Figure 1.
Macroscopic pathology and the scheme of experimental design. Representative photos of the macroscopic pathology of subcutaneous tissues in diabetic mice at 6 weeks after pretreatment in the GHNF (A) and control (B) groups are shown. The capsule surrounding the silicon spacer in the GHNF group appeared to be thicker than that in the control group (black arrows). No bleeding or inflammation were observed in either group. The scheme of experimental design (C).
