Cover: A three-dimensional reconstruction of an embryonic day 10.5 mouse from the front using microcomputed tomographic imaging. Images were acquired using a Bruker SKYSCAN 1272 at 3 μm/pixel, reconstructed using SkyScan NRecon, and visualised with CTVox and Imaris software. See Research article by Martínez Traverso et al. (dev200860).

Cerebellum lineage allocation, morphogenesis and repair: impact of interplay amongst cells
Summary: This Review gives an overview of cerebellum development and morphogenesis, which is orchestrated by the coordinated action of cells from various lineages, some of which exhibit plasticity upon injury.
STEM CELLS AND REGENERATION
Coupled myovascular expansion directs cardiac growth and regeneration
Highlighted Article: Coupled expansion of cardiac endothelial cells and cardiomyocytes within a myovascular niche regulates cardiac growth and regeneration in neonatal mice and likely humans.
Hemocytes are essential for Drosophila melanogaster post-embryonic development, independent of control of the microbiota
Highlighted Article: Hemocyte ablation in Drosophila melanogaster with a novel strong hemocyte-specific driver causes pupal lethality under germ-free conditions.
C. elegans srGAP is an α-catenin M domain-binding protein that strengthens cadherin-dependent adhesion during morphogenesis
Summary: Genetic, biochemical and imaging experiments demonstrate a role for SGRP-1 in stabilization of adherens junctions by binding to the HMP-1 M domain during C. elegans embryonic morphogenesis.
Retrovirus-derived RTL5 and RTL6 genes are novel constituents of the innate immune system in the eutherian brain
Highlighted Article: RTL5 and RTL6 are eutherian-specific genes acquired from a retrovirus in microglia in the brain. They play important roles in pathogen clearance in the eutherian brain immune system.
Pivotal role of STIP in ovule pattern formation and female germline development in Arabidopsis thaliana
Summary:STIP plays a key role during ovule development in Arabidopsis thaliana by controlling integument formation and female germline progression.
Cell lineage specification and signalling pathway use during development of the lateral plate mesoderm and forelimb mesenchyme
Summary: This study establishes a transcriptional atlas of the cell fate decisions underlying LPM specification, subdivision and development of the chicken forelimbs.
LATS1/2 control TGFB-directed epithelial-to-mesenchymal transition in the murine dorsal cranial neuroepithelium through YAP regulation
Summary: Hippo signaling kinases LATS1 and LATS2 phosphorylate downstream effectors YAP/TAZ to regulate the TGFB-induced epithelial-to-mesenchymal transition in the migratory neural crest on the dorsal cranial neural tube.
Trim33 conditions the lifespan of primitive macrophages and onset of definitive macrophage production
Summary: Yolk sac-derived macrophages of zebrafish deficient in the transcriptional regulator Trim33 (Tif1γ) have a much reduced lifespan.
PBAF chromatin remodeler complexes that mediate meiotic transitions in mouse
Summary: The ARID2 and BRG1 components of the PBAF chromatin remodeling complex fulfill essential but distinct functions during gametogenesis.
Paternally inherited H3K27me3 affects chromatin accessibility in mouse embryos produced by round spermatid injection
Highlighted Article: Histone turnover-mediated reduction of H3K27me3 during spermiogenesis is important for chromatin accessibility in early mouse embryos.
TECHNIQUES AND RESOURCES
The dynamic proteome in Arabidopsis thaliana early embryogenesis
Highlighted Article: Profiling of proteome dynamics using nanoproteomics uncovers the relationship between RNAs and proteins during Arabidopsis thaliana early embryogenesis.
Breasi-CRISPR: an efficient genome-editing method to interrogate protein localization and protein–protein interactions in the embryonic mouse cortex
Summary: A new technique combining Easi-CRISPR with in utero electroporation allows efficient and rapid visualization of endogenous proteins in embryonic brain tissue.
A scalable phenotyping approach for female floral organ development and senescence in the absence of pollination in wheat
Summary: A new automated phenotyping method for stigma and ovary development in wheat highlights the potential for genetic variation that could benefit hybrid breeding.
The Forest of Biologists
We are excited to announce the launch of The Forest of Biologists, a new biodiversity initiative created with support from the Woodland Trust, aiming to counteract nature loss and safeguard some of the most critically endangered ecosystems for future generations. Click here to see our virtual forest: For every Research Article and Review/Commentary article that is published in Development a native tree is planted in a forest in the UK.
Propose a new Workshop for 2025
Do you have an idea for a Workshop? We are now accepting proposals for our 2025 Biologists Workshops programme. As the scientific organiser, your involvement will be focused on the science. We'll take care of all the logistics. In 2025 we'll continue our efforts to diversify our Workshop programme and will be reserving one of our Workshops for an application from a Global South (GS) country to host an event overseas.
Pathway to Independence Programme - introducing our first PI Fellows
In December 2022, we announced a new programme aimed at supporting researchers as they transition from postdoc to Principal Investigator. We are delighted to announce that we have now selected our first cohort of PI fellows, meet them here.
Development Journal Meeting 2023
We are delighted to announce that our 2023 Journal Meeting ‘Unconventional and Emerging Experimental Organisms in Cell and Developmental Biology’ will be held from 17-20 September 2023 at Wotton House, Surrey, UK. Find out more and register here.
Call for papers: Metabolic and Nutritional Control of Development and Regeneration
We are welcoming submissions for our next special issue, which will focus on metabolic and nutritional control of development and regeneration. Submission deadline: 15 May 2023.
