Article Title: Mesenchymal stromal cells-loaded 3D radially aligned composite scaffold with potentiated paracrine signaling for sequential bone regeneration

doi: 10.1016/j.bioactmat.2026.02.059

Figure Lengend Snippet: Temporal analysis of the BMSC paracrine profile on different scaffolds. (A) Confocal microscopy images from Live/Dead fluorescence staining of BMSCs encapsulated within the PCL/HAp-GelMA/BMSCs scaffold after 1, 3, 5, and 14 d of 3D culture (live cells, green; dead cells, red). (B) The concentrations of key paracrine factors (TGF-β, PGE2, VEGF, HGF, and BMP-2) from BMSCs cultured in different scaffolds, quantified from culture supernatants at day 3 and day 7. (C) Corresponding relative mRNA expression levels of TGFB1, PTGS2, VEGFA, HGF, and BMP-2 in BMSCs at day 3 and day 7, as determined by qPCR analysis. Data are presented as mean ± SD (n = 3) *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001; ns: not significant.

Article Snippet: ELISA kits for PGE2 (Cat. No. E-EL-0034), TGF-β (Cat. No. E-EL-0162), VEGF (Cat. No. E-EL-R2603), and HGF (Cat. No. E-EL-R0496) were purchased from Elabscience (Wuhan, China).

doi: 10.1039/d6ra00275g

Figure Lengend Snippet: (a) Experimental setup to evaluate the cytotoxicity of individual DL-JPatch components. (b) Comparison of fluorescence images showing human gingival fibroblasts (HGF-1) labeled with Calcein AM (live, green) or Propidium iodide (dead, red) after 24 h of co-culture with hydrogel patches (blank patch, CHI-G/TA, CHI-G/CeO 2 /Gp). (c) Quantification of the relative proportions of live and dead cell populations. ( n = 5–7 per group, ns: no significance, one-way ANOVA test) (d) cell viability measured by absorbance at 450 nm using CCK-8 assay after 24 h of co-culture with hydrogel patches (blank patch, CHI-G/TA, CHI-G/CeO 2 /Gp). ( n = 3, ns: no significance, one-way ANOVA test) (e) Relative body weight changes over 21 days. Red arrows and dotted lines indicate the days of repetitive patch application (days 1, 2, 7, and 14). ( n = 3, ns: no significance, two-way ANOVA test). (f) Representative H&E-stained images of each organs isolated 7 days after final application. All data are means ± s.d.
