Relative mRNA expression of pancreas development transcription factors by CD133+ cells isolated after 4 days of exocrine tissue culture.

Mean ± SEM relative expression level of genes in CD133+ cells compared to the CD133-depleted (CD133D) population shown on Y-axis as fold difference. Significance determined by Student’s t-test from 2^-Δct values. ***, p<0.001, **, p<0.01, *, p<0.05 (n = 4 exocrine cultures). Genes ranked in order of overexpression in the CD133+ population. Inset shows gene expression using an enlarged scale. Genes are: Neurogenin 3 (NGN3), One cut homeobox 2 (ONECUT2), NK6 homeobox 1 (NKX6.1), GLIS family zinc finger 3 (GLIS3), motor neuron and pancreas homeobox 1 (MNX1), HNF1 homeobox B (HNF1B), pancreatic and duodenal homeobox 1 (PDX1), SRY (sex determining region Y)-box 9 (SOX9), Hairy enhancer of split 1 (HES1), One cut homeobox 1 (ONECUT1), Forkhead box A2 (FOXA2), Forkhead box O1 (FOXO1), v-maf avian musculoaponeurotic fibrosarcoma oncogene family, protein B (MAFB), GATA binding protein 4 (GATA4), Pancreas specific transcription factor 1A (PTF1A), Neuronal differentiation 1 (NEUROD1), ISL LIM homeobox 1 (ISL1), paired box 6 (PAX6). No expression of NK2 homeobox 2 or paired box 4 was detected.
