Treatment of a non-healing oral wound in diabetic-induced rats

Aim: Non-healing wounds are one of the most substantial and difficult problems to treat. Wound healing involves a sequence of complex biological processes, but often the oral cavity microbiota adversely affects healing and forms a chronic non-healing wound. Methods: In this study, a biologically active membrane (BAM) is present, consisting of decellularized human amniotic membrane and bone marrow stem cells (BMSCs). The efficacy of BAM was evaluated in a model of non-healing oral wounds in rats with streptozotocin (STZ)-induced diabetes mellitus. Results: Studies have shown that BAM enhanced the healing of chronic oral wounds in animals with induced diabetes mellitus, reduced scarring, and reduced risk of infection. Paracrine freeze-dried BMSCs stimulated angiogenesis and improved wound conditions. Conclusions: BMSCs may lower glucose levels in rats with STZ-induced diabetes mellitus and improve the healing process of chronic diseases. However, more studies are needed to study the paracrine factors of BMSCs and their role in the treatment of non-healing wounds.
