new paper by the kiehart lab showing how calcium fluxes control force generation during dorsal closure

Tension-oriented cell divisions limit anisotropic tissue tension in epithelial spreading during zebrafish epiboly

great work by campinho et al ;)

New paper on wound healing in Drosophila embryos

Paper by Rodrigo Fernandez-Gonzalez and Zallen analyzing wound healing and actomysin cable formation in different stages of embryogenesis

Interesting role of Rab11+ vesicles in regulating actin dynamics and meiotic spindle positioning in the mouse oocyte

Interesting review

for calcium fans

one more from lecuit

Imaging ROS signaling in cells and animals

Antunes et al...

...e com direito a cover e comentario! ;)

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 ;)

septate junctions have an important role in establishing the gut immune barrier

The Hammerschmidt lab establishes adult zebrafish as a model for skin wound healing

New paper by will wood's lab on the role of SCAR for wound healing and phagocytosis of apoptotic corpses by hemocytes

New paper from the Millard lab showing that PIP3 is required for actin protrusion formation during dorsal closure and wound healing. They show this is controlled by bazooka and pten, which are downregulated at the leading edge junctions, both in DC and in WH.
