Genes are listed that show expression ratios ≥2 and that were identified by clustering and significance analysis (compare text and Table S1). Ratios were calculated with the average median intensities of the twelve arrays for A cells (A/P ratio) or P cells (P/A ratio). Ratios were rounded to one decimal place.
