MicroRNA expression data from differentiation of human Cyt49 ESCs into definitive endoderm on MEF feeder layers

Pluripotent hESCs can differentiate into the three primary embryonic lineages (endoderm, mesoderm, ectoderm) as well as extraembryonic tissues. Definitive endoderm is the first step into the pathway to endoderm dreived tissues (pancreas, liver, gut, lung) We used microarrays to detail the changes in microRNA expression during the transition from pluripotent hESCs into definitive endoderm hESCs (Cyt49) were differentiated in the presence of Activin A and Wnt3A under low serum conditions to induce DE. formation. Samples were collected at day 0 (hESCs), and day 4 (DE).
