Project description:Multilineage differentiation of human embryonic stem cells into three-dimensional (3-D) model, termed as progressed elongated embryoid bodies (peEBs), recapitulates crucial features of early human development, including cardio myogenesis and haematopoiesis. Characterisation of peEBs at transcriptome and protein levels at different stages of development to study embryonic haematopoiesis and endothelial-to-hematopoietic-transition (EHT) in vitro.
Project description:Small RNAs including microRNAs play a critical role at different stages of haematopoiesis. The study was designed to profile miRNA expression during human erythropoiesis.
Project description:Ikaros DNA binding proteins are important regulators of haematopoiesis and genetic deletion of Ikaros results in severe developmental disturbances, including delayed thymocyte differentiation and an early and complete block in B cell development. Although Ikaros ChIP-seq data are available for mouse thymocytes and human haematopoietic progenitors, it has not been achieved in B cell progenitors. The goal of this study was to identify Ikaros binding sites in pre-B cells to define Ikaros target genes which could explain the essential role of Ikaros proteins in B cell differentiation. We carried out chromatin immunoprecipitation and high throughput sequencing (ChIP-seq) with antibodies to the C-terminus of endogenous Ikaros in primary pre-B cells isolated from mouse fetal livers.
