Figure 8.

Hematoxylin and eosin (H&E) -stained histological sections of the tissue adjacent to the sites of subcutaneous injection of 100 μl of 20% (wt/v) EPSHU into BALB/cJ mice. The EPSHU degraded gradually. Cavities with cell infiltrates had formed inside the gel at Day 3 (A and D), Day 14 (B and E) and Day 28 (C and F) after injection. (A–C) Low magnification of images (40×, scale bar = 500 μm). The rectangular frames indicate the fields chosen for capture at higher magnifications (D–F, 200×, scale bar = 100 μm).
