R&D Systems anti human ctgf antibody
Connective tissue growth factor expression in synovial tissue of patients with rheumatoid arthritis. The representative results of HE staining (Figure 2A), immunofluorescence <t>anti-CTGF</t> antibody staining (Figure 2B; green), and anti-F4/80 antibody staining (Figure 2C; red) are shown using surgical samples from RA and OA patients. The samples were counterstained by DAPI (blue) for nuclear staining and merge images are shown (Figure 2D). A strong expression of CTGF and F4/80 was observed in the samples of RA compared to OA and the CTGF expression cells were not overlapped with F/40 expression cells indicating that CTGF is upregulated in synovial fibroblasts rather than macrophages.

A) Schematic of lung epithelial development. As the airways extend, bud tip progenitors are maintained as progenitors in the tips of branching buds, and leave cells behind that give rise to the intrapulmonary airways. Late in development, remaining bud tip progenitors differentiate into alveolar cells. No bud tip progenitors are present in the adult lung. B) Schematic of creation of epithelium-only bud tip progenitor organoids from 12 week fetal lungs. C) Feature plots for bud tip progenitor marker genes SFTPC, ID2 and HMGA1 from scRNA-seq of day 0 bud tip progenitor organoids maintained for 3 weeks in culture. Additional feature plots from this same data set are shown in Figure 4A. D) mRNA expression by QRT-PCR of basal cell marker TP63 in bud tip progenitor organoids treated for 3 days with serum-free basal medium supplemented with DMSO (control) or with signaling factors known to be important for lung development and cellular differentiation. DMSO (1:1,000 dilution), FGF7 (10 ng/mL), ‘3F’ (FGF7 10ng/mL, CHIR99021 3μM, ATRA 50 nM), Dexamethasone (25 ng/mL), IL6 (10 ng/mL), <t>IL2</t> (50 U/mL), Smoothened Agonist (SAG; 500 nM), EGF (100 ng/mL), FGF10 (500 ng/mL), CHIR99021 (2 μM), IFNγ (10 ng/mL), TGFβ1 (100 ng/mL), BMP4 (100 ng/mL), DAPT (10 μM), Hydrocortisone (100 ng/mL). Gene expression is reported as arbitrary units. Treatment with TGFβ1 led to a significant increase in the expression of TP63 (one-way Analysis of Variance (ANOVA) (alpha=0.05, p<0.0001, F=14.7. Dunnett’s test of multiple comparison’s compared the mean of each group to the mean of the DMSO control group.) Estimated p values are shown on the graph. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment. E) Bud tip progenitor organoids were treated with FGF7 (10 ng/mL), a permissive environment for TP63 expression compared to maintenance in bud tip progenitor medium (‘3F’), or with FGF7 (10 ng/mL) plus factors to inhibit SMAD signaling (A8301 [1 μM] and NOGGIN [100 ng/mL]) and TP63 gene expression was evaluated by QRT-PCR after 10 days in culture. A one-way Analysis of Variance was used followed by Tukey’s multiple comparison test to compare the means of each group to the mean of every other group. Estimated p values are reported on the graph. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment. F) Bud tip progenitor organoids were treated for 3 days with SMAD activation or inhibition conditions and expression of TP63 was evaluated by QRT-PCR for all treatment groups. All media contained 3F components (FGF7 10ng/mL, CHIR99021 3μM, ATRA 50 nM), with individual groups containing combinations of: DMSO (1:1000 dilution), TGFβ1 (100 ng/mL), BMP4 (100 ng/mL), SB431542 (10 μM), LDN212854 (200 nM). One-way ANOVA alpha=0.05, F=21.19, p<0.0001; Tukey’s multiple comparisons of the mean of each group versus the mean in all other groups, estimated p values are reported on the graph. 3 days TGFβ1 and BMP4 is referred to as ‘dual SMAD activation’, or ‘DSA’. Data is plotted as arbitrary units. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment and is representative of n=3 experiments. G) QRT-PCR for markers of canonical differentiated lung epithelial cell types showing DMSO (gray bars) and DSA treated (blue bars) organoids after 3 total days of treatment. Data is plotted as fold change over DMSO controls. Two-sided Mann-Whitney Tests were performed to compare the mean of the DMSO group to the Dual Smad Activation group (alpha=0.05). Error bars represent the mean +/− the standard error of the mean. n=3 independent biological specimens, and data is from a single experiment and is representative of n=3 experiments. H) Protein staining of DMSO treated (control) fetal bud tip progenitor organoids (top row) and 3 days of DSA treatment (bottom row) for TP63+ protein (green), KRT5 (pink) and DAPI (blue). Scale bar represents 50 μm. I) Quantification of (g). Total number of TP63+ cells were counted for 3–9 individual organoids across 3 biological replicates. n=3 independent biological specimens. A two-sided Mann Whitney test (alpha=0.05) was used to compare the means of each sample. For all graphs, p values are reported as follows: * p<0.05; ** p<0.01, *** p<0.001, **** p<0.0001.

