    Early anteroposterior regionalisation of human neural crest is shaped by a pro-mesodermal factor

    Antigoni Gogolou, Celine Souilhol ... Anestis Tsakiridis
    A thorough insight into the previously unrecognised role of a critical developmental regulator known as TBXT in influencing the specification of human trunk neural crest cells, the presumed precursors of the childhood tumour neuroblastoma.

    Human foveal cone photoreceptor topography and its dependence on eye length

    Yiyi Wang, Nicolas Bensaid ... Austin Roorda
    Despite evidence of retinal stretching with eye growth, cone photoreceptor sampling density in the foveal center of humans actually increases with eye length.

    Two FGFRL-Wnt circuits organize the planarian anteroposterior axis

    M Lucila Scimone, Lauren E Cote ... Peter W Reddien
    Single-cell RNA sequencing identifies an adult regional gene expression map in planarian muscle that includes two FGFRL-Wnt circuits controlling head and trunk tissue pattern.

    Wnt, Ptk7, and FGFRL expression gradients control trunk positional identity in planarian regeneration

    Rachel Lander, Christian P Petersen
    Signaling molecules expressed in overlapping body-wide transcriptional gradients determine central axis positional identity in whole-body regeneration.

    Vascular dimorphism ensured by regulated proteoglycan dynamics favors rapid umbilical artery closure at birth

    Sumeda Nandadasa, Jason M Szafron ... Suneel S Apte
    Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.

    R-spondin 3 deletion induces Erk phosphorylation to enhance Wnt signaling and promote bone formation in the appendicular skeleton

    Kenichi Nagano, Kei Yamana ... Roland Baron
    R-spondin3 global haplo-insufficiency or its deletion in pre-osteoblasts lead to gain of bone mass in the appendicular skeleton with no or opposite phenotype in the axial skeleton.

    The tumor suppressor PTPRK promotes ZNRF3 internalization and is required for Wnt inhibition in the Spemann organizer

    Ling-Shih Chang, Minseong Kim ... Christof Niehrs
    Two cancer related proteins, tyrosine phosphatase PTPRK and ubiquitin ligase ZNRF3, interact to downregulate Wnt receptors, thereby regulating Spemann organizer function during Xenopus development.

    Transcription dynamically patterns the meiotic chromosome-axis interface

    Xiaoji Sun, Lingzhi Huang ... Andreas Hochwagen
    Distributed cohesin rings flexibly tether the axial element structure of meiotic chromosomes to the underlying chromatin to readily accommodate ongoing transcription.
