[Scaffolds based on collagen and chitosan for post-burn tissue engineering].

Unlabelled: Porous scaffolds based on collagen and chitosan have been obtained from mixed bio-polymeric solutions and mixture freeze-drying method in the purpose of using them as materials for post-burns tissue regeneration.

Material And Method: Soluble collagen from bovine leather was obtained by acid-base extraction (isoelectric pH = 4.82).
