In vivo wound healing models are predictive preclinical tests for therapeutics that enhance skin repair or limit scarring. Large animals, such as swine, heal in a manner similar to humans, but testing is impractical and expensive. Experiments in mice are more economic, but may be less translatable as this species heals primarily through contraction, not by the processes of epithelialization and granulation tissue formation as seen in human wounds. Here, we describe a murine model of thermal burn injury that closely mimics human healing, resulting in a large, hypertrophic-like scar. This practical, reproducible model is ideal for testing promising wound-healing therapies, such as virus-derived growth factors and immune-modulatory proteins.

Neuroinflammation plays a key role in the development of neurodegenerative diseases, with microglia regulating this process through pro-inflammatory M1 and anti-inflammatory M2 phenotypes. Studies have shown that human umbilical cord mesenchymal stem cells (hUCMSCs) modulate neuroinflammation by secreting anti-inflammatory cytokines. Photobiomodulation (PBM), a non-invasive therapy, has demonstrated significant potential in alleviating neuroinflammation.

Introduction/aims: Duchenne muscular dystrophy (DMD) is caused by pathogenic variants in the DMD gene, making muscle fibers susceptible to contraction-induced membrane damage. Given the potential beneficial action of cannabidiol (CBD), we evaluated the in vitro effect of full-spectrum CBD oil on the viability of dystrophic muscle fibers and the in vivo effect on myopathy of the mdx mouse, a DMD model.
Methods: In vitro, dystrophic cells from the mdx mouse were treated with full-spectrum CBD oil and assessed with cell viability and cytotoxic analyses.

In triple-negative breast cancer (TNBC), pro-tumoral macrophages promote metastasis and suppress the immune response. To target these cells, a previously identified CD206 (mannose receptor)-binding peptide, mUNO was engineered to enhance its affinity and proteolytic stability. The new rationally designed peptide, MACTIDE, includes a trypsin inhibitor loop, from the Sunflower Trypsin Inhibitor-I.

Colorectal cancer (CRC) usually creates an immunosuppressive microenvironment, thereby hindering immunotherapy response. Effective treatment options remain elusive. Using scRNA-seq analysis in a tumor-bearing murine model, it is found that lobeline, an alkaloid from the herbal medicine lobelia, promotes polarization of tumor-associated macrophages (TAMs) toward M1-like TAMs while inhibiting their polarization toward M2-like TAMs.

Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor-site bone harvesting can be associated with post-surgical complications. There has been widespread adoption of exogenously sourced particulate bone graft materials (BGM) for bone regenerative procedures; however, the particulate nature of these materials may lead to compromised healing outcomes, mainly attributed to structural collapse of the BGM, prolonged tissue healing. In this study, a fully synthetic thermoresponsive hydrogel-based universal carrier matrix (TX) that forms flowable and shapable putties with different BGMs while spatially preserving the particles in a 3D scaffold at the implantation site is introduced.
