Whole-Genome Transcriptome Profiling of Microvascular Free Flaps

In our study, we developed a venous obstruction rat model in which the superficial inferior epigastric (SIE) vessels to the lower abdominal flaps was separated and artery or vein was ligated, and the flap reattached. Flaps were harvested 4 hours post-op. Total RNA was isolated and gene expression profiles were compared by Affymetrix Whole Genome 230 2.0.
