[Effects of microporous porcine acellular dermal matrix combined with bone marrow mesenchymal cells of rats on the regeneration of cutaneous appendages cells in nude mice].

Objective: To observe the effects of microporous porcine acellular dermal matrix (ADM) combined with bone marrow mesenchymal cells (BMMCs) population containing bone mesenchymal stem cells (BMSCs) of rats on the regeneration of cutaneous appendages cells in nude mice.

Methods: Split-thickness dermal grafts, 20 cm×10 cm in size and 0.3 mm in thickness, were prepared from a healthy pig which was sacrificed under sanitary condition.
