Oscillatory Hedgehog signaling and temporal coordination of atonal dynamics at the eye differentiation front in Drosophila

This study reveals that oscillatory Hedgehog signaling, generated through a feedback loop involving the periodic expression of its receptor Patched, provides a temporal cue that synchronizes the pulsatile expression of the proneural gene *atonal* to ensure coordinated pattern formation along the differentiation front of the developing *Drosophila* eye.

Single-cell chromatin profiling reveals dynamic regulatory logic and enhancer elements in brain and retina development

This study constructs a temporally resolved single-cell chromatin accessibility atlas of zebrafish brain and retina development to map dynamic regulatory landscapes, link transcription factor activity to cell identity, and functionally validate conserved enhancer modules that orchestrate neural gene expression.

Temporal Notch signaling and Hes-mediated competitive de-repression regulate mucociliary cell fates in Xenopus

This study reveals that temporal Notch signaling and a mechanism termed "competitive de-repression," involving sequentially expressed Hes factors and Spdef-mediated regulation, orchestrate the specification of multiple mucociliary cell fates in Xenopus, thereby extending the traditional lateral inhibition paradigm to explain the generation of diverse cell types.

Temporal and Notch identity determine neuropil targeting depth and synapse location in the fly visual system

This study demonstrates that the temporal identity and Notch signaling status of Drosophila medulla neurons genetically determine their specific neuropil targeting depth and synapse location in the adult brain, thereby linking developmental patterning mechanisms directly to the functional architecture of visual circuits.

Laminin and Fibronectin Cooperate to Guide Endothelial Self-Organization During Intersegmental Vessel Formation

This study demonstrates that laminin and fibronectin in the extracellular matrix cooperate with chemical guidance cues to mechanically confine and guide the self-organization of endothelial cells during zebrafish intersegmental vessel formation, as revealed by combined in vivo imaging and hybrid mathematical modeling.

Male mice heterozygous for Protamine-1 and Protamine-2 are infertile displaying sperm damage and retention of Protamine-2 precursors, transition proteins and histones.

Male mice heterozygous for both Protamine-1 and Protamine-2 are infertile due to sperm DNA damage, impaired hypercondensation, and the retention of precursor proteins, despite having a normal mature protamine ratio, indicating that infertility in this context is better detected by assessing protamination levels and precursor retention rather than the final protamine ratio.

Goofy/123Cre Lineage Tracing Differentiates Olfactory and Vomeronasal Neurons from GnRH-1 and Terminal Nerve Neurons During Neuronal Migration and Reveals Additional Olfactory Placode-Derived Cells in the Brain

This study utilizes Goofy/123Cre lineage tracing to demonstrate that while Goofy broadly marks nasal chemosensory neurons and terminal nerve cells, it is absent in migrating GnRH-1 neurons, yet later reveals a distinct population of Goofy-expressing basal forebrain neurons with nasal origins, thereby clarifying the genetic heterogeneity and developmental trajectories of olfactory placode-derived cells.

Resolving thyroid lineage cell trajectories merging into a dual endocrine gland in mammals

By leveraging a single-cell transcriptome atlas of mouse pharyngeal endoderm, this study elucidates the gene regulatory networks and spatiotemporal mechanisms—specifically a partial epithelial-mesenchymal transition—that enable the merging of endoderm-derived thyroid and ultimobranchial progenitors into a dual endocrine gland, while revealing how mixed-type thyroid carcinoma recapitulates this developmental trajectory to drive invasive behavior.

Med12 and Med13 prevent tumorigenic dedifferentiation of intermediate neural progenitors and premature loss of neural stem cells

This study reveals that in the developing *Drosophila* brain, Med12 and Med13 prevent tumorigenic dedifferentiation of intermediate neural progenitors and maintain neural stem cell self-renewal by differentially coordinating with or antagonizing specific subsets of core mediator complex subunits to regulate fate commitment and stemness.

Drosophila germ band extension: a two-state reshaping mechanism

This paper reveals that *Drosophila* germ-band extension employs a two-state remodeling strategy where the anterior tissue behaves as a fluidized state driven by internal myosin fluctuations, while the posterior tissue acts as a solid undergoing crystal-like ordering and plastic flow induced by external stresses, collectively solving the inhomogeneous reshaping challenge of embryogenesis.
