Heatmap of SAGE tag counts for genes with known expression profiles in pancreas development. Tags for genes with well characterized expression profiles in pancreas development were identified and their normalized counts obtained in each of the ten SAGE libraries created. A heatmap, generated using the multi-experiment viewer as described in the Materials and methods, of these results is shown based on the counts of the tags per hundred thousand (TPH). SAGE tags used include: TACACGTTCTGACAACT (Nkx2-2); AAGTGGAAAAAAGAGGA (Pdx1); TAGTTTTAACAGAAAAC (Foxa2); ACCTTCACACCAAACAT (Hnf4a); AATGCAGAGGAGGACTC (Neurod1); CAGGGTTTCTGAGCTTC (Neurog3); TCATTTGACTTTTTTTT (Isl1); GATTTAAGAGTTTTATC (Pax6); CAGCAGGACGGACTCAG (Pax4); CAGTCCATCAACGACGC (Ptf1a); AGAAACAGCAGGGCCTG (Bhlhb8); GACCACACTGTCAAACA (Cpa1); CCCTGGGTTCAGGAGAT (Ctrb1); TTGCGCTTCCTGGTGTT (Ela1); ACCACCTGGTAACCGTA (Gcg); GCCGGGCCCTGGGGAAG (Ghrl); CTAAGAATTGCTTTAAA (Iapp); GCCCTGTTGGTGCACTT (Ins1); TCCCGCCGTGAAGTGGA (Ins2). The libraries shown include: Pdx1 EGFP+ TS17 (P+ TS17); Pdx1 EGFP+ TS19 (P+ TS19); Neurog3 EGFP- TS20 (N- TS20); Neurog3 EGFP+ TS20 (N+ TS20); Neurog3 EGFP+ TS21 (N+ TS21); Neurog3 EGFP+ TS22 (N+ TS22); whole pancreas TS22 (WTS22); whole pancreas TS26 (WTS26); adult isolated ducts (Ducts); adult isolated islets (Islets).
