From 22 – 24 August 2019 Peter ten Dijke’s group hosted an international meeting on “TGF-beta signalling in cancer” in Leiden. There were 60 participants, including many PhD-students and postdocs from Sweden, Japan and the Netherlands, who presented their unpublished findings and ideas. At the start of this closed meeting, Oncode Institute investigators were invited for an emerging technologies session on single cell analysis, intravital imaging, Crispr/Cas9/tumor organoid and chemical (activity) probes. Regular and flash talk presentations were complemented with break-out sessions.
