Impeding Glial Scarring Hyperplasia and Activating Axon Neogenesis via Immunomodulatory Microneedle Patch for Spinal Cord Repair

This study found that a microneedle patch integrating curcumin-loaded vesicles and a stem cell-derived matrix showed promise in reducing hypertrophic scars and promoting hair follicle formation in a rabbit model.

This study tested a hydrogel microneedle patch delivering T reg attractants in mice with alopecia, finding it boosted regulatory T cell numbers at the site, leading to hair regrowth without causing peripheral immunosuppression, suggesting a potential new approach for autoimmune skin disease treatment.

This study tested a microneedle patch on rabbit and pig models to support skin regeneration, revealing that the treatment accelerated wound closure, reduced scar formation, and promoted hair-bearing tissue and follicle growth, suggesting a trauma-guided framework for skin restoration.

This study found that a newly created biomimetic microneedle platform effectively expedited wound repair in diabetic animal models by reducing inflammation, enhancing angiogenesis, and promoting skin regeneration through targeted drug delivery and immune response modification.

This study found that macrophages treated with keratin in vitro were more similar to anti-inflammatory M2 macrophages and reduced astrocyte reactivity, potentially limiting secondary inflammatory damage after spinal cord injury.
