Abstract
A wound, defined as a disruption in the continuity of the skin, is among the most common issues in the population and poses a significant burden on healthcare systems and economies worldwide. Despite the countless medical devices currently available to promote wound repair and skin regeneration, there is a growing demand for new skin devices that incorporate innovative biomaterials and advanced technologies. Bioglasses are biocompatible and bioactive materials capable of interacting with biological tissues. Due to their ability to promote fibroblast proliferation, angiogenesis, collagen production, and evade antibacterial activity, they have been suggested as key players in the skin regeneration process. Since their initial introduction, various compositions have been proposed depending on the clinical goal to be achieved. Recently, a novel bioglass composition named Bio_MS was found to exhibit significant bone regenerative potential. Given its peculiar composition characterized by strontium and magnesium, Bio_MS could also play a role in skin healing. In the present work, an innovative patch was designed by combining the attractive characteristics of Bio_MS with bioprinting technology. The regenerative potential of the Bio_MS patch was tested in an ex vivo cutaneous model using human skin in which an experimental wound was induced by sodium dodecyl sulfate incubation. After injury, the Bio_MS patch was able to restore skin architecture and enhance the epidermal barrier function. Additionally, the Bio_MS patch demonstrated therapeutic effects in both the epidermis and dermis, making it suitable not only for superficial lesions but also for deep wounds.File | Dimensione | Formato | |
