ABSTRACT
A variety of skin substitutes are used in the treatment of full-thickness burns. Substitutes made from skin can harbor
latent viruses, and artificial skin grafts can heal with extensive scarring, failing to regenerate structures such as glands,
nerves, and hair follicles. Biodegradable and patible hydrogels, however, rarely mimic the strength of the epi-
dermis. Therefore, novel and practical skin scaffold materials remain to be developed. harides form hydrogels
with predicted inherent patibility. This paper describes the preparation and patibility of unique hydrogel
skin scaffolds from plant-extracted haride mixtures of specific sources, types, and molecular weight fractions.
These hydrogels have a range of mechanical and degradation properties with the potential to fulfill the multiple, di-
verse functions of artificial skin, including protection, compatibility with different cell types, biodegradation, and re-
lease of needed signals for cell growth and wound healing.
