Petter Woll group - Leukemic stem cells
The group studies cellular and molecular mechanisms promoting establishment and propagation of leukemic stem cells. We wish to understand the cellular and molecular targets for highly recurrent mutations in hematologic malignancies, in order to prevent leukemia and treat the patient.
About our research
The major focus of our research program is towards the development and characterization of clinically relevant genetic mouse models to understand the cellular and molecular targets for recurrent leukemic mutations, and how these promote leukemic stem cell clonal advantage. To complement studies in mice, we have access to state-of-the-art patient material (viably frozen bone marrow and peripheral blood) that allows isolation and characterization of distinct hematopoietic stem and progenitor compartments. In addition, the immunological targeting of leukemic propagating cells is explored.
Because of their short half-life, millions of mature blood cells of multiple lineages are continuously replenished from a rare population of uncommitted hematopoietic stem cells (HSCs) which possess the unique ability to self-renew and to develop towards all blood cell lineages. Understanding the precise mechanisms involved in the regulation of this process is of considerable relevance for human health and disease, as these regulatory stages frequently are hijacked in hematologic malignancies.
Advances in next-generation sequencing has revealed highly recurrent mutations in hematologic malignancies. However, at what cellular stage and the molecular impact of these mutations promoting leukemic stem cell expansion, as well as perturbed hematopoietic differentiation, remains poorly understood.
Petter WollGroup Leader, Ph.D., Assistant Professor
Petter Woll received his PhD degree from the University of Minnesota in 2008 after working in the lab of Dan Kaufman focused on modelling human blood development from embryonic stem cells, and continued to study cancer stem cells in patient with myelodysplastic syndromes during his postdoc at the University of Oxford in Sten Eirik Jacobsen’s lab. In 2015, Woll started as an Assistant Professor at the Karolinska Institutet where his lab that is located at the Center for Hematology and Regenerative Medicine is focused on unravelling cellular and molecular mechanisms underlying malignant hematopoiesis. In his spare time, he enjoys sports, including cycling, squash and skiing, and to go to concerts. His all-time top 5 favourite bands are (in no particular order): Bruce Springsteen, Radiohead, Åge Aleksandersen, The National and Nick Cave.
Stina VirdingPhD Student
Stina Virding received her master degree in Biomedicine at Karolinska Institute in 2015. Before she started her PhD she worked at King’s College, London, where she generated and characterized T-induced pluripotent stem cells from ß-cell antigen-specific regulatory T cells. Her PhD project is focused on unravelling at the single cell level the molecular dysregulation underlying leukemic stem cell clonal dominance, clonal evolution and resistance to therapy using a method that combines high-sensitivity mutation detection with whole-transcriptome analysis. Stina loves to travel and to study abroad. During the last years she has been studying at University of Technology Sydney (Australia), XLRI Jamshedpur School of business and Human Resources (India), Leiden University (The Netherlands), Princeton University (USA) and King’s College (England). When she is not busy in the lab she enjoys skiing, sailing, dancing and playing tennis. Stina listens to all kind of music but some of her favourite bands include The Nationals, Bon Iver, First Aid Kit & Bo Kaspers Orkester.
Madeleine LehanderPhD Student
Madeleine Lehander, or Madde as she is usually being called, received her master degree in Biomedicine at Karolinska Institutet in 2020, where she joined the Woll group for her master thesis. She was then working on a project regarding the impact of cell cycle of hematopoietic stem cells in normal and malignant hematopoiesis. After graduating, she stayed in the Woll group as a PhD student where she is now exploring potential elimination of hematopoietic stem cells with TCR-engineered T cells to determine the dependency of HSCs in normal and malignant hematopoiesis. Madde grew up spending all her spare time on the football field but now she also enjoys photography, playing golf and she spends as much time as possible with family and friends. If she is allowed to control the music during dinner parties, it's non-stop Swedish music with Thomas Stenström, Laleh and Mares streaming from the speakers.
Axel WinrothPhD Student
Axel Winroth received his medical degree in January 2020 and joined the Woll lab shortly after. His Phd project aims to investigate transcriptional states associated with lineage bias in hematopoietic stem cell differentiation using single cell RNA sequencing. In addition to stem cell biology he is interested in programming and mathematics and hopes to understand bioinformatics. When not in the lab Axel enjoys drinking coffee and going for walks.
