From stem cells to human development: Meeting report

Posted by on November 15th, 2018

In  September, Development held the third of its highly successful series of meetings focusing on human developmental biology. Here at the Node we ran a competition to find a meeting reporter who would share their experiences of the meeting in exchange for free registration. Competition winner Antonio Barral Gil, a PhD student in Miguel Manzanares’ Lab at[…]

Clone Wars: A New Model

Posted by on October 1st, 2018

From the MRC Weatherall Institute of Molecular Medicine blog.   Stem cell turnover and tissue maintenance is a stochastic process. This means that a randomly occurring mutation has an unknown chance of becoming fixed and spreading within a tissue. Clonal mutations have been observed in apparently healthy tissue, increase in frequency with age and –[…]

During early mouse development, a series of signalling interactions breaks the symmetry of the egg cylinder, spatially organising the embryo into territories that define the future axes of the body. Symmetry breaking can also be observed in embryonic stem cell (ESC) colonies cultured on micropatterned substrates, which thus provide a powerful system to test the[…]

The neural crest is a progenitor population with the capacity to contribute to all vertebrate germ layers. The transcription factor and signalling pathway activity underlying this remarkable pluripotency have been well studied, but the role of the epigenetic state is less well understood. A new paper in Development examines the role of histone acetylation in regulating[…]

Testing Zimmermann’s Telome Theory

Posted by on August 1st, 2018

A perspective on our recent paper ‘CLAVATA was a genetic novelty for the morphological innovation of 3D growth in land plants’1.   In the 1950’s, the German botanist Walter Zimmermann (photo here) hypothesized a series of developmental transitions enabling plant forms to radiate during evolution2. Zimmermann’s so-called Telome Theory has received much attention from those[…]

Differentiating cells mechanically limit progenitor cells’ interkinetic nuclear migration to secure apical cytogenesis

Posted by on July 17th, 2018

Press release for Yuto Watanabe, Takumi Kawaue and Takaki Miyata‘s new Development paper   Key Points Developing brains use a mechanism like the Otoshi-buta (the drop lid), a kitchen wisdom. Differentiating cells in embryonic cerebral walls form a dense filter-like layer to mechanically barrier nuclei of neural stem cells. Loss of this barrier or fence results in[…]

Postdoctoral Position in Pluripotency, Signaling and Epigenetics, Washington University School of Medicine

Posted by on July 13th, 2018

A postdoctoral position is available in the lab of Thorold Theunissen at Washington University School of Medicine in St. Louis, Missouri, USA (theunissenlab.wustl.edu). Our research program is dedicated to exploring the molecular regulation of pluripotent stem cells and their applications in regenerative medicine. We have developed methods for inducing and maintaining human embryonic stem cells[…]

PostDoc Position on Ageing and Fertility in the Payer Lab (CRG Barcelona)

Posted by on July 11th, 2018

We are looking for a highly skilled and motivated candidate to join our group for a PostDoc position. In the Payer lab (http://www.crg.eu/bernhard_payer), we study epigenetic reprogramming in the mammalian germ line and the effects of ageing on fertility. In this project the prospective candidate will study the molecular links between ageing and oocyte quality decline[…]

Stem cell makes its own niche: the story behind the paper

Posted by on July 7th, 2018

In our recent paper published in Nature, we unravel a new mechanism of an extracellular matrix protein secreted by muscle satellite (stem) cells, thereby playing the unusual role of acting as a signaling molecule to maintain the stem cell population. Here, I share the story behind this discovery and discuss the questions related to niche[…]

Blastoid: the backstory of the formation of blastocyst-like structure solely from stem cells.

Posted by on June 27th, 2018

In our recently published paper1, we showed that mouse stem cells self-organize into blastocyst-like structures, that we termed blastoids. Because blastoids can be generated in large numbers, can be finely manipulated, and implant in utero, they are a powerful tool to investigate the principles of pre- and post-implantation development. Here is the backstory of our[…]
