We have used a dual transgenic color reproter system to isolate purified populations of these progenitors. We used microarrays to detail the global programme of gene expression underlying cardiac development in mouse; All four populations of cells are derived from embryonic stem cells differentiating in vitro (day 6 of in vitro differentaition). The stem cell line has two transgenic reporters as follows:; 1. The second heart field (SHF) specific reporter of the Mef2C gene (E. Dodou, S. M. Xu, B. L. Black, Mech Dev 120, 1021 (Sep, 2003)) driving the expression of dsRed; 2. The cardiac specific enhancer ( C. L. Lien et al., Development 126, 75 (Jan, 1999)) driving the expression of eGFP. Thus, the red cells are SHF specific, the green cells are cardiac specific, and the red/green are SHF and cardiac specific. These cells are compared to the double negative cells which serve as a control. Experiment Overall Design: Embryonic stem cell derived progenitors were isolated into four distinct populations by FACS purifying these progenitors based on a two color reporter system. Four populations were then compared to each other by transcriptional profiling.E-GEOD-17513http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-17513/samples/
