In the field of large-area trauma flap transplantation, preventing avascular necrosis remains a critical challenge. Key mechanisms for improving viability include angiogenesis promotion, oxidative stress inhibition, and cell death prevention. Recently, two-dimensional ultrathin Ti3C2TX (MXene) nanosheets have gained attention their potential contributions to these processes, though MXene's physiological impact on survival had not been previously investigated. This study is first confirm biological effects ischaemic microenvironment post-skin transplantation. Findings indicated that MXene significantly decreased necrotic area in flaps (37.96% ± 2.00%), with reductions 30.40% 1.86% at 1 mg/mL 20.19% 2.11% 2 concentration-dependent manner. Mechanistically, facilitated situ angiogenesis, mitigated stress, suppressed pro-inflammatory pyroptosis, activated PI3K-Akt pathway, particularly influencing vascular endothelial cells. Comparative transcriptome analysis skin tissues without treatment provided additional evidence, highlighting such as ROS metabolic proliferation regulation, signaling pathway activation. Overall, demonstrated activity, effectively promoting presenting novel strategy addressing flaps.
