    Segmentation of the zebrafish axial skeleton relies on notochord sheath cells and not on the segmentation clock

    Laura Lleras Forero et al.
    In contrast to amniotes, zebrafish (ray-finned fish, teleost) centra are formed from specialised notochord sheath cells, and the segmental patterning of these cells is independent of the segmentation clock.

    VEGF-C promotes the development of lymphatics in bone and bone loss

    Devon Hominick et al.
    Mice that overexpress VEGF-C in bone display a phenotype that resembles Gorham-Stout disease.

    Why plants make puzzle cells, and how their shape emerges

    Aleksandra Sapala et al.
    Puzzle-shape cells in the epidermis of many plants form due to a development constraint based on mechanical forces.

    An FGF-driven feed-forward circuit patterns the cardiopharyngeal mesoderm in space and time

    Florian Razy-Krajka et al.
    A gene network for heart versus head muscle specification has been identified in the tunicate Ciona.

    Functional divergence of paralogous transcription factors supported the evolution of biomineralization in echinoderms

    Jian Ming Khor, Charles A Ettensohn
    A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

    Single-cell transcriptome analysis of avian neural crest migration reveals signatures of invasion and molecular transitions

    Jason A Morrison et al.
    Single cell transcriptome analysis of an embryonic collective migratory cell population provides new insights into the heterogeneity of transcriptional signatures within a neural crest cell migratory stream.

    Epigenetic profiling of growth plate chondrocytes sheds insight into regulatory genetic variation influencing height

    Michael Guo et al.
    Epigenetic profiling of femoral growth plate chondrocytes helps whittle-down GWAS height variants to fewer putative functional variants.

    A minimally sufficient model for rib proximal-distal patterning based on genetic analysis and agent-based simulations

    Jennifer L Fogel et al.
    Specification and expansion during rib development is explained by Agent-Based Modeling while respecting the locality of decision-making that occurs as millions of cells coordinate their behavior to form and refine spatial pattern.

    Fibroblast growth factors (FGFs) prime the limb specific Shh enhancer for chromatin changes that balance histone acetylation mediated by E26 transformation-specific (ETS) factors

    Silvia Peluso et al.
    FGF signalling is responsible for priming the developmental enhancer ZRS across the distal limb mesenchyme during development, allowing ETS factors to modulate its activity through balancing histone acetylation.
