Surface-Coated Polylactide Fiber Meshes as Tissue Engineering Matrices with Enhanced Cell Integration Properties
Figure 11
Local inflammatory reaction measured as tissue section area positively stained in immunohistochemistry by CD163-positive tissue macrophages in the peri-implant tissue and implant-infiltrating tissue following i.m. implantation of untreated electrospun PLA meshes (white columns) or PPAAm-coated meshes (gray columns) after 7, 14, and 56 days in Lewis rats. Columns represent the mean, and error bars represent the standard deviation of 8 rats per experimental day. Hash symbols (#) indicate a significant difference (; ) versus day 7 (Wilcoxon rank-sum test).
