Developmental Hematopoiesis

Our research


Hematopoietic (blood) stem cells (HSCs) are rare but highly potent cells located in the bone marrow that have an ability to produce all types of blood cells (multilineage capacity) and to give rise to new stem cells (self-renewal). These properties enable an individual to maintain blood cell production over a lifetime.

Our research focus on how HSCs and their immediate offspring are regulated. Although HSCs are associated with a fairly clear functional definition regarding their potentials, all HSCs do not behave the same. One example is during fetal development, where HSCs can give rise to certain specialized blood cells that are not regenerated in adults.

Our goal is to understand what controls HSCs and the fate of other immature blood cells in normal and disease-contexts (leukemia). Enhanced knowledge in this area can be used both preventively and therapeutically, by being able to expand the use of HSC transplantation as a therapy, but also in the development of HSC-based therapies that do not involve direct transplantat ion.

We use advanced cell sorting and a range of cellular and newer molecular biology techniques, including massive parallel-sequencing and Cas9/Crispr-based approaches, many which are applied at the level of single cells. We apply and develop novel transgenic mouse models.
