Research Interests

Developmental biology traditionally considers that development comprises four different events: differentiation, morphogenesis, growth and reproduction. We draw our attention to a fifth issue: How is time controlled during embryonic development? During my PhD, I identified for the first time a cycling gene, hairy1, unveiling the existence of a molecular clock that underlying chick somite formation (Palmeirim et al., 1997 Cell 91, 639-648) and providing cellular positional information in at least two dimensions: not only in the anteroposterior but also in the mediolateral PSM axis (Freitas et al., 2001 Development, 128 (24): 5139-47). Later on, we have identified the chick terra gene and showed that this is an early left-sided expressed gene that links left-right patterning with bilateral synchronization of the segmentation clock (Saúde et al., 2005 Nat Cell Biol, Sep; 7(9): 918-20). In 2007, we reported the existence of a limb molecular clock suggesting that temporal control exerted by cyclic gene expression can be a widespread mechanism providing cellular temporal information during vertebrate embryonic development (Pascoal et al., 2007 J. Mol. Biol., Apr 27;368(2):303-9). Currently, several lines of investigation are being developed aiming to characterize the segmentation clock in several of its aspects. Additionally, we are undertaking studies in both tail and limb buds, in pursuit of molecular parallelisms between the clocks ticking in these tissues.
