Research description

Research Insterests​​

Per Uhlén’s research group is studying developmental and cancer related processes in various types of cells. The biological platforms that we are applying are tissue slices, primary cell cultures, cell lines and stem cells. To study the processes of cell division, cell differentiation, and neural migration/networking we are applying state-of-the-art imaging techniques and modern genetic tools, such as transgenic animals. Our focus is to shed light on the intracellular cell signaling mechanisms that regulate these vital processes for development and disease. We are particularly interested in calcium signaling and how cells are modulating and decoding the frequency/amplitude of intracellular calcium oscillations.
