MXene enhanced the phosphorylation of PI3K and Akt in skin flaps under ischaemic microenvironment. A Western blotting bands of PI3K, p-PI3K, Akt, and p-Akt proteins. B, C Quantified the ratios of p-PI3K/PI3K and p-Akt/Akt proteins levels among the 5 groups. D, E The necrotic area was imaged on POD 7, and the percentage of the flap's necrotic area was quantified in the graph. F, G The vascular network and corresponding blood flow intensity were quantified using LDBF on POD 7. N = 3 per group. SEM error bars are used. Significance (*): p value < 0.05
