SRP220528 PRJNA564140 GSE136976 ATAC-seq from erythroid cells generated through ex vivo differentiation CD34+ Haematopoietic stem cells were differentiated under two ex vivo protocols to generate ATAC-seq data for machine learning of rules underlying open chromatin dynamics. Overall design: CD34+ cells were isolated from peripheral blood from three healthy donors (Two males, one female) and differentiatied ex vivo using two different protocols. The first protocol (P1) uses a 2-phase differentiation and the second protcol (P2) uses a 3-phase differentiation which includes co-culture on a layer of stromal MS-5 cells. ATAC-seq was perfroemd at various days throughout differentiation. GSE136976 pubmed 33046896 parent_bioproject PRJNA574096
