Generation of skin appendages in engineered skin substitutes has been limited by lack of trichogenic potency in cultured postnatal cells. To investigate the feasibility and the limitation of hair regeneration, engineered skin substitutes were prepared with chimeric populations of cultured human keratinocytes from neonatal foreskins and cultured murine dermal papilla cells from adult GFP transge...

Skin wound closure remains a major problem in acute and reconstructive skin grafting after large burns because of limited availability of donor skin. This report evaluates six protocols for preparation in vitro of skin substitutes composed of cultured human cells, biopolymers, and growth factors for wound closure. Full-thickness wounds in athymic mice treated in a single procedure with cultured...

Objective The aim of this study was to obtain autologous dermal-epidermal skin substitutes from oral mucosa from diabetic subjects as a first step towards a possible clinical application for cases of diabetic foot. Material and Methods Oral mucosa was obtained from diabetic and healthy subjects (n=20 per group). Epidermal cells were isolated and cultured using autologous fibrin to develop der...

OBJECTIVE To assess the safety and efficacy of bioengineered skin substitutes in comparison with biological skin replacements and/or standard dressing methods in the management of burns, through a systematic review of the literature. METHODS Literature databases were searched up to April 2006, identifying randomised controlled trials. RESULTS Twenty randomised controlled trials were include...

BACKGROUND Staphylococcal scalded skin syndrome (SSSS) is a rare toxin-mediated skin disease caused by Staphylococcus aureus and seen in infants and children younger than 5 years. OBJECTIVES The supportive role of skin substitutes in SSSS is stressed as a new and relatively unknown method. METHODS Retrospective observational case-series study, in neonates and young infants diagnosed with SS...

Replacing skin defects has witnessed several developments over the centuries. It started with the introduction of skin grafting by Reverdin in 1871. Since then, varieties of skin grafting techniques have been used successfully. Despite being clinically useful, skin grafts have many limitations including the availability of the donor site especially in circumstances of extensive skin loss, immun...

Cultured skin substitutes have become useful as adjunctive treatments for excised, full-thickness burns, but no skin substitutes have the anatomy and physiology of native skin. Hypothetically, deficiencies of structure and function may result, in part, from nutritional deficiencies in culture media. To address this hypothesis, vitamin C was titrated at 0.0, 0.01, 0.1, and 1.0 mM in a cultured s...
