    A neuroepithelial wave of BMP signalling drives anteroposterior specification of the tuberal hypothalamus

    Kavitha Chinnaiya, Sarah Burbridge ... Marysia Placzek
    Fate-mapping, combined with gain- and loss-of-function approaches, reveal the role of BMP signalling in the spatio-temporal development of the tuberal hypothalamus, a critically important brain region.

    Muscle contraction is required to maintain the pool of muscle progenitors via YAP and NOTCH during fetal myogenesis

    Joana Esteves de Lima, Marie-Ange Bonnin ... Delphine Duprez
    A novel mechanism links mechanical signals with the molecular YAP and NOTCH signals operating during developmental myogenesis.

    An autoregulatory cell cycle timer integrates growth and specification in chick wing digit development

    Joseph Pickering, Kavitha Chinnaiya, Matthew Towers
    A cell cycle timing mechanism similar to one operating in cultured adult oligodendrocyte progenitor cells controls the growth and patterning of the embryonic chick wing bud.

    Species-specific sensitivity to TGFβ signaling and changes to the Mmp13 promoter underlie avian jaw development and evolution

    Spenser S Smith, Daniel Chu ... Richard A Schneider
    Multiple levels of gene regulation in the TGFβ signaling pathway mediate the expression of Mmp13, establish species-specific domains of bone resorption, and likely generate evolutionary variation in jaw length.

    Genetic code expansion, click chemistry, and light-activated PI3K reveal details of membrane protein trafficking downstream of receptor tyrosine kinases

    Duk-Su Koh, Anastasiia Stratiievska ... Sharona E Gordon
    The generation of phosphoinositide 3,4,5-trisphosphate causes an increase in the number of TRPV1 ion channels and insulin receptors in the plasma membrane.

    Visually induced changes in cytokine production in the chick choroid

    Jody A Summers, Elizabeth Martinez
    IL-6 gene and protein expression are rapidly and transiently upregulated in the choroid in response to myopic defocus, as a result of prior form deprivation or treatment with +15 D lenses in a nitric oxide-dependent manner.

    Bimodal function of chromatin remodeler Hmga1 in neural crest induction and Wnt-dependent emigration

    Shashank Gandhi, Erica J Hutchins ... Marianne E Bronner
    Chromatin remodeler Hmga1 has two separable functions in neural crest development, first neural crest specification at the neural plate border and later in Wnt-dependent emigration from the neural tube.

    scRNA-sequencing in chick suggests a probabilistic model for cell fate allocation at the neural plate border

    Alexandre P Thiery, Ailin Leticia Buzzi ... Andrea Streit
    Neural plate border cells co-express neural, neural crest, and placodal transcriptional programs before cell fate decisions occur and are transcriptionally heterogeneous along the antero-posterior and medial-lateral axis.

    Essential metabolism for a minimal cell

    Marian Breuer, Tyler M Earnest ... Zaida Luthey-Schulten
    A near-complete flux balance analysis model of a minimal cell demonstrates the high essentiality of its metabolic genes, agrees well with experimental essentiality data and suggests some further gene removals.

    Probe-Seq enables transcriptional profiling of specific cell types from heterogeneous tissue by RNA-based isolation

    Ryoji Amamoto, Mauricio D Garcia ... Constance L Cepko
    Probe-Seq is a cell type specific bulk RNA sequencing method that can be applied to a wide-ranging tissue types from both vertebrates and invertebrates without genetic labeling.
