Abstract
A method for manufacturing an animal acellular tissue matrix material and a tissue matrix material manufactured by the same. The tissue matrix material manufactured by the method retains an original basic scaffold structure of a tissue extracellular matrix, with an antigen causing immunological rejection in a human body being effectively removed from the animal tissue. An animal dermal matrix manufactured by the method retains the biological integrity of a natural dermal tissue matrix and can be used for restoration and repair of lesion and missing tissues.
