Project description:In this study, we characterised transcriptomes of mESC in different conditions EPSCM and KOSR subsetting them for their single expression of SOX2 or the double expression of SOX2 and GATA6 in these conditions. 2iLIF (sorted only by DAPI negative cells) were used as control.
Project description:The purpose of the study was to identify transcriptomic changes between feeder-free ES and XEN cells. ES cells were cultured feeder-free on 0.1% gelatin in 2iLIF in N2B27 media. XEN cells were also cultured feeder-free on 0.1% gelaton in RPMI1640 supplemented with 15% FBS, 2mM GlutaMAX and BME.
Project description:We recently developed a novel chemical media formulation, Expanded Potential Stem Cell Medium (EPSCM), that maintains mouse pluripotent stem cells (PSCs) in a unique cellular state that affords extraembryonic differentiation capacity. Here, we have used EPSCM to stably maintain human PSCs and used EPSCM-maintained iPSCs (EC-EPSCM) to study in vitro hematopoietic differentiation by embryoid body (EB) formation. We found that human PSCs maintained in EPSCM can spontaneously form embryoid bodies and efficiently undergo in vitro hematopoiesis using a simple differentiation protocol. EC-EPSCM PSCs generated primitive-wave and definitive-wave hematopoietic cells, which were chracterized by RNA-sequencing analysis.
Project description:Assess chromatin accessibility in WT and mutant ES E14 strains using ATAC-seq. Mutant strains are depleted for subunits of the coactivator complexes SAGA (Supt7l KO) or ATAC (Yeats2, Zzz3) using constitutive knock-out (KO) or the auxin-inducible degron (AID) system.
