dASCs were induced for 4 days with complete induction medium, after which complete induction medium was replaced with incomplete induction medium consisting of DMEM, 10% FBS, 5 μM forskolin, and 200 ng/ml HRG for induction for 3 days.

Figure Lengend Snippet: Figure 3. Gal-1 (galectin-1) is induced by TNFα (tumor necrosis factor alpha) and enhances TNFα-induced MMP (matrix metalloprotease)-9 expression. A, Cultured vascular smooth muscle cells (VSMCs) and adventitial fibroblasts were treated without (control [ctrl]) or with Ang II (angiotensin II; 100 nmol/L), TNFα (100 ng/mL), or IL (interleukin)-1β (10 ng/mL) as indicated for 48 h. Gal-1 expression in cell lysates was examined by Western blot analysis. B, The Gal-1 levels in culture media collected from treated cells described in A were measured by ELISA. Data shown are mean±SE of 3 independent experiments. *P<0.05 vs ctrl. C, Adventitial fibroblasts isolated from WT (wild type) and Gal-1−/− mice were treated with indicated concentrations of TNFα in culture for 48 h. Culture media were then collected and analyzed by gelatin zymography. Cell lysates were prepared and subjected to Western blot analysis using indicated antibodies. D, WT and Gal-1−/− fibroblasts were treated with TNFα (100 ng/mL) for indicated times. Cell lysates were prepared, and the expression levels of phosphorylated Erk1/2 and total Erk1/2 were examined by Western blot analysis. E, WT and Gal-1−/− fibroblasts were treated with or without TNFα (100 ng/mL) in the absence or presence of PD98095 (10 µmol/L) as indicated in culture for 48 h. Culture media and cell lysates were subjected to zymography and Western blot analysis, respectively.

Figure Lengend Snippet: Figure 4. Gal-1 (galectin-1) oxidation promotes MMP (matrix metalloprotease)-9 and inflammatory cytokine expression. A, Tissue lysates prepared from freshly isolated vessels of apoE-deficient mice were incubated with 2 mmol/L biotin-polyethylene oxide (PEO) iodoacetamide preceded with or without tris(2-carboxyethyl) phosphine hydrochloride (TCEP; 5 mmol/L) treatment at room temperature for 2 h in dark. The lysates were then subjected to immunoprecipitation with control IgG or anti-Gal-1 antibody as indicated. The levels of biotinylation and Gal-1 in cell lysates and immunoprecipitates were examined by streptavidin blotting and Western blot analysis, respectively. B, Cultured macrophages, vascular smooth muscle cells (VSMCs), and adventitial fibroblasts from Gal-1−/− mice were incubated with indicated concentrations of CSGal-1 (cysteine-less Gal-1 mutant) or oxidized Gal-1 (oxGal-1) for 24 (macrophages) or 48 h (VSMCs and fibroblasts). Culture media were harvested and analyzed by zymography. Cell lysates were prepared and subjected to Western blot analysis with MMP9 and β-actin antibodies. C, The levels of TNFα (tumor necrosis factor alpha), IL (interleukin)-6, and MCP-1 (monocyte chemoattractant protein-1) in culture media harvested from treated cells described in B were determined by ELISA. Data shown are mean±SE of 4 independent experiments. *P<0.05; **P<0.01, ***P<0.001 vs control.

Article Title: Serosal Mesothelium Retains Vasculogenic Potential

doi: 10.1002/dvdy.21334

Figure Lengend Snippet: Growth factors induce epithelial–mesenchymal transition (EMT) and smooth muscle actin (SMA) expression in serosal mesothelial cultures. Explants were cultured for 5 days under various conditions and analyzed for expression of Wt1 and SMA. A–C: After culture in normal medium, many peripheral cells of explants are fibroblastic and express SMA but not Wt1 (arrowheads), while Wt1-positive cells are negative for SMA (yellow open arrowhead). D–F: Under serum-free (sf) conditions, few of the epithelial sheet cells of cultured explants express SMA, whereas its majority express Wt1. SMA-positive cells can be Wt1-positive (open arrowheads) and Wt1-negative (arrowheads). G–L: Similar results were obtained for explants grown in sf-medium supplemented with basic fibroblast growth factor (bFGF) or epithelial growth factor (EGF), with few SMA-positive cells in the epithelial sheets. M–O: In explants grown in sf-medium supplemented with platelet-derived growth factor-BB (PDGF-BB), many fibroblastic peripheral cells in the epithelial sheet express SMA (arrowheads), many of which coexpress Wt1 (open arrowheads). Scale bar = 200 μm.

Article Snippet: Growth Factors Growth factors used were recombinant human EGF (40 ng/ml; R&D systems, 236-EG), recombinant human bFGF (40 ng/ml; R&D systems, 234-FSE/CF), and recombinant human homodimer PDGF-BB (40 ng/ml; Chemicon, GF018).

doi: 10.1002/dvdy.21334

Figure Lengend Snippet: Production of smooth muscle actin (SMA) -positive cells in cultures of serosal mesothelium in the presence of specific growth factors. Cultures were analyzed at 5 days of culture with anti-SMA and anti-Wt1 antibodies. The total number of SMA-positive cells at the periphery was determined for each group indicated. One-way analysis of variance analysis determined that the number of SMA-positive cells in control serum-containing cultures was not significantly different from cultures with serum-free (sf) medium supplemented with platelet-derived growth factor-BB (PDGF-BB). In contrast to differentiation in serum-containing conditions, the number of SMA-positive cells in sf-medium or sf-medium supplemented with epithelial growth factor (EGF) or basic fibroblast growth factor (bFGF) was significantly (P < 0.001) reduced.

Article Snippet: Growth Factors Growth factors used were recombinant human EGF (40 ng/ml; R&D systems, 236-EG), recombinant human bFGF (40 ng/ml; R&D systems, 234-FSE/CF), and recombinant human homodimer PDGF-BB (40 ng/ml; Chemicon, GF018).
