Table displaying relative differences in threshold cycles of genes studied in the RT2 Profiler Array for Human Fibrosis (Qiagen). The gene symbol corresponds to the abbreviation for the gene product. The difference was calculated by subtracting the threshold cycle values for MCAA+ serum treatment from those of the cleared serum treatment. Positive difference values indicate there was more starting mRNA in the MCAA+ samples than the cleared samples, while negative difference values indicate less starting mRNA in the MCAA+ samples than the cleared samples. Gene pathways of either treatment type that never crossed the threshold were omitted.
