• Three-dimensional folding dynamics of the Xenopus tropicalis genome

    Animal interphase chromosomes are organized into topologically associating domains (TADs). Niu et al. show that X. tropicalis is a powerful model for chromosome architecture analysis suggesting that chromatin remodeling plays an essential role in de novo TAD establishment. Published in Nature Genetics.

  • The Scf/Kit pathway implements self-organised epithelial patterning

    Social distancing is no mystery to Xenopus cells! Chuyen et al. report how thousands of multiciliated cells distribute into a regular pattern in the developing epidermis, through homotypic repulsion and homing at intercalation sites. Published in Developmental Cell.

  • Biallelic variants in COPB1 cause a novel, severe intellectual disability syndrome with cataracts and variable microcephaly

    CRISPR/Cas9-mediated mutation of Coat protein complex 1 (COPI) subunit COPB1 in X. tropicalis recapitulates features of the human "coatopathy" syndrome including microcephaly and cataracts. Published in Genome Medicine.

  • Chromatin accessibility and transcription factor activity (during gastrulation)

    Single‐cell chromatin‐accessibility and transcriptomic analyses identify the contribution and cooperation of key transcription factors in zygotic gene expression. Transcriptional heterogeneity at the gastrula stage of vertebrate embryogenesis is involved in mesoderm induction, dorsal‐ventral patterning, and establishment of the dorsal axis. Bright et al. published in EMBO J.
