Article Title: Polygonatum sibiricum polysaccharide alleviates liver fibrosis through the TGF-β/Smad signaling pathway and reduces collagen

doi: 10.3892/mmr.2025.13599

Figure Lengend Snippet: PSP inhibits hepatic collagen production in liver fibrosis-induced rats. Detection of the liver fibrosis markers (A) HA, (B) LN, (C) PIIINP and (D) Col IV in serum samples was performed by ELISA. (E) Expression levels of Col I and Col III in the liver were detected by immunohistochemistry; scale bar, 20 µm. Semi-quantification of (F) Col I and (G) Col III. ELISA was used to detect the levels of (H) Col I and (I) Col III in liver tissue. (J) Levels of Hyp in the liver tissues were detected by ELISA. Data are presented as the mean ± standard deviation, n=6. ### P<0.001 vs. the control group; *P<0.05, **P<0.01 and ***P<0.001 vs. the model group. BJRG, Biejia ruangan; Col, collagen; H, high; HA, hyaluronic acid; Hyp, hydroxyproline; L, low; LN, laminin; PIIINP, procollagen III N-terminal peptide; PSP, Polygonatum sibiricum polysaccharide.

Article Title: Aligned nanofiber scaffolds combined with cyclic stretch facilitate mesenchymal stem cell differentiation for ligament engineering

doi: 10.4252/wjsc.v17.i8.107124

Figure Lengend Snippet: Effects of static and tensile conditions on bone marrow-derived mesenchymal stem cell alignment and tenogenic differentiation on aligned and random nanofiber scaffolds. A: Schematic showing the experimental setup for culturing bone marrow-derived mesenchymal stem cells (BMSCs) on aligned and random nanofiber scaffolds under static and tensile strain conditions; B: Immunofluorescent staining of F-actin (red) and nuclei (4’,6-diamidino-2-phenylindole, blue) illustrating cytoskeletal alignment of BMSCs in response to static and tensile conditions. Under tensile strain, BMSCs on both scaffold types align along the direction of strain (yellow arrows). Scale bars: 50 μm; C: Gene expression levels of tenogenic markers collagen type I alpha 2, collagen type III alpha 1, tenascin C, and tenomodulin in BMSCs on aligned and random scaffolds under static and tensile conditions, showing upregulation of these markers with tensile strain; D: Western blot analysis of tenogenic proteins (collagen I, collagen III, tenascin C, and tenomodulin) in BMSCs cultured on aligned and random scaffolds under static and tensile conditions, with β-actin as the loading control; E: Quantified protein expression levels from western blot, demonstrating scaffold orientation and mechanical strain effects on tenogenic protein expression. a P < 0.05, b P < 0.01. DAPI: 4’,6-diamidino-2-phenylindole; Col1a2: Collagen type I alpha 2; Col3a1: Collagen type III alpha 1.
