Asymmetric division is a widespread mechanism for generating cellular diversity during developmental patterning. The stomata of flowering plants are epidermal valves that regulate gas exchange, and provide an accessible system to investigate the mechanisms of asymmetric cell division both within and across species. A paper in the new issue of Development reports an investigation of the molecular control of this[…]

Contact inhibition of locomotion is a widespread phenomenon in migrating cells. However, cells often migrate collectively as a sheet, raising the question of how contact inhibition is overcome in these scenarios. A new paper in Development addresses this problem by studying the signals that regulate collective migration in Xenopus leading edge mesendoderm (LEM) cells. We[…]

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[…]

Somites are segmented structures  which give rise to numerous tissues in the vertebrate body. It has long been observed that somites scale in size with the overall size of the embryo, both as development proceeds and between individuals of different sizes, but the molecular underpinnings of this process have remained controversial. A new paper in[…]

Short CLE peptides regulate a wide variety of processes during plant development. In the developing root, the receptors and co-receptors for CLEs have remained largely unclear, as have the relationships between different CLEs and different (co-)receptors. A new paper in Development addresses this problem by reporting a new receptor kinase involved in CLE signaling. We caught[…]

The vertebrate lymphatic vascular network provides crucial circulatory and immune functions but its developmental origin has been a contentious issue, in particular the question of whether lymphatic endothelial cells have an exclusively venous origin. A new paper in Development addresses this issue in the dermis of the mouse embryo. To find out more about the[…]

Intrahepatic bile ducts (IHBDs) are epithelial tubular structures that transport bile from the liver to the intestine, but the molecules and mechanisms controlling IHBD morphogenesis have remained largely unclear. A a recent paper in Development reports an investigation into IHBD development and the role the tumour suppressor and cytoskeletal regulator Merlin plays in the process. We caught[…]

The transition to multicellularity in eukaryotes appears to be intimately linked to the transition from isogamy (gametes of the same size) to anisogamy (gametes of distinct sizes), and indeed to oogamy, a form of anisogamy with a large, immotile egg and a motile sperm. Volvocine algae provide a useful and fascinating model to study how[…]

BSDB 2018: Meet the speakers & chairs

Posted by on April 12th, 2018

Here at Development towers the excitement is mounting for the BSDB’s Spring meeting, which starts in Warwick on Sunday. The meetings are always great fun but this year promises to be particularly special – the society is celebrating its 70th  birthday and has assembled an all star cast of speakers.     The epic conference poster[…]

Cell fate commitment relies on both activation of appropriate genes and suppression of inappropriate ones. Polycomb group proteins are known to be crucial epigenetic silencers of developmental genes, but the manner by which they control fate in vivo, and the relative roles of different Polycomb proteins in silencing, have remained unclear. A new paper in Development[…]
