The present study analyzed the tissue reaction to two novel porcine-derived collagen materials: pericardium versus dermis.

Methods:
Tissue reactions were investigated after subcutaneous implantation in mice. Histologic, histochemical, immunohistologic, and histomorphometric analysis methodologies were applied.

Results / Conclusion:
The pericardium-derived membrane induced two different cellular tissue reactions. The compact surface induced mononuclear cells and multinucleated giant cells, and underwent a complete degradation until day 30. The spongy surface of the membrane induced mainly mononuclear cells, and served as a stable barrier membrane for up to 60 days. The present data demonstrate the diversity of the cellular tissue reaction toward collagen-based materials from different tissues.
