A clock in limb patterning
Caroline Sheeba, Raquel Andrade and Isabel Palmeirim have recently published a featured perspective article in the Journal of Molecular Biology. In this article they present an integrated temporal and spatial model for limb patterning, proposing that the limb Clock may allow temporal information to be decoded into positional information when the distance between opposing signaling gradients is no longer sufficient to provide distinct cell fate specification. The authors were also invited to prepare a figure for the cover of the Journal of Molecular Biology! See the JMB website.
Drosophila axis elongation
Sérgio Simões, who did his PhD work in António Jacinto's lab, has recently published part of his postdoctoral work in New York in the Journal of Cell Biology. In this paper, the authors show that Rho GTPase and Shroom actin-binding protein have distinct roles in Rho-kinase localization and actomyosin contractility during Drosophila axis elongation.
