Title:
ACELLULAR DERMAL TISSUE PREPARED USING SUPERCRITICAL FLUID EXTRACTION, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/195633
Kind Code:
A1
Abstract:
The present invention relates to decellularized acellular dermal tissue prepared using supercritical fluid extraction. More specifically, the present invention relates to an acellular dermal tissue having an improved level of extracellular matrix preservation and optimized mechanical properties such as critical load and elastic restoring force by using supercritical fluid extraction. The acellular dermal tissue according to the present invention is obtained through decellularization without a surfactant treatment so that mechanical properties are maintained, does not possess toxicity resulting from residual surfactants and minimizes transplant rejection, and thus can be effectively used for treatment of patients with damaged skin tissue.
