Description
Single cell RNA sequencing of freshly isolated mouse burst forming unit-erythroid (BFU-E) , colony forming unit-erythroid (CFU-E), and intermediate stages of erythroid development cells. Overall design: One 96 well plate with 24 BFU-E, 24 CFU-E, 24 cells with 25-35% expression of CD71/CD24, and 24 cells with 50-60% expression of CD71/CD24.

Description
Single cell mouse BFU-E (burst forming unit-erythroid ) were FACS-deposited into individual wells of a 96-well plate containing PCM either with or without 100 nM dexamethasone. After 16hrs cells from wells that contained a single pair of daughter cells were separated and each individual daughter cell transcriptome was obtained by single cell RNA-seq. Overall design: 13 daughter cells pairs untreated and 13 pairs treated with 100 nM dexamethasone.

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 TGFß receptor (TßRIII) is a potential marker that distinguishes “early” and “late” BFU-Es. Expression of TßRIII 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 TßRIII 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 TGFß 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-ß 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. Overall design: Discovery of BFU-E subpopulations
