[Preparation of low immunogenic porcine dermal scaffold and evaluation of its cytocompatibility].

Objective: To observe the changes in the structure and cytocompatibility of porcine acellular dermal matrix, which was prepared with dermal reticular layer, treated with matrix metalloproteinase 7 (MMP-7), genipin, and vacuum freeze-drying.

Methods: Fifty-four pieces of porcine dermal reticular layer, prepared with lateral abdominal skin were obtained from healthy large Yorkshire pig with mechanical method under sanitary condition, each 10.0 mm×5.
