Expression data from differentiating Flk1- and Flk1+ ES cells expressing Snail during Wnt inhibition. Mus musculus

ES cells differentiated in the presence of the Wnt inhibitor DKK1 fail to express the transcription factor Snail and undergo EMT or mesoderm differentiation. We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of Flk1- and Flk1+ cells generated one day after Snail was expressed during Wnt inhibition. Overall design: A2.snail ES cells, which express Snail upon addition of doxycycline, were differentiated as embryoid bodies in differentiation media and DKK1. Snail-induced cultures uniquely develop a select population of Flk1+ cells. Total RNA was harvested from sorted control (no doxycycline) Flk1- cells and sorted Snail-induced (doxycycline at day 2) Flk1- and Flk1+ cells at day 3 of differentiation.
