ABSTRACT: Pluripotent hESCs can differentiate into the three primary embryonic lineages (endoderm, mesoderm, ectoderm) as well as extraembryonic tissues. Definitive endoderm (DE) 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.

We used microarrays to detail the changes in microRNA expression during the transition from pluripotent hESCs into definitive endoderm. hESCs (H9) 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).

Definitive endoderm (DE) is the first step into the pathway to endoderm derived tissues: pancreas, liver, gut, lung. We used microarrays to detail the changes in mRNA expression during the transition from pluripotent hESCs into definitive endoderm.

Project description:Optimizing the efficiency of definitive endoderm differentiation is significant for the generation of diverse organ-like structures. In this study, we utilized saracatinib to enhance definitive endoderm differentiation in pluripotent stem cells. We found saracatinib significantly improved the definitive endoderm differentiation at low concentrations. To investigate the impact of 0.5 μM saracatinib on definitive endoderm differentiation of ESC H1 cells, we conducted RNA-seq analysis with differentiated cells with or without 0.5 μM saracatinib treatment.
Project description:Human pluripotent stem cells (hESCs) are an excellent model to dissect the transcriptional changes that direct cell fate decisions and lineage specification during development. Utilizing directed differentiation protocols to derive definitive endoderm, splanchnic mesoderm, neural progenitor cells (NPCs), and pre-neural crest stem cells (NCSCs) from hESCs. Transcriptional profiling via RNA-seq on hESCs and cells differentiated to all three germ layers revealed lineage specific transcriptional networks that remodeled many cell processes, including epigenetic status, cell surface markers, cell cycle profiles, metabolic flux, and cellular signaling pathways. From this data we were able to verify that metabolic flux within NPCs and pre-NCSCs are regulated in a lineage specific manner that is distinct from endoderm and mesoderm formation.
Project description:Understanding the molecular mechanisms controlling early cell fate decisions in mammals is a major objective towards the development of robust methods for the differentiation of human pluripotent stem cells into clinically relevant cell types. Here, we used human embryonic stem cells (hESCs) to study specification of definitive endoderm in vitro. Using a combination of whole genome expression and ChIP-seq analyses, we established a hierarchy of transcription factors regulating endoderm specification. Importantly, pluripotency factors, namely NANOG, OCT4 and SOX2 have an essential function in this network by actively directing differentiation. Indeed, these transcription factors control the expression of EOMES, which marks the onset of endoderm specification. In turn, EOMES interacts with SMAD2/3 to initiate the transcriptional network governing endoderm formation. Together, these results provide for the first time a comprehensive molecular model connecting the transition from pluripotency to endoderm specification during mammalian development.
