Summary: This Primer introduces micropatterning as a tool to study development and discusses what we have learnt so far with this technique.
Summary: This Review discusses how sharp patterns of segments and boundaries are formed during hindbrain development.
Single-cell transcriptome profiling of the human developing spinal cord reveals a conserved genetic programme with human-specific features
Summary: Single-cell transcriptome analysis of the neural tube of human embryos from gestational weeks 4-7 provides insight into the molecular complexity and cellular diversity of the developing human spinal cord.
Summary: Analysis of the genome-wide distribution of H4K20me3 in human spermatozoa, including H4K20me3-free nucleosomes, demonstrates a potential dual purpose of paternally transmitted histones: regulation of heterochromatin and guidance towards euchromatin transcription.
STEM CELLS AND REGENERATION
Highlighted Article: During development, the first B lymphocytes are produced in the absence of Notch signaling and, thus, independently from HSCs.
The exocyst complex regulates C. elegans germline stem cell proliferation by controlling membrane Notch levels
Summary: The conserved exocyst complex controls Notch receptor levels on the niche-interacting membrane of Caenorhabditis elegans germline stem cells to regulate their proliferation and maintain fertility.
osr1 couples intermediate mesoderm cell fate with temporal dynamics of vessel progenitor cell differentiation
Summary: Analysis of the osr1 mutant phenotype reveals roles in determining the extent of intermediate mesoderm formation while inhibiting premature differentiation of neighboring vessel progenitors.
Summary:In vivo analysis of rasip1 mutants reveals multiple roles for Rasip1 during angiogenic sprouting, anastomosis and lumen formation, including stabilization of tricellular junctions to permit coordinated cell rearrangements and multicellular tube formation.
Sequestration to lipid droplets promotes histone availability by preventing turnover of excess histones
Highlighted Article: During Drosophila oogenesis, lipid droplets promote the intercellular transport of the histone anchor Jabba to the oocyte, where it prevents histone degradation.
The atypical RNA-binding protein Taf15 regulates dorsoanterior neural development through diverse mechanisms in Xenopus tropicalis
Summary: Taf15 has an integral and pleiotropic role in the development of dorsoanterior neural tissues via gene regulation that is target and co-factor dependent, subject to the myriad factors present at different stages of development.
STAU2 binds a complex RNA cargo that changes temporally with production of diverse intermediate progenitor cells during mouse corticogenesis
Summary: The double-stranded RNA-binding protein STAU2 associates dynamically with RNA determinants that contribute to intermediate progenitor cell diversity and cortical lamination during mouse cerebral cortex development.
A polarized nucleus-cytoskeleton-ECM connection in migrating cardioblasts controls heart tube formation in Drosophila
Summary: CAP and MSP300 are involved in connecting the nucleus and extracellular matrix during heart formation, which leads to the maintenance of post-mitotic Tinman-positive cardioblasts.
Highlighted Article:Drosophila Arc1 exhibits microbiota-dependent, tissue-specific differential expression and functionally interacts with a key Acetobacter sp. isolate to regulate developmental growth and metabolic traits.
Highlighted Article: A zebrafish forward genetic screen identifies a switch-like regulator of growth and regeneration, which suggests that direct suppression of rRNA transcription may constitute an evolutionarily conserved ‘pause button’ for organismic growth.
The pioneer transcription factors Foxa1 and Foxa2 regulate alternative RNA splicing during thymocyte positive selection
Highlighted Article: The pioneer transcription factors Foxa1 and Foxa2 are required for positive selection during T-cell development in the thymus for regulation of RNA splicing.
