Project description:This study aimed to understand the transcriptional networks regulating endoderm specification from HESC and therefore explored the phenotype of CA1 and CA2 HESC constitutively over-expressing SOX7 or SOX17. Cell lines were created using an inducible construct whereby clonal populations containing transgene integration are selected by Neomycin resistance without expressing of the gene of interest (NoCre controls). Transgene expression is induced via Cre-mediated recombination and selected for puromycin resistance (SOX O/E). The phenotype of the resulting cells suggests that SOX7 expressing HESC represent stable extraembryonic endoderm progenitors, while SOX17 expressing HESC represent early definitive endoderm progenitors. Both in vitro and in vivo SOX7 expressing HESC are restricted to the extraembryonic endoderm lineage, while SOX17 expressing HESC demonstrate mesendodermal specificity. In vitro, SOX17 expressing HESC efficiently produce mature definitive endoderm derivatives. The molecular phenotype of the resulting SOX7 and SOX17 expressing HESC was characterized by microarray analysis Experiment Overall Design: Total RNA was extracted from confluent monolayer cultures of SOX7 over-expressing HESC, SOX17 over-expressing HESC, and their respective control parental HESC lines (designated NoCre Sox7 and NoCre Sox17).

Project description:Glioblastoma multiforme (GBM) is a highly aggressive and vascularized malignant brain tumor. SoxF transcription factors consisting of Sox7, Sox17, and Sox18 are expressed specifically in endothelial cells (ECs) and contribute to vascular morphogenesis. While the role of Sox17 was found in subcutaneous ectopic tumors, Sox7 has not been studied in the context of tumor angiogenesis. Here, we investigated gene expression profile of RNA analysis of Sox7- and Sox17-deficient mouse endothelial cells from high grade glioma using RNA sequencing to validate molecular characteristics of Sox7 and Sox17 in high grade glioma.

Project description:Transcription factors play critical roles in stem cell maintenance and differentiation. Using single cell RNA sequencing, we investigated transcription factors expressed in endothelial progenitors differentiated from human pluripotent stem cells (hPSCs) and identified upregulated differential expression of SOXF subgroup members SOX7, SOX17, and SOX18. To test whether overexpression of these factors increases differentiation efficiency, we established inducible hPSC lines and found only SOX17 improved differentiation of CD34+VEC+ cells. Temporal expression analysis of SOX17 and VEC revealed that SOX17 was turned on immediately before VEC, indicating SOX17 may be a causative factor in determining hemogenic endothelial differentiation. Upon Cas13d mediated repression of SOX17, differentiation was significantly abrogated. We found SOX17 forward programming is sufficient to generate more than 50% CD34+VEC+CD73- cells. Further differentiation of SOX17 forward programmed cells generated hematopoietic progenitors that emerged via an endothelial to hematopoietic transition and significantly upregulated definitive hematopoietic transcriptional programs. Our analyses reveal an uncharacterized function of SOX17 in directing hPSCs differentiation towards hematopoietic lineages.
