From our sister journals – November 2016

Posted by on December 2nd, 2016

Here we highlight some developmental biology related content from other journals published by The Company of Biologists.   Chisato Kitazawa and colleagues uncover diversity in the morphological changes of early embryogenesis in closely related sea urchin species.   Ben Steventon and colleagues describe how crainial placode formation in Xenopus involves directional and persistent cell movements   Also using Xenopus, Karl[…]

November in preprints

Posted by on December 2nd, 2016

Our latest monthly trawl for developmental biology (and other cool) preprints. See June’s introductory post for background, and let us know if we missed anything   This month, we found preprints covering various aspects of plant growth and patterning, a lot of cell biology – including insights into microtubules organisation, RNA localisation and yeast size control –[…]

The elusive hematopoietic stem cells of Drosophila.

Posted by on November 22nd, 2016

Drosophila hematopoiesis shows striking resemblance with that of vertebrates, both at the level of signalling molecules and the phase of development. Even though there has been no report of Hematopoietic stem cells (HSCs) in Drosophila, this model has been employed extensively to understand progenitor biology and niche interactions. The Drosophila blood cells are specialised precursor[…]

How to build and evolve a nervous system

Posted by on November 20th, 2016

Author Summary of “A gene regulatory network for apical organ neurogenesis and its spatial control in sea star embryos”.   Alys M. Cheatle Jarvela, Kristen A. Yankura, Veronica F. Hinman Development 2016 143: 4214-4223; doi: 10.1242/dev.134999 Very similar cell types are found across the animal tree of life. Much of animal diversity, therefore, arises not from the formation of new cells, but[…]

Mitotic Bookmarking by Esrrb: an unexplored mechanism for implementing cell fate choices?

Posted by on November 18th, 2016

  The story behind our recent paper (Festuccia et al., Nature Cell Biology 2016) started with a serendipitous observation made in a small room of the ISCR (Institute for Stem Cell Research), which at the time was still located in the King’s Buildings campus, south of town in my beloved Edinburgh. I was imaging a[…]

In Development this week (Vol. 143, Issue 22)

Posted by on November 15th, 2016

Here are the highlights from the current issue of Development:   A postnatal model for Zika virus infection Zika virus (ZIKV) infection results in embryonic microcephaly and has been declared a global health emergency by the World Health Organization. Disruption of the neural progenitor cells is considered to be the major cause of microcephaly; however,[…]

This month on the Node

Posted by on November 11th, 2016

A roundup of the Node’s highlights from October 2016.      October’s most discussed post came from Development’s Executive Editor Katherine Brown, who reported from a workshop on preprints in Cambridge and gave a journal’s perspective on the promises and challenges of preprinting. The comments section is worth reading, as is this recent post from the organiser[…]

From our sister journals – October 2016

Posted by on November 10th, 2016

Here we highlight some developmental biology related content from other journals published by The Company of Biologists.   Helio Roque and colleagues describe that flies lacking MKS, a component of the transition zone in cilia, show abnormalities during development, but not in the adult.   Hua Liu and  Ken-Ichi Nonomura describe large scale chromatin remodelling in meiosis[…]

October in preprints

Posted by on November 2nd, 2016

Our latest monthly trawl for developmental biology (and other cool) preprints. See June’s post for background, and let us know if we missed anything This month features quite a bit of cell biology, both in early embryos and in a dish, with work on microtubules from the labs of Andreas Prokop, Tim Mitchison and Manuel Thery.[…]

From our sister journals – September 2016

Posted by on October 7th, 2016

Here we highlight some developmental biology related content from other journals published by The Company of Biologists. Moran Neuhof, Michael Levin and Oded Rechavi explored the relationship between regeneration and inheritance in planaria    Ryo Nozu and colleagues provide evidence for lipid histotrophy in great white shark reproduction from a shark accidentally caught by fishermen in Okinawa.  […]
