Insects rock...

...in the organ growth field ;)

inositol kinase and InsP4 make the wave faster

new paper by enrique amaya's lab showing the requirement of inositol kinase and inositol tetrakisphosphate for wound healing and for the propagation of the calcium wave

Mobile E-cadherin pool in dorsal/ventral membranes of embryonic epidermal cells prevents cells from crossing segment boundaries

Paper from N. Brown's lab shows that MTs are required for asymmetric distribution of E-cad/Bazooka in embryonic epidermal cells via RhoGEF2. Check also short comment on the same issue

Special focus on Morphogenesis on this week's Science issue

Special issue includes review by Guillot and Lecuit on epithelial morphogenesis

Check out the current issue of Dev Cell

Many interesting papers on Dev Cell this week, including an article on compensatory cell growth and cell competition in Drosophila, and a new paper by the Bellaiche lab on AJ remodeling regulated by PTEN

"Actin draws a cadherin crowd"

Binding to F-actin guides cadherin cluster assembly, stability, and movement

The role of transcription-independent damage signals in the initiation of epithelial wound healing

very interesting review on wound healing ;)