Connective tissue growth factor expression in synovial tissue of patients with rheumatoid arthritis. The representative results of HE staining (Figure 2A), immunofluorescence anti-CTGF antibody staining (Figure 2B; green), and anti-F4/80 antibody staining (Figure 2C; red) are shown using surgical samples from RA and OA patients. The samples were counterstained by DAPI (blue) for nuclear staining and merge images are shown (Figure 2D). A strong expression of CTGF and F4/80 was observed in the samples of RA compared to OA and the CTGF expression cells were not overlapped with F/40 expression cells indicating that CTGF is upregulated in synovial fibroblasts rather than macrophages.

Synergistic effects of connective tissue growth factor on M-CSF/sRANKL-mediated osteoclastic function. Figure 5A shows the results of the resorption of osteoclasts on calcium phosphate. Vacant regions indicated by arrows represent the areas where the osteoclasts actually absorbed. There was no vacant region in negative control cells (M-CSF alone). In contrast to negative control, significant vacant regions were observed in osteoclasts induced by M-CSF/sRANKL. CTGF further expanded the vacant areas in combination with M-CSF/sRANKL and anti-CTGF antibody neutralized this effect. Figure 5B shows the levels of expression of osteoclasts specific proteases (MMP-9 and cathepsin-K) measured by quantitative real time RT-PCR. Synergistic effect of CTGF was also observed for M-CSF/sRANKL-mediated osteoclastogenesis. Bars in Figure 5B indicate the SD.

Connective tissue growth factor mediate ERK1/2 and focal adhesion kinase activation through integrin αVβ3 signal transduction. Figure 6A shows the immnoprecipitation and immunoblotting analysis. The cell extracts of osteoclasts stimulated with recombinant CTGF (10 or 50 ng/ml) at 60 minutes were precipitated using anti-integrin αVβ3 antibody and subsequently blotted with anti- phosphorylated ERK1/ERK2, conventional ERK1/ERK2, and integrin αVβ3 antibodies respectively. The phosphorylated ERK1/ERK2 was recruited with integrin αVβ3 by CTGF stimulation. Figure 6B shows the immunoblotting analysis using anti- phosphorylated FAK, conventional FAK, and β-actin antibodies in the osteoclasts extracts treated with CTGF (10 ng/ml) at 5, 15, 60, and 120 minutes in the presence or absence of anti-CTGF antibody (1 μg/ml). CTGF stimulation resulted in phosphorylation of FAK from 60 minutes and this effect was neutralized by anti-CTGF antibody suggesting activation of signal transduction pathways through integrin αVβ3.

Immunostaining of original tumor, low passage, and high passage KCI-MENG1 cells. The original patient-derived tumor ( top row ) showed moderate and patchy immunoreactivity for epithelial membrane antigen (EMA); strong and diffuse immunostaining for progesterone receptor (PR); and a Ki-67 proliferative index of 2–3%. There was also strong immunostaining for N-cadherin and vimentin. KCI-MENG1-LP cells ( middle row ) and KCI-MENG1-HP cells ( bottom row ) maintained expression of EMA, N-cadherin, and vimentin but had significantly reduced PR expression compared to the original tumor. Whereas Ki-67 labeling was found in only a small number of cells in the original tumor and low passage cells, it was positive in virtually all P84 cells. Scale bar 50 µm.

