Morphology of fibroblasts was studied around the scaffolds right after 7 days of culturing. SEM pictures indicated fibroblast cells formed typical spindle-shaped cells on all scaffolds (Fig 3A, B). As shown H E pictures of scaffold with no cell (Fig 3C, D) and fibroblast cells were able to penetrate, attach and grow in to the 3D structures of 3D spongy AM scaffold (Fig 3E, F) because of the presence of large pores. Cell metabolic activities in scaffolds Cell metabolic activity of fetal fibroblast cells in 3D spongy AM scaffolds had been evaluated at each and every indicated time interval primarily based MTS assay (Fig 3G).The results of metabolic activity of human fetal fibroblast cells in 3D spongy AM scaffolds showed an rising trend over 7, 14, and 21 days, but no significant variations had been observed in the course of three and 7 days of incubation.CELL JOURNAL(Yakhteh), Vol 16, No 4, WinterFabrication of Spongy Denude AM ScaffoldABCDEFGFig 2: 3D AM scaffold working with Russell- Movat staining (collagen, yellow) and (GAG, Green) (A).

HAM is an appropriate substitute for basic skin for surgical use on account of its availability, low price, and low danger of viral illness transmission and immunologic.
