TGF-β inhibitors stimulate red blood cell production by enhancing self-renewal of BFU-E erythroid progenitors

Project description:Erythroid progenitor BFU-Es are so-named based on their ability to generate in methylcellulose culture large colonies of erythroid cells that consist of “bursts” of smaller erythroid colonies derived from the later CFU-E Epo- dependent progenitors. “Early” BFU-E cells forming large BFU-E colonies presumably have higher capacities for self-renewal than do those forming small BFU-E colonies. In order to understand the mechanism underlying this heterogeneity, we conducted single cell transcriptome analysis on BFU-E cells purified from mouse embryos. Our analyses showed that there are two principal subgroups of mouse BFU-E cells and that the type III TGFβ receptor (TβRIII) is a potential marker that distinguishes “early” and “late” BFU-Es. Expression of TβRIII is correlated with that of GATA1, a gene encoding an erythroid transcription factor induced during the BFU-E to CFU-E transition. The mouse and human BFU-E sub populations (TßRIII10%lo) expressing the 10% lowest amount of surface TβRIII are indeed enriched for early BFU-Es, and are significantly more responsive to glucocorticoid stimulation, which promotes BFU-E self-renewal, as compared to the total BFU-E population. The TßRIII10%lo BFU-E subpopulation presumably represents earlier BFU-Es with maximal capacity for self-renewal. Consistent with this notion, signaling by the TGFβ receptor kinases RI and RII increases during the transition from early (TßRIII10%lo) to late (TßRIII10%hi) BFU-Es and then decreases in CFU-E cells. Blocking TGF-β signaling by receptor kinase inhibitors increase TßRIII10%lo BFU-E cell self-renewal and increases total erythroblast production, suggesting the use of this type of drug in treating Epo unresponsive anemias.

Isolation and Transcriptome Analyses of Human Erythroid Progenitors: BFU-E and CFU-E

Project description:Burst-forming unit-erythroid (BFU-E) and colony-forming unit-erythroid (CFU-E) cells are erythroid progenitors traditionally defined by colony assays. We developed a flow cytometry-based strategy for isolating human BFU-E and CFU-E cells based on the changes in expression of cell surface markers during in vitro erythroid cell culture. BFU-E and CFU-E are characterized by CD45+GPA-IL-3R-CD34+CD36-CD71low and CD45+GPA-IL-3R-CD34-CD36+CD71high phenotypes, respectively. Colony assays validated phenotypic assignment giving rise to BFU-E and CFU-E colonies, both at a purity ~90%. The BFU-E colony forming ability of CD45+GPA-IL-3R-CD34+CD36-CD71low cells required SCF and erythropoietin, while the CFU-E colony forming ability of CD45+GPA-IL-3R-CD34-CD36+CD71high cells required only erythropoietin. Bioinformatic analysis of the RNA-seq data revealed unique transcriptomes in each differentiation stage. The sorting strategy was validated in uncultured primary cells isolated from bone marrow and peripheral blood, indicating that marker expression is not an artifact of in vitro cell culture, but represents an in vivo characteristic of erythroid progenitor populations. The ability to isolate highly pure human BFU-E and CFU-E progenitors will enable detailed cellular and molecular characterization of these distinct progenitor populations and define their contribution to disordered erythropoiesis in inherited and acquired hematological disease. Our data provide important resource for future studies. Transcription profiles of Human erythroid progenitors at distinct developmental stages were generated by deep sequencing, in triplicate, using IlluminaHiSeq 2000. The complete dataset comprises 4 sample types: CD34, BFU, CFU, and Pro (reanalysis of GSM1304777-GSM1304779).
