Project description:Purpose:The purpose of this study is to create unbiased, stage-specific transcriptomes by RNA-seq analyses of pure populations of both murine and human erythroblasts at distinct developmental stages. Methods: Recently developed FACS-based methods (Chen et al, PNAS, Liu et al, Blood, Hu et al Blood) were employed to purify morphologically and functionally discrete populations of cells, each representing specific stages of terminal erythroid differentiation. RNA was prepared from these cells and subjected to RNA-seq analyses. Results: There were vast temporal changes in gene expression across the differentiation stages, with each stage exhibiting unique transcriptomes.Clustering and network analyses revealed that differing stage-specific patterns of expression across differentiation were transcriptionally enriched for genes of differing function. Numerous differences were present between human and murine transcriptomes, with significant variation in the global patterns of gene expression. Conclusions: These data provide a significant resource for studies of normal and perturbed erythropoiesis, allowing a deeper understanding of mechanisms of erythroid development, differentiation, and inherited and acquired disease. Both murine and human erythroblasts at distinct developmental stage mRNA profiles were generated by deep sequencing, in triplicate, using IlluminaHiSeq 2000.

Project description:Mammalian erythroid cells development can be divided into three period: hematopoietic stem and progenitor cells (HSPC), erythroid progenitor (Ery-Pro) and erythroid precursor (Ery-Pre). To better understand human erythropoiesis and its regulation, we performed genome-wide studies of chromatin architecture, enhancer and select transcription factors binding, and transcriptomics profiling utilizing modified strategy to obtain defined progenitor and precursor populations from primary human erythroid cells. Integration and analysis of these data reveals that the TAD structure is stable but promoter - enhancer interactions are highly dynamic in a stage specific manner. Erythroid master regulator - GATA1 involves in the P-E interactions stepwisely. GATA1 binding is largely stable in erythroid progenitor and precursor, but dynamic GATA1 binding during this process regulate a productive erythroid gene expression and local chromatin rewiring. Additionally, we also have showed that dosage of GATA1 control the erythroid progenitor behavior and the erythroid progression. The valuable chromatin architecture and epigenome data will provide more comprehensive insight of human erythropoiesis and dynamic gene regulation of cellular differentiation even more broadly.
