Objective To build artificial dermis by using the acellular dermis matrix(ADM), collagen membrane and collagen gel as scaffolds. Methods The fibroblasts were isolated by enzyme from infant skin and were cultivated in the DMEM medium. After 14 days when the fibroblasts were seeded into 3 different scaffolds, the autografts were detected by HE staining, transmission electron microscope and scanning electron microscope. Results ①The fibroblasts obtained from the fullskin by enzyme could be passaged in the Dulbecco’s modified Eagle’s medium 2high gluco se w ith 10% calf bovine serum. ②A layer of fibroblastsw ere found on the surface of th ree different scaffo lds, the fibroblasts could grow into the co llagen membrane and the co llagengel, but could no t be found in the inner of ADM. ③A rt ificial derm is cont racted slightly by inoculat ing fabricat ion on collagen membrane and ADM , and the fibroblasts on them w ere no t act ive in proliferat ing; but the art ificial derm is built by the collagen gel cont racted obviously. Conclus ion　The art ificial dermis built by ADM , collagen membrane and collagen gel as scaffolds have a preferable structure for an ideal subst itute of sk n, and can beused as the graft in the next experiments.
