In Development this week (Vol. 144, Issue 18)

Here are the highlights from the current issue of Development:   Separating nematode species by spermatogenesis During spermatogenesis, unnecessary organelles and cytoplasmic components are shed from developing sperm in order to streamline them for optimal motility. These components are partitioned into structures known as ‘residual bodies’, which subsequently separate from the sperm and are lost.[…]

Here are the highlights from the current issue of Development:   Computing branching pattern complexity Bile – a fluid that aids digestion – is transported from the liver to the intestine through the bile duct. Bile reaches the bile duct itself via a complex, highly branched structure called the intrahepatic biliary network. This network spreads[…]

Here are the highlights from the current issue of Development:   Heart tube formation: a gut reaction Morphogenesis of the endoderm-derived foregut (FG) is tightly linked to that of the mesoderm-derived heart tube (HT), with both structures arising at approximately the same time and place in the developing embryo. However, the physical forces that create[…]

Here are the highlights from the current issue of Development:   SEGGA: new software for analysing cell shape and dynamics Changes in epithelial cell shape and organisation are essential for tissue morphogenesis, regeneration and repair. In recent years, advances in microscopy have made it possible to capture these changes in living animals, but the quantitative[…]

Here are the highlights from the current issue of Development:   A new niche for human HSCs Human haematopoiesis occurs at various anatomical sites throughout development, including the yolk sac, the aorta-gonad-mesonephros region, the liver, the placenta and the bone marrow. Cells marked by high expression of CD34 and low CD45 – suggestive of possible[…]

In Development this week (Vol. 144, Issue 6) – SPECIAL ISSUE ON ORGANOIDS

Posted by on March 14th, 2017

The current issue of Development – our Special Issue on Organoids – features a collection of review- and research-based articles focusing on organoids. Here are some of the highlights. Happy reading (and thanks to everyone who contributed)!   Organoids: a Special Issue In her Editorial, Melissa Little provides an overview of the entire contents of the[…]

Here are the highlights from the new issue of Development:   Adding a new layer of complexity to pre-eclampsia Pre-eclampsia (PE) is a pregnancy complication associated with abnormal formation of the placenta. To date, most studies of PE have focussed on cytotrophoblasts (CTBs) within the villous placenta (the chorion frondosum); the deficient invasion of these[…]

Here are the highlights from the new issue of Development:   A new mechanism in ESC lineage priming Histone demethylases have recognized roles in the control of gene expression during development and disease, and are typically associated with the remodelling of the chromatin environment. Jmjd2/Kdm4 H3K9-demethylases cooperate in promoting mouse embryonic stem cell (ESC) identity,[…]

Here are the highlights from the current issue of Development:   Evolving an atypical developmental programme with IMM The brown alga Ectocarpus has alternating haploid (gametophyte) and diploid (sporophyte) generations. Morphologically, these are distinguished by a more complex system of basal filaments in the sporophyte, initiated via symmetric divisions before the apical-basal axis is defined[…]

Here are the highlights from the current issue of Development:   ECM: bridging the gap between germ layers The extracellular matrix (ECM) plays crucial roles during morphogenesis but how it is assembled and patterned in vivo is poorly understood. Here, Yuki Sato, Rusty Lansford and colleagues investigate this by examining the distribution of the ECM[…]
