Cannibalized Erythroblasts Accelerate Developmental Neurogenesis by Regulating Mitochondrial Dynamics

Project description:In this study, we disclose a mechanism triggered during neurulation that programs brain development by donation of sacrificial yolk sac erythroblasts to neuroepithelial cells. At embryonic day (E) 8.5, neuroepithelial cells transiently integrate with the endothelium of yolk sac blood vessels and cannibalize intravascular erythroblasts as transient heme-rich endosymbionts. This cannibalistic behavior instructs precocious neuronal differentiation of neuroepithelial cells in the proximity of blood vessels. By experiments in vitro, we show that access to erythroblastic heme accelerates the pace of neurogenesis by induction of a truncated neurogenic differentiation program from a poised state.

Transcriptional alterations in mDia1-miR146a double deficient erythroblasts and IL-6 treated erythroblasts

Project description:Transcriptome analysis of total RNA samples from FACS sorted erythroblasts To further verify the role of cytokine triggered inflammation signaling in erythropoiesis, we decided to follow the profile of gene expression in erythroblasts using DNA microarrays. To elucidated the gene expression pattern in cytokine, especially IL-6, challenged erythroblasts, in vitro IL-6 treated erythroblasts in EPO containing medium both at day 1 and day 2 were collected. We also sorted the erythroblasts at different stages (Proerythroblasts(I),Basophilic(II) and polychromatic(III) erythroblasts,Orthochromatic(IV) erythroblasts) from both DWT and DKO bone marrow cells through fluorescence activated cell sorting. Total RNA were extracted and processed to hybridize with Affymetrix mouse Clariom S microarrays.

RNA-seq analysis of differentiating human erythroblasts

Project description:Human erythroblasts purified from cord blood were cultured in vitro and FACS-sorted into five highly purified populations representing distinct differentiation stages: proerythroblasts, early basophilic erythroblasts, late basophilic erythroblasts, polychromatophilic erythroblasts, and orthochromatophilic erythroblasts. The methods for culture and sorting experiments are given in Hu et al. 2013. For each RNA-seq library, RNA was isolated from 1x 106 sorted human erythroblasts using RNeasy Plus Mini kits (Qiagen). Libraries were then prepared using Illumina TruSeqTM RNA kits to obtain 50 nt reads. Collaborators at the New Your Blood Center were responsible for erythroblast culture, FACS purification of erythroblast populations, and acquisition of RNA-seq data. Collaborators at U.C. Berkeley and Lawrence Berkeley National Laboratory performed data analysis and experimental validation of alternative splicing in erythroblasts. Results: Differentiating erythroblasts execute a dynamic alternative splicing program that is enriched in genes affecting cell cycle, organelle organization, chromatin function, and RNA processing. Alternative splicing plays a major role in regulating gene expression to ensure synthesis of appropriate proteome at each stage as the cells remodel in preparation for production of mature red cells. Erythroid differentiation stage-specific transcriptome analysis was performed by RNA-seq analysis of highly purified erythroblast populations
