Figure 7From: Transcriptional profiling of putative human epithelial stem cellsNF-κB activity in α6+/MHCI negative and MHCI positive cells. Nuclear extracts of sorted cells were analyzed for NF-κB p50-binding activity; data were expressed in optical density (O.D.) units obtained with the TransAM ELISA NF-κB assay for phosopho-p50 (**P < 0.017).Back to article page
