23 Jul Method for preparing SIS tissue repair material
Abstract
The invention provides a method for preparing an SIS tissue restoring material. The method comprises the following steps: carrying out sterilizing treatment, degreasing treatment, cell free treatment and absterging treatment according to an arbitrary sequence at the lower layer of small intestinal mucosa; and finally preparing the material through freezing and drying. The SIS tissue restoring material can be used as an independent and common support vector for a growth factor, a cell, a drug and the like, and becomes a tissue engineering material through in-vitro culture. The material is a natural and nontoxic biological material without antigenicity and immunity. The SIS tissue restoring material can be used for restoring hernia, defect of skin, urinary system tissue defect, mucosa defect and other periphery and internal parenchyma defects.
