Cell migration requires spatiotemporal integration of signals that regulate cytoskeletal dynamics. In response to a migration-promoting agent, cells begin to polarise and extend protrusions in the direction of migration. These cytoskeletal rearrangements are orchestrated by a variety of proteins, including focal adhesion kinase (FAK) and the Rho family of(More)
BACKGROUND Transplantation of skin micrografts (MGs), split-thickness skin grafts (STSGs), or cultured autologous keratinocytes (CKs) enhances the healing of large full-thickness wounds. This study compares these methods in a porcine wound model, investigating the utility of micrograft transplantation in skin restoration. STUDY DESIGN Full-thickness(More)
Transplantation of skin micrografts in a 1:100 ratio regenerate the epidermis of full-thickness wounds in pigs within 14 days in a wet environment. The aim of the current study was to combine micrografts and commercially available moist dressings. We hypothesized that micrografts regenerate the epidermis when covered with a moist dressing. 5cm×5cm and(More)
Chronic hepatitis C is a leading cause of end-stage liver disease and, with a worldwide prevalence of up to 3%, is a pandemic infectious disease. Austria, like most western European countries can be considered as a low prevalence country. This analysis aimed to assess the distribution of hepatitis C virus (HCV) genotypes in patients with chronic HCV(More)
OBJECTIVE Tendon injuries produce considerable morbidity, long-lasting disability, and remain a considerable challenge for clinicians and patients. The objective of the study was to assess the effect of amnion-derived multipotent progenitor (AMP) cells and amnion-derived cell cytokine solution on Achilles tendon healing by using a rat model. METHODS(More)
The process of wound healing is dynamic and takes place over months to years, during which there is a resolution of angiogenesis, continued wound contraction, and connective tissue remodeling. The outcome of this process is most commonly the formation of a scar, defined as a fibrous tissue replacing normal tissues destroyed by injury or disease. Scars often(More)
ABSTRACT Decreased inflammatory response seen in wet wound healing may be correlated with diminished scarring. This study seeks to test this hypothesis and to validate a model of scarring in the Yorkshire pig. Four Yorkshire pigs were used to create 36 dorsal wounds per pig (144 wounds total) in the following groups: full-thickness excisional, partial(More)
BACKGROUND Injury to the skin can predispose individuals to invasive infection. The standard of care for infected wounds is treatment with intravenous antibiotics. However, antibiotics delivered intravenously may have poor tissue penetration and be dose limited by systemic side effects. Topical delivery of antibiotics reduces systemic complications and(More)
BACKGROUND Major loss of skin following burns or trauma requires skin grafting for repair. In addition, chronic wounds frequently require skin grafts. Current treatments are either cumbersome, limited in possible expansion ratio, costly, or require extensive time for treatment. This study investigates a new way of regenerating skin after major burns and(More)
OBJECTIVE In the United States, around 50% of all musculoskeletal injuries are soft tissue injuries including ligaments and tendons. The objective of this study is to assess the role of amnion-derived cellular cytokine solution (ACCS) in carboxy-methyl cellulose (CMC) gel in the healing of Achilles tendon in a rat model, and to examine its effects on(More)
