Fig. 3.

The swelling, degradation, and delivery of DAM hydrogel (A). The swelling test of DAM hydrogel. (B). The compressive test of DAM hydrogel and aortic peripheral adipose tissue, ∗p < 0.05 Vs. AT. AT: aortic peripheral adipose tissue. (C). The degradation of DAM hydrogel in collagenase solution. (D). The degradation of DAM hydrogel in PBS. (E). The distribution of antagomiR-150-5p in DAM hydrogel, scale bar, 100 μm. (F). The release of antagomiR-150-5p in DAM hydrogel, n = 3. AT: adipose tissue, DAM: decellularized adipose matrix. (G). The length (G1), inner diameter (G2), and the incision (G3) of the silicone hose mold. The silicone hose mold wrapping the abdominal aorta. (H). Images of abdominal aorta (H1). Images of DAM hydrogel delivery on the surface of abdominal aorta (H2) or with silicone hose mold around the abdominal aorta (H3). The yellow dotted lines showed the gel location. (I). The degradation of DAM hydrogel. The distribution of DAM hydrogel is shown at 0, 1, 3, 5, 7 days in the upper panel, the green circle indicated the DAM hydrogel. In the lower panel, Masson's staining showed the DAM hydrogel (Green arrow) around the abdominal aorta at 0, 1, 3, 5, 7 days.
