Results of microarray analysis of endodermal organs. (A) Graph of microarray expression values of five genes reported to be specific to endodermal organ domains. Arbitrary expression values are normalized to the average expression among the six organ domains profiled and are displayed on a log scale with standard deviation of three replicates. (B–D) Flow cytometric analysis of live, dissected (B) E11.5 stomach (left) and intestine (right) stained with Dpp4 (X-axis), (C) E11.5 stomach (left), pancreas (middle) and liver (right) stained with Dlk1 (X-axis), and (D) E11.5 stomach (left) and pancreas (right) stained with Rae1 (X-axis), all plotted against pan-endodermal Cdcp1 (Y-axis). The percentage of cells within each quadrant is displayed.
