Figure Legend Snippet: Effect of MTX, PSL, adalimumab, and tocilizumab on MSC differentiation into adipocytes. (A) Typical imaging screening panel for quantification of mFABP4 expression. MSCs were seeded on 96-well plates, and 32 fields were captured in each well using a high-throughput image quantitation system. One of 32 fields is shown. (B, C) The titration curve of mFABP4 expression in MSCs treated with (B) (MTX or PSL, and (C) adalimumab or tocilizumab. The average change of fluorescent intensity was obtained from 96 images for each concentration. Results are presented as mean ± SEM. (D) Typical images of lipid droplets analysis in antirheumatic drug-treated MSCs. Following Oil Red O staining, lipid droplets present as red-stained areas. (E, F) Changes in positive area of lipid droplet in MSCs treated with (E) MTX or PSL, and (F) adalimumab or tocilizumab. The red-stained area was calibrated by the number of nuclei. Results are presented as mean ± SEM. mFABP4, mouse fatty acid binding protein; MSC, mesenchymal stem cell; MTX, methotrexate; PSL, prednisolone; SEM, standard error of the mean.
Techniques Used: Imaging, Expressing, High Throughput Screening Assay, Quantitation Assay, Titration, Concentration Assay, Staining, Binding Assay
Figure Legend Snippet: Osteogenic differentiation potencies of antirheumatic drug-treated MSCs. (A) Typical imaging screening panel for quantification of osteocalcin expression. One of 32 screening panels is shown. (B , C) The titration curve of osteocalcin expression in MSCs treated with (B) MTX or PSL, and (C) adalimumab or tocilizumab. Average change of fluorescent intensity was obtained from 96 images for each concentration. Results are presented as mean ± SEM. (D) Typical images of ALP-activity analysis in antirheumatic drug-treated MSCs. Positive areas present as purple-stained areas (200×; scale bar: 40 μm). (E , F) Changes of relative positive area of ALP-activity assay in MSCs treated with (E) MTX or PSL, and (F) adalimumab or tocilizumab. The purple-stained area was segmented from the background and the change of relative area was quantified. More than four fields per section and an average of five sections for each concentration were used for semiquantitative analysis. Results are presented as mean ± SEM. ALP, alkaline phosphatase; MSC, mesenchymal stem cell; MTX, methotrexate; PSL, prednisolone; SEM, standard error of the mean.
Techniques Used: Imaging, Expressing, Titration, Concentration Assay, Activity Assay, Staining, ALP Activity Assay
Figure Legend Snippet: In vitro chondrogenic assessment of antirheumatic agent-treated MSC-spheroids. (A) Micromass formation by antirheumatic agent-treated spheroids after 28 days of induction culture. (B) Typical images of aggrecan and CD44 expression in MSC spheroids. Fixed micromasses were embedded and sectioned on a cryotome. Expression of aggrecan (green) and CD44 (red) were observed using immunohistochemical staining (200×; scale bar: 40 μm). (C–F) Quantification of volume of micromass formed by chondrospheroids treated with (C) MTX, (D) PSL, (E) adalimumab, and (F) tocilizumab. MRI imaging of micromass was acquired under a three-dimensional T2-weighted flash sequence protocol; coronal and sagittal images were collected and reconstructed to obtain the volume of chondrospheroids. Results are expressed as the mean ± standard deviation (SD) (n=5). MSC, mesenchymal stem cell; MRI, magnetic resonance imaging; MTX, methotrexate; PSL, prednisolone.
Techniques Used: In Vitro, Expressing, Immunohistochemical staining, Staining, Imaging, Sequencing, Standard Deviation, Magnetic Resonance Imaging
Figure Legend Snippet: Establishment an in vivo chondrogenic drug-screening system. (A) Cartilaginous mass formation in chondrospheroid-engrafted mice. Chondrospheroids with and without scaffold were implanted to NOD/SCID mice preengrafted with healthy-donor derived PBMCs. Four weeks later, cartilaginous particles had formed. (B) Typical images of aggrecan and CD44 expression in MSC spheroids before engrafting and 4 weeks after chondrospheroid transplantation. Expression of aggrecan (green) and CD44 (red) were observed using immunohistochemical staining (200×; scale bar: 40 μm). (C) Cartilage regenerative capability of chondrospheroids. Predifferentiated chondrospheroids were transplanted into a human xenografted RA model. Implanted RA-patient derived synovium, cartilage, and bone were explanted 8 weeks after chondrospheroid transplantation. Hematoxylin and eosin staining was performed on sections; typical images are shown (200×; scale bar: 20 μm; arrow: synovial invasion to cartilage). (D–G) Quantification of volume of cartilaginous particles formed in mice treated with (D) MTX, (E) PSL, (F) adalimumab, or (G) tocilizumab. Antirheumatic agents were continuously subcutaneously infused for 30 days in chondrospheroid-engrafted mice. MRI imaging of explanted micromass was acquired to evaluate the volume of chondrospheroids. Results are described as the median and interquartile range (difference between 25 th and 75 th percentiles) (n=5). MSC, mesenchymal stem cell; MTX, methotrexate; PBMCs, peripheral blood mononuclear cells; PSL, prednisolone.
Techniques Used: In Vivo, Drug discovery, Derivative Assay, Expressing, Transplantation Assay, Immunohistochemical staining, Staining, Imaging
