For tight junctions, rcSF3 and embryonic age primarily affect mRNAs of the claudin family. The ratio of (expression in culture)/(expression in native E14 RPE) is expressed as a natural logarithm. The dashed lines at ±0.7 represent a 2X deviation from expression on E14 in vivo. Complete gene descriptions and values for hybridization to the microarray are included in Appendix 6.
