INS and type 2 diabetes mellitus: Compared with that of the T2DM group, the insulin-positive areas of the M-Cili-F and M-Cili-R groups significantly recovered (5.07 ± 1.92 vs. 0.58 ± 0.34, p = 0.0061; 5.53 ± 1.52 vs. 0.58 ± 0.34, p = 0.0024), which suggested that the expression level of Insulin was restored to a certain extent (Figures 4D,F).
