|a Stem cell-based therapies have exhibited significant promise in the treatment of diabetic ulcers (DU). Nevertheless, enhancing the survival rate and functionality of transplanted stem cells poses a substantial challenge. In this study, inspired by the breadmaking process, yeast microcarriers (YMC) are devised as vehicles for stem cells to address these challenges. The fabrication of YMC involves the amalgamation of microfluidic emulsification with yeast-mediated fermentation, yielding microcarriers with outstanding biocompatibility, high porosity, and antioxidant activity. Adipose-derived stem cells (ADSCs) seeded onto YMC display remarkable cell viability and retain their cellular functions effectively. Additionally, YMC boast a rich glutathione content and exhibit remarkable ROS scavenging ability, thus shielding the ADSCs from oxidative stress. In vivo experiments further substantiate that ADSCYMC implementation significantly lowered ROS levels in diabetic wounds, resulting in enhanced stem cell retention and improved angiogenesis, collagen deposition, and tissue regeneration. These results highlight the potential of ADSC@YMC as a promising platform for delivering stem cell in the treatment of diabetic wounds
