The hematopoietic system is maintained through the continuous generation of new mature effector cells from self-renewing multipotent progenitors. A major challenge for the field is to understand mechanisms behind this differentiation process.

Our research mainly focuses around the developmental progression from stem and progenitor cells into mature B-lymphoid cells and the transcriptional networks that drive this process. We study this through a combination of in vivo models and cell- and molecular biology techniques.

Overall aim is to understand the differentiation process and through this increase our understanding of diseases that originate from developmental defects such as cancer and various immunodeficiencies.

Projects

The hematopoietic system is maintained through the continuous generation of new mature effector cells from self-renewing multipotent progenitors. Development of mature cells occur gradually through series of hierarchically related developmental stages.

This gradual process coupled with the relative ease by which different developmental stages can be purified (based on stage and lineage specific surface markers) make hematopoiesis an ideal system for studying developmental progression. In particular the development of B-cells has been very well characterized leading to the identification of several successive stages of B-cell development. In addition a hierarchically organized network of transcription factors has been identified. This network includes several transcription factors (EBF1, E2A, PAX5, FOXO1 and others), all demonstrated to be critical for proper development and commitment to the B-cell lineage. Together this makes the development of B-cell possibly the most well understood developmental pathways to date.

However, even though the developmental pathway is well defined, our understanding of the molecular mechanisms that drive differentiation and lineage specification is still limited. Thus, a major challenge for the field is to understand how elaborate transcriptional programs drive these processes through temporal and cell-type specific gene expression.

Studies will explore the developmental progression from stem and progenitor cells into mature B-lymphoid cells and the transcriptional networks that drive this process.

More specifically, studies will be aimed at:

  1. Increasing our ability to resolve discrete stages of developmental progression.
  2. Using high resolution cell separation, coupled to genome wide approaches, to study changes in transcription factor usage with resulting effects on epigenetic marks and transcription in association with developmental progression.
  3. Identification and study of distal regulatory elements and how these interact with and modulate their transcriptional targets.
