Article Title: Scaffold-mediated miRNA-155 inhibition promotes regenerative macrophage polarisation leading to anti-inflammatory, angiogenic and neurogenic responses for wound healing

doi: 10.1016/j.bioactmat.2026.02.004

Figure Lengend Snippet: Non-polarised (M0) macrophages grown on CG-155-i scaffolds are driven towards an anti-inflammatory (M2) phenotype. A-B) Assessment of cell viability using metabolic activity and DNA content showed increased macrophage activity and proliferation on the CG-155-i group over 7 days. C-E) Gene expression analysis of miRNA-155 and downstream genes demonstrate the activation of anti-inflammatory processes following miRNA-155 inhibition via SHIP1 and SOCS1. F-J) Marker analysis of pro-inflammatory M1 macrophage phenotype (NOS2, CD80, and CD86) and anti-inflammatory M2 phenotype (ARG-1 and CD206) highlight a clear modulation of macrophage polarisation towards an anti-inflammatory state in CG-155-i scaffolds as evidence by decreased NOS2 and CD80 and upregulated ARG1. K-P) Quantification of TNF-α, IL-10, and VEGF expression at post-transcriptional and post-translational levels further evidences the M2 polarisation of macrophages on CG-155-i scaffolds as shown by IL-10 and VEGF upregulation. Data shows mean ± SD (n = 5), ∗ indicates p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001.

doi: 10.1016/j.bioactmat.2026.02.004

Figure Lengend Snippet: Pro-inflammatory (M1) macrophages are driven towards an anti-inflammatory (M2) phenotype on CG-155-i scaffolds. A-B) Assessment of cell viability through metabolic activity and DNA content showed increased macrophage activity and proliferation on the CG-155-i group over 7 days. C-E) Scaffold-mediated inhibition of miRNA-155 in pro-inflammatory macrophages maintains SHIP1 and SOCS1 upregulation despite the enhanced inflammatory environment. F-H) NOS2 expression shows a trending decrease while CD80 and CD86 levels are downregulated on the CG-155-i scaffolds. I-J) Scaffold-mediated miRNA-155 inhibition does not significantly alter ARG1 expression whereas CD206 is still upregulated, highlighted an M2 macrophage polarisation despite the inflammatory cues. K-P) Quantification of TNF-α, IL-10, and VEGF expression at post-transcriptional and post-translational levels further evidences the M2 polarisation of macrophages on CG-155-i scaffolds as shown by IL-10 and VEGF upregulation. Data shows mean ± SD (n = 5), ∗ indicates p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001.

Figure Lengend Snippet: Secretome from macrophages cultured on CG-155-i scaffolds induces anti-inflammatory responses on endothelial cells. A) Cytokine profile analysis revealed an increased release of pro-angiogenic and anti-inflammatory growth factors from macrophages on CG-155-i scaffolds. B-E) Endothelial cells exposed to M0 macrophage secretome show a reduced expression of pro-inflammatory ICAM in the CG-155-i group. F-I) M1 macrophage secretome on endothelial cells elicits clear morphological changes and decreased ICAM intensity in the CG-155-i group. Scale bars = 100 μm.

Figure Lengend Snippet: Secretome from macrophages on CG-155-i scaffolds enhances endothelial cell migration and organisation into vascular-like structures under chronic-like conditions. A) Endothelial cells exposed to M1 macrophage secretome show reduced migration rates compared to M0 conditions. B-C) Analysis of migration profiles under M0 conditions did not reveal any clear differences in behaviour between treatment groups. D-E) Endothelial cell migration rate exposed to secretome from M1 macrophages on CG-155-i scaffolds result in faster cell migration compared to the negative and miRNA-free groups after 24 h. E) Endothelial cells show higher vascular-like organisation when exposed to M0 macrophage secretome. F-H) Secretome from CG-155-i scaffolds enables improved vascular-like complexity in both M0 and M1 conditions. Scale bars = 500 μm.

Figure Lengend Snippet: Comparison of p16, VEGF and PD-L1 in matching tumor tissue. In four cases we found VEGF on DTCs but not in matching tumor tissue, indicating a potential therapeutic target. Further, we detected PD-L1 on DTCs in 11 patients that had PD-L1 negative tissue at diagnosis, suggesting a potential discordance between tumor tissue and DTC phenotype.

Figure Lengend Snippet: Study design. At diagnosis a tissue biopsy was obtained to histologically confirm cervical cancer cases. The FFPE tissue samples were stained against p16, PD-L1 and VEGF for comparison with DTC profiles. One day prior to oncologic surgery, blood samples were collected for CTC detection using the standardized CK based brightfield method. Bone marrow aspirates were sampled during surgery and DTCs were analyzed using the CK based and the multi-parameter IF staining method. Post-operative follow-up blood samples were collected within two years after surgery during routine visits if applicable. Clinical Outcome was assessed up to February 2025.
