Ddit3 Remodels the GMP Transcriptional Landscape around Gata2
(A) Transcriptional networks of GMPs transduced with CSIEm and Ddit3 and after 2-day culture under multilineage differentiation conditions. Network inference and representation are as in Figure 2. Highlighted in color are differential regulatory hubs (Gata2, Csf3r, and Mpo); their connectivity is quantified in Figure S4A.
(B) GSEA of early progenitor-affiliated signatures in the transcriptional programs of CSIem- and Ddit3-transduced GMPs is shown.
(C) Diagram shows Ddit3-driven lineage remodeling of GMPs.
(D) Connectivity of the differential regulatory hubs in (A) upon culture of Ddit3-transduced GMPs. Networks are represented in (A) and Figure S4D.
(E) GSEA of Gata2 targets in CSIem- and Ddit3-transduced GMPs. Transduced cells in (B, D, and E) were cultured for 2 days under multilineage differentiation conditions.
