Matteo A. Molè & Andrew J. Copp Molè et al., Integrin-Mediated Focal Anchorage Drives Epithelial Zippering during Mouse Neural Tube Closure. Dev. Cell. 52, 321-334.e6 (2020). Zippering is a striking phenomenon whereby two opposing epithelial tissues become progressively united in one direction over a period of time. Similar, to the travel of a zip fastener,[…]
Here is some developmental biology related content from other journals published by The Company of Biologists. Gastrointestinal stem cells in health and disease This Review from Li and Jasper highlights recent findings on intestinal stem cell (ISC) diversity in the GI tract of Drosophila, focusing on the role of ISCs in[…]
The story of our recently released Development paper ‘FatJ acts via the Hippo mediator Yap1 to restrict the size of neural progenitor cell pools’ (http://dev.biologists.org/content/138/10/1893.full) involves hundreds of dozens of fresh free-range eggs and not trivial amounts of time spent peering down a microscope. I have written this with Nick van Hateren, who is the joint first author of this paper along with me.
Pak1-ing a punch in lumen formation The generation and maintenance of correct lumen size and shape is essential for the function of tubular organs. Now, Monn Monn Myat and co-workers report that p21-activated kinase (Pak1) plays a novel role during lumen formation in Drosophila embryonic salivary glands (see p. 4177). The researchers show that Pak1[…]
The current issue of Development is now online! Here are the research highlights: Klf5: a multifaceted regulator of cell fate Kruppel-like transcription factors (Klfs) induce and maintain pluripotency in embryonic stem cells (ESCs), and Klf4 is one of the factors used to create reprogrammed iPS cells. The role of Klfs in the specification of the[…]
Here are the research highlights from the current issue of Development. You can find these on the Development site but we thought it would be useful to have them posted on the Node, too. Brainy signals for actin dynamics During brain development, neurite outgrowth and neuronal migration establish the brain architecture needed for brain function.[…]
