Third colloquium on cellular signal transduction: cell-cycle signalling. German Cancer Research Centre Heidelberg, 14 January 1994.

The annual meeting of the DKFZ research programme Tumor Cell Regulation was originally conceived by its members as an internal forum for mutual information and progress discussion with their cooperating groups. However, because the attractive topics and contributions, these colloquia receive increasing attention also from non-members of the Tumor Cell Regulation programme and, this year, the number of the external participants exceeded even that of the internal members. We therefore anticipate this activity becoming a traditional event of wide interest.
