Article Title: 3D-bioprinted, phototunable hydrogel models for studying adventitial fibroblast activation in pulmonary arterial hypertension

doi: 10.1101/2022.11.11.516188

Figure Lengend Snippet: Fibroblast activation in 3D-bioprinted models of pulmonary arterial adventitia. A) Fibrotic activation in soft and stiffened 3D hydrogels measured by αSMA expression. HPAAFs in stiffened constructs were significantly more positive for αSMA than cells in soft constructs. Columns represent mean ± SEM, n = 3. *, p < 0.05, Mann-Whitney U test. B) Representative confocal images of immunostaining for αSMA, actin, and DAPI in soft and stiffened 3D hydrogels. HPAAFs in stiffened constructs showed more prevalent αSMA immunofluorescence than cells in soft constructs. Scale bar = 250 µm. C) Fibroblast proliferation in soft and stiffened 3D bioprinted constructs measured by EdU positivity. HPAAFs in stiffened constructs were significantly more positive for EdU than cells in soft constructs. Columns represent mean ± SEM, n = 3. *, p < 0.05, Mann-Whitney U test. D) Representative confocal images of immunostaining for EdU and Hoechst dye in soft and stiffened 3D hydrogels. HPAAFs in stiffened constructs showed more prevalent EdU immunofluorescence than cells in soft constructs. Scale bar = 300 µm.

Article Title: A novel multikinase inhibitor SKLB‐YTH‐60 ameliorates inflammation and fibrosis in bleomycin‐induced lung fibrosis mouse models

doi: 10.1111/cpr.13081

Figure Lengend Snippet: YTH‐60 inhibits fibroblast activation and proliferation. A‐C, NIH‐3T3, HPF and MRC‐5 were treated with different concentrations of YTH‐60 and Nintedanib for 24, 48 or 72 h and cell viability was measured by the CCK8 assay. The values are expressed as the mean ± SD (n = 3); * P < .05; ** P < .01; *** P < .001 compared with YTH‐60 control; # P < .05; ## P < .01; ### P < 0.001 compared with Nintedanib control. D‐F, Real‐time qPCR analysis of collagen Ⅰ, α‐SMA and TGF‐β1 in NIH‐3T3 cells treated with 5 ng·mL −1 TGF‐β1 and 2.5 μmol·L −1 YTH‐60 or Nintedanib for 24 h. The values are expressed as the mean ± SD, n = 3; * P < .05; ** P < .01; *** P < .001. G‐I, NIH‐3T3, HPF and MRC‐5 were stimulated with TGF‐β1 by 2.5 and 5 μmol·L −1 YTH‐60 administration for 24 h, and expression of α‐SMA and collagen Ⅰ using western blot. J‐K, expression of α‐SMA and collagen Ⅰ was visualized by immunofluorescence, Scale bar = 50 μm
