We bestuderen besluitvorming over het lot van cellen met embryonale stamcellen als modelsysteem. Stamcellen verwerken een groot aantal stimuli, waarmee ze de ontwikkeling in een grote verscheidenheid aan celtypen aansturen. Met behulp van single-cell transcriptomics en single-molecule microscopy in combinatie met machine learning en wiskundige modellering proberen we de dynamiek van het besluitvormingsproces en het samenspel van interne factoren (epigenetica, celcyclus, stochastische genexpressie) en externe factoren ( signaalmoleculen, cel-celcontacten, mechanische aanwijzingen) te ontrafelen. Wij zijn van mening dat de door ons onderzoek ontdekte basisprincipes van grote waarde zullen zijn voor toepassingen in de regeneratieve geneeskunde en de bestrijding van kankerstamcellen.
