Application of Acellular Tissue Matrix for Enhancement of Weak Abdominal Wall in Animal Model

Figure 5

Histology evaluation by H&E staining of tissues surrounding implantation materials from representative animals after 12 weeks (at 100x original magnification). The polypropylene group (a) showed an inflammatory reaction around implanted mesh with lymphocytes and plasmocytes more than 50/HPF. The ACTM group (b) showed improved biological degradation, no rejection reaction with lymphocytes and plasmocytes less than 25/HPF, and granulation tissue fibrosis inside.
