About the TCCD

TIME is considered the fourth dimension of all biological processes, operating during development, ageing and disease. The developing embryo is a paradigmatic model to study molecular mechanisms of temporal control, since body structures need to be formed at the right time and place for the generation of a functional new organism. The operation of an embryonic clock (EC) underlying timely progression of embryo development was first evidenced by cycles of avian Hes1 homologue gene expression in muscle and axial skeleton progenitor tissues. The EC involves fundamental signaling pathways such as FGF, Notch, Wnt and is dependent on cyclic negative feedback-driven pulses of transcription. Hes1 oscillations have been further described in limb chondrogenic precursor cells, embryonic neural progenitors and both mesenchymal and embryonic stem cells.

The Temporal Control of Cell Differentiation (TCCD) laboratory is working to understand the mechanisms underlying the pace of this time-keeping mechanism and its role in cell fate specification. Our long-term goal is to unveil EC functional relevance and in both health and disease, identifying mechanistic features which may be amenable to therapeutic intervention.
