Molecular cancer and stem cell therapeutics
Ninety percent of all cancer deaths arise from tumor metastasis, a process that depends on the delamination and spread of tumor cells. Only a minority of the tumor cells, i.e. tumor-initiating cells also referred to as cancer stem cells (CSCs), are capable of successfully seeding a distant site. The CSC hypothesis proposes that only a subset of tumor cells have the ability to self-renew and are thus responsible for driving tumorigenesis, making them ideal targets for cancer intervention.
Our research group focuses on the early steps of the metastatic process, i.e. migration and invasion of the tumor cells into circulation through a process known as epithelial to mesenchymal transition (EMT) and the mechanisms controlling this process. Recent discoveries have provided the compelling evidence that during the process of EMT cells are converted into cancer stem cells (CSCs). The fact that cells acquire stem-like traits during the process of migration, invasion and intravasion i.e. EMT, opens up a new and exciting area of research - merging stem cell biology and cancer biology. It also highlights the need for further EMT research within the cancer field.

Our main interest is to gain a better understanding of cellular changes that induces EMT and conversion to CSCs. We are studying the role of cell signaling such as TGFb and Wnt and its role in migration and spread of cancers including breast and glioma using both in-vitro and in-vivo models. Of particular interest is the emerging area of epigenetics and metabolism and its importance for EMT. Another interest is in menchanobiology thus how mechanical pressure within the tumors micro/nanoenvironment will affect metastasis. Our long-term goal is that these studies will provide significant insight into the complex mechanism of tumor spread and metastasis and ultimately allow for our research to advance into a clinical setting.
Currently, we have several ongoing national and international research projects within these areas and our laboratory places a special focus on international collaborative efforts. It is our ambition to create a unique laboratory and educational environment that is not limited by departmental or national barriers but only by our scientific education, curiosity and ambition.
