Functional Dissection of Transcription Factor Networks Governing Haematopoietic Progenitor States

Project description:Blood is generated by a constant stream of differentiating haematopoietic progenitor cells. The process is controlled by an immensely complex gene regulatory networks. These have been difficult to comprehend using correlative evidence and limited systematic functional data. Hoxb8-FL cell line is a model system of lympho-myeloid progenitors, which self-renews in vitro and is amenable to genetic perturbations. To construct a functionally defined transcription factor (TF) network we targeted 39 transcription factors using CRISPR/Cas9 gene targeting in Hoxb8-FL cells. We measured the resulting transcriptional changes by small scale RNA-Seq within 2-4 d of each perturbation. Our network analysis revealed >17,000 TF-target interactions across >7,000 target genes, established new interactions among TFs and shed new light on the mechanisms maintaining self-renewal and multipotency.

Transcriptional networks controlling the development and differentiation of haematopoietic stem progenitor cells

Project description:Our focus is to investigate the regulatory networks which are involved in the development and subsequent differentiation of haematopoietic stem and progenitor cells. The aim is to identify new targets and co-operative binding partners of established stem cell transcription factors as well as identifiying new important transcriptional regulators.

Competing dynamic gene regulatory networks involved in fibroblast reprogramming to haematopoietic progenitor cells [scRNA-Seq]

Project description:Direct reprogramming of somatic cells offers a potentially safer therapeutic approach to generate patient-specific haematopoietic cells. However, this strategy is limited by stochasticity of reprogramming. Investigating the gene-regulatory networks involved during reprogramming would help generate functionally relevant cells in adequate numbers. To address this, we developed an inducible system to reprogram fibroblasts to HSPCs by ectopically expressing the two transcription factors SCL and LMO2. Transcriptome and epigenome analysis at different stages of reprogramming revealed uniform silencing of fibroblast genes and upregulation of the haemogenic endothelial program. Integrated analysis suggested that TFs FLI1, GATA1/2, KLF14 are direct targets of SCL/LMO2, which subsequently induce the haematopoietic programme. Single cell RNA-Seq revealed conflicting and competing fate decisions at intermediate stages of reprogramming. Inhibiting signalling pathways associated with competing neuronal fate significantly enhanced haematopoietic reprogramming efficiency. In conclusion, this study identifies early/intermediate reprogramming events and associated pathways that were targeted to improve reprogramming efficiency.
