Characterization of an Acellular Dermal Matrix Obtained by Different Detergent-Enzymatic Methods

Acellular dermal matrixes (ADM) for reconstructive surgery were made by treating skin samples from rats and humans with sodium dodecylsulfate (SDS), sodium deoxycholate (DOC), saponin, and DNase. A mixture of SDS and DOC removed cell residues effectively, though the ADM had cytotoxic properties. After treatment with 2% DOC, there was no cytotoxic effect and the resulting material contained 27-202 ng/mg dry weight DNA and from 0.07 to 2.6% fat, depending on the source of the samples.
