In vivo molecular imaging of murine embryonic stem cells delivered to a burn wound surface via Integra® scaffolding.

It has been demonstrated that restoration of function to compromised tissue can be accomplished by transplantation of bone marrow stem cells and/or embryonic stem cells (ESCs). One limitation to this approach has been the lack of noninvasive techniques to longitudinally monitor stem cell attachment and proliferation. Recently, murine ESC lines that express green fluorescent protein (GFP), luciferase (LV), and herpes simplex thymidine kinase (HVTK) were developed for detection of actively growing cells in vivo by imaging.

Simvastatin treatment improves survival in a murine model of burn sepsis: Role of interleukin 6.

Infection is the most common and most serious complication of a major burn related to burn size. Recent studies have demonstrated that statin treatment can decrease mortality in murine or human sepsis. In the current study mice were anesthetized and subjected to a dorsal 30% TBSA scald burn.

Effect of insulin levels on the phosphorylation of specific amino acid residues in IRS-1: implications for burn-induced insulin resistance.

Alterations in the phosphorylation and/or degradation of insulin receptor substrate-1 (IRS-1) produced by burn injury may be responsible, at least in part, for burn-induced insulin resistance. In particular, following burn injury, reductions in glucose uptake by skeletal muscle may be secondary to altered abundance and/or phosphorylation of IRS-1. In this study, we performed in vitro experiments with 293 cells transfected with IRS-1.
