Per Uhlén is Professor of Cell Signaling in the Unit of Molecular Neurobiology at the Department of Medical Biochemistry and Biophysics (MBB), Karolinska Institutet

Research description

Research Insterests​​

Per Uhlén’s research group is studying cancer and developmental related processes in various types of cells. The biological platforms that we are applying are tumor samples, tissue slices, primary cell cultures, cell lines and stem cells. To study the processes of cell signaling, cell division, cell differentiation, and neural migration/networking we are applying state-of-the-art imaging techniques, such as 3D light-sheet microscopy and tissue clearing, advanced analysis tools, such as Fourier transform and deep learning, and modern genetic tools, such as transgenic animals. Our focus is to shed light on the intracellular cell signaling mechanisms and biological processes involved in disease and development. We are particularly interested in calcium signaling and how cells are modulating and decoding the frequency/amplitude of intracellular calcium oscillations.
