November 2013 in “Journal of clinical & experimental dermatology research” This narrative review discusses the potential of urinary bladder matrix as a bio-scaffold in hair restoration but provides no new clinical results or trials; it highlights regenerative technology and suggests further exploration.
August 2025 in “Journal of Polymer Science” This review reports that combining adipose-derived stem cells with decellularized extracellular matrix enhances tissue repair by improving scaffold biological activity and promoting angiogenesis, integration, and functional regeneration across various tissues, while addressing challenges in traditional transplantation methods.
March 2026 in “Journal of Biomedical Materials Research Part B Applied Biomaterials” This study found that a chitosan, chondroitin sulfate, and hyaluronic acid scaffold improved wound healing in rats by promoting immune-stromal interactions, reducing inflammation, and supporting tissue regeneration with ~91% wound closure by day 17 compared to ~63% in controls.
