Sara Wickström studied medicine at the University of Helsinki, Finland and absolved a M.D/PhD. program receiving her MD in 2001 and PhD in 2004. In 2010 she was appointed as a Max Planck Research Group Leader at the Max Planck Institute for the Biology of Ageing in Cologne, Germany. Her research addresses a set of fundamental questions in the fields of regenerative medicine and cancer biology: What are the mechanisms that control the stem cell state? How can this phenotype be dynamically adapted to the changing need of an organ/organism?How are the unique properties of stem cells harnessed during malignant transformation and compromised during aging?Her group uses mammalian skin epidermis as a model to study how stem cell behaviour, tissue morphogenesis, and homeostasis iscontrolled by cell and tissue-level mechanics as well as by chemical and physical interactions between different cell types and the extracellular matrix. In addition, she investigates how these processes are perturbed during ageing and age-related disease such as cancer.

 

The Wickström lab combines mouse genetics and human patient material with state-of-the-art scale-bridging technologies from nanoscale atomic force microscopy and next generation sequencing to novel ex vivo culture methods and whole organism live imaging and in silico modeling. Her research is highlyinterdisciplinary and involves collaborations with mathematicians, physicists and clinical oncologists. Recent work from the Wickström group has uncovered how generation of cellular forces is important for the remodelling of the extracellular matrix and how the precise composition of this extracellular matrix niche in turn controls stem cell fate. Furthermore her laboratory has discovered how extrinsic forces generated by the tissue impact chromatin structure and epigenetic gene silencing, thereby controlling the transcriptional state and lineage commitment of stem cells.
