The general aims of the division of Experimental Hematology are to obtain detailed knowledge on (molecular) mechanisms that determine hematopoietic stem cell self-renewal and differentiation, with the ultimate goal to deepen our insights in the development of human leukemias. We have a specific interest in dissecting the clonal heterogeneity of leukemias and recently developed tools that allow us to identify and prospectively isolate genetically distinct clones within individual patients. We perform gene-function analyses in human hematopoietic stem and progenitor cells isolated from cordblood and bone marrow utilizing various strategies including optimized retro/lentiviral transduction protocols and inducible RNAi and CRISPR/Cas9 approaches. We have a longstanding expertise in using molecular approaches (transcriptome, proteome and epigenome) to further understand processes such as hematopoietic differentiation, proliferation, apoptosis and self-renewal. We utilize a series of cell biological in vitro and in vivo model systems to be able to translate knowledge from our molecular research lines to more general concepts of hematopoietic stem cell biology. We make use of sophisticated humanize niche xenograft models in order to mimic that situation in leukemia patients as closely as possible. Furthermore, we directly collaborate with the clinical and diagnostic departments at the UMCG and have banked large series of leukemic patient material and are currently focusing on elucidating whether leukemic stem cells exist, what their phenotype is, which mechanisms result in enhanced self-renewal and a disturbed differentiation profile, and whether we can restore the normal hematopoietic differentiation program by e.g. interfering at the genetic level or by utilizing novel therapeutical agents. We anticipate that our studies will lead to a more rational approach in the clinic of this highly malignant disorder.

Our consortium Physics of Cancer: Cancer as a Materials Science problem was awarded by the ZIAM. For details see our website. The aim of this current program is to study the stiffness of cells and tissues for two partially opposing types of cancer by means of careful experiments and multiscale computational modelling. Subsequently, we aim to identify key malfunctioning proteins inside cells, on the cell membrane as well as in the extracellular matrix, by a combination of computational modelling, structure analysis and mutation studies. Interference with these proteins could become a future target to prevent the release of cancer cells from a tumour, invasion and further development of the tumour. Five PhD students will embark on this ambitous project. Great collaboration between the ZIAM/RUG and UMCG. Laura Dillingh will start early September as one of the PhD students!

We performed transcriptome and ChIPseq experiments to compare direct and indirect targets of MLL-AF9. We conclude that BRD3/4 and the FLT3-TAK1/NF-kB pathways collectively control a set of targets that are critically important for the survival of human MLL-AF9 cells. Marco published his work in Plos ONE, which was a collaborative effort together with the Joost Martens lab in Nijmegen.

Further improvement of the humanized niche xenograft model! We genetically engineered human MSCs to secrete human interleukin-3 (IL-3) and thrombopoietin (TPO). In vivo, these genetically engineered MSCs maintained their ability to differentiate into bone, adipocytes, and other stromal components. Upon transplantation of MLL-AF9-transduced CB CD34+ cells, acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) developed in engineered scaffolds, in which a significantly higher percentage of myeloid clones was observed in the mouse compartments compared with previous models. This approach will be useful for functional study of the importance of niche factors in normal and malignant human hematopoiesis. Work by Marco and Bauke, published in Experimental Hematology.

Antonella publishes her work on the development of improved humanized niche xenograft models. By implanting ceramic scaffolds coated with human mesenchymal stromal cells into immune-deficient mice, we were able to mimic the human bone marrow niche. Thus, we have established a human leukemia xenograft mouse model in which a large cohort of patient samples successfully engrafted, which covered all of the important genetic and risk subgroups. We found that by providing a humanized environment, stem cell self-renewal properties were better maintained as determined by serial transplantation assays and genome-wide transcriptome studies, and less clonal drift was observed as determined by exome sequencing. The human leukemia xenograft mouse models that we have established here will serve as an excellent resource for future studies aimed at exploring novel therapeutic approaches. The was a collaboration with Richard Groen, and was published in Blood. Also got the cover image and Inside Blood editorial.

Marta Capala published a paper in Plos ONE showing that RAC2 fulfils an essential role in BCR-ABL transformed cells. Time-lapse confocal microscopy surprisingly revealed very distinct localisation of RAC1 and RAC2 in human hematopoietic stem/progenitor cells. Proteome studies to identify RAC1 and RAC2 interactomes revealed that RAC2 interacts with a set of mitochondrial proteins including mitochondrial transport proteins SAM50 and Metaxin 1. Downregulation of RAC2 or SAM50 impaired self-renewal associated with a decreased mitochondrial membrane potential and impaired mitochondrial integrity as determined by EM.
