BIOSS Area B: Supra-cellular Signalling Pathways
During development, growth, and regeneration, complex signalling environments recruit cells from stem cell pools, direct their differentiation paths, and organise them in 3D into specialized organ structures. Research in BIOSS-B focuses on the molecular nature, organization, and logic of these signalling systems.
BIOSS-B1 analyses how individual cells sense the signals from their environment and translate this information into cell fate decisions. A focus is on stem cell populations and their niches.
BIOSS-B2 investigates stem-cell like proliferative populations in cancer with a focus on tumour development, both at the intracellular level of oncogenic kinase signalling, as well as at the supracellular level of cell-cell communication within tumours.
The subject of BIOSS-B3 it will be to investigate how biochemical and biophysical inputs from the environment are interpreted by cells in the formation of tissues.
BIOSS-B combines analytical approaches with synthetic signalling systems to verify hypotheses and to advance understanding of control mechanisms both in animal and plant systems. Together with BIOSS-C, we design artificial microenvironments to control stem cell behaviour and cell differentiation.
