Figure 10

Morphologies of and macrophage responses to subcutaneously implanted silk fibroin scaffolds in Lewis rats at 6 months (A and B) and 12 months (C and D). Image A is for aqueous-derived scaffold with 850–1000 µm pore size prepared from 10% silk fibroin solution. Image B is for HFIP-derived scaffold with 500–600 µm pore size prepared from 6% silk fibroin solution. Images C and D are for aqueous-derived scaffold with 500–600 µm pore size prepared from 6% silk fibroin solution and with 850–1000 µm pore size prepared from 10% silk fibroin solution, respectively. Bars in A and B = 100 µm and in C and D = 300 µm. Solid arrows = remaining scaffolds. Blank arrows = ED1 positive cells.