A In resting cells and under normal physiological conditions, CUL1 interacts with NLRP3 to disrupt the NLRP3 inflammasome assembly, and catalyzes NLRP3 ubiquitination to repress the NLRP3 inflammasome activation. B In response to and inflammasome stimuli and pathogen infection, CUL1 disassociates from NLRP3 to release the repression of NLRP3 inflammasome assembly and activation. ASC binds NLRP3 to form ASC oligomers, which provides a platform for activation of pro-Casp-1 that regulates the maturation and secretion of IL-1β and IL-18, which in turn initiate multiple signaling pathways and drive inflammatory responses.

A) Schematic of lung epithelial development. As the airways extend, bud tip progenitors are maintained as progenitors in the tips of branching buds, and leave cells behind that give rise to the intrapulmonary airways. Late in development, remaining bud tip progenitors differentiate into alveolar cells. No bud tip progenitors are present in the adult lung. B) Schematic of creation of epithelium-only bud tip progenitor organoids from 12 week fetal lungs. C) Feature plots for bud tip progenitor marker genes SFTPC, ID2 and HMGA1 from scRNA-seq of day 0 bud tip progenitor organoids maintained for 3 weeks in culture. Additional feature plots from this same data set are shown in Figure 4A. D) mRNA expression by QRT-PCR of basal cell marker TP63 in bud tip progenitor organoids treated for 3 days with serum-free basal medium supplemented with DMSO (control) or with signaling factors known to be important for lung development and cellular differentiation. DMSO (1:1,000 dilution), FGF7 (10 ng/mL), ‘3F’ (FGF7 10ng/mL, CHIR99021 3μM, ATRA 50 nM), Dexamethasone (25 ng/mL), IL6 (10 ng/mL), IL2 (50 U/mL), Smoothened Agonist (SAG; 500 nM), EGF (100 ng/mL), FGF10 (500 ng/mL), CHIR99021 (2 μM), IFNγ (10 ng/mL), TGFβ1 (100 ng/mL), BMP4 (100 ng/mL), DAPT (10 μM), Hydrocortisone (100 ng/mL). Gene expression is reported as arbitrary units. Treatment with TGFβ1 led to a significant increase in the expression of TP63 (one-way Analysis of Variance (ANOVA) (alpha=0.05, p<0.0001, F=14.7. Dunnett’s test of multiple comparison’s compared the mean of each group to the mean of the DMSO control group.) Estimated p values are shown on the graph. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment. E) Bud tip progenitor organoids were treated with FGF7 (10 ng/mL), a permissive environment for TP63 expression compared to maintenance in bud tip progenitor medium (‘3F’), or with FGF7 (10 ng/mL) plus factors to inhibit SMAD signaling (A8301 [1 μM] and NOGGIN [100 ng/mL]) and TP63 gene expression was evaluated by QRT-PCR after 10 days in culture. A one-way Analysis of Variance was used followed by Tukey’s multiple comparison test to compare the means of each group to the mean of every other group. Estimated p values are reported on the graph. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment. F) Bud tip progenitor organoids were treated for 3 days with SMAD activation or inhibition conditions and expression of TP63 was evaluated by QRT-PCR for all treatment groups.

One-way ANOVA alpha=0.05, F=21.19, p<0.0001; Tukey’s multiple comparisons of the mean of each group versus the mean in all other groups, estimated p values are reported on the graph. 3 days TGFβ1 and BMP4 is referred to as ‘dual SMAD activation’, or ‘DSA’. Data is plotted as arbitrary units. Error bars are plotted to show mean +/− the standard error of the mean. N=3 independent biological specimens. Data is from a single experiment and is representative of n=3 experiments. G) QRT-PCR for markers of canonical differentiated lung epithelial cell types showing DMSO (gray bars) and DSA treated (blue bars) organoids after 3 total days of treatment. Data is plotted as fold change over DMSO controls. Two-sided Mann-Whitney Tests were performed to compare the mean of the DMSO group to the Dual Smad Activation group (alpha=0.05).
