Aims:
Superficial burns and scalds are usually managed conservatively with traditional dressings. Failure to heal within 3 weeks leads to their management by skin grafting. Our aim was to develop a biomaterial to actively promote keratinocyte migration in superficial burns by modulating local cation concentrations to accelerate keratinocyte migration and deter wounds from contracting, thus potentially reducing the number of such wounds requiring grafting.
Materials & Methods:
We investigated polymeric hydrogels for their Ca(2+) chelating properties and enhancement of keratinocyte migration in human tissue-engineered skin models.
Results:
Dimethylaminoethyl methacrylate:methacrylic acid hydrogel coupled with elevated [Mg(2+)] reduced media [Ca(2+)], potentiating keratinocyte migration in tissue-engineered skin models, it also significantly reduced wound model contraction.
Conclusion:
Dimethylaminoethyl methacrylate:methacrylic acid hydrogels could promote wound healing and reduce wound contraction, a significant complication in burn wound healing.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
