Following animal euthanasia, samples of all wounds were frozen in RNAlater (Ambion, Austin, TX) at -80oC for molecular analysis. The epithelium of all incisional grid samples was mechanically separated from the underlying mesenchymal tissue using a single-edged razor blade (Schierle et al. 2007), and was homogenized in RLT buffer (Qiagen, Valencia, CA) with 1% beta- mercaptoethanol using a PowerGen Model 500 Homogenizer (Fisher Scientific, Houston, TX). Total RNA was extracted and purified using the RNeasy kit (Qiagen, Valencia, CA) as previously described (Reno et al. 1997). RNA quality was determined using the Agilent Bioanalyzer (Agilent Technologies, Santa Clara, CA).
