Figure 8.

Macrophage polarization state after three weeks of in vivo implantation. Immunofluorescence staining of macrophages in the proximity to nonporous and porous P(l)LCL or P(l,d)LCL scaffolds prepared from 7% and 5% polymer gels. Macrophages were stained for F4/80 (red) and mannose receptor (CD‐206, blue, M2) or iNOS (green, M1). The entire section was also stained for DAPI (nucleus, yellow) to identify other cells. Scale bar in all images is 1 mm. Dashed line boxes indicate areas where a zoom‐in was taken. Scale bar in zoom‐in images is 30 µm.
