    Mutation analysis links angioimmunoblastic T-cell lymphoma to clonal hematopoiesis and smoking

    Shuhua Cheng, Wei Zhang ... Wayne Tam
    Comparative analysis establishes genetic links among angioimmunoblastic T-cell lymphoma (AITL), clonal hematopoiesis, and concomitant hematologic malignancies, and provides insights into the cell of origin, etiology, and biomarker discovery for AITL.

    Memory persistence and differentiation into antibody-secreting cells accompanied by positive selection in longitudinal BCR repertoires

    Artem Mikelov, Evgeniia I Alekseeva ... Ivan V Zvyagin
    High degree of clonal persistence and excess of inter-individual convergence are observed in human memory B cell repertoires, along with signatures of both negative and positive selection in most abundant clonal lineages.

    Clonal transcriptomics identifies mechanisms of chemoresistance and empowers rational design of combination therapies

    Sophia A Wild, Ian G Cannell ... Kirsty Sawicka
    Lineage resolved single-cell RNA-seq of mammary carcinoma models uncovers a metabolic vulnerability of taxane-resistant clones.

    The follicle epithelium in the Drosophila ovary is maintained by a small number of stem cells

    Jocelyne Fadiga, Todd G Nystul
    Just 2-4 follicle stem cells maintain each follicle epithelium in the Drosophila ovary, and they reside within a single ring at the anterior edge of the tissue.

    Evaluation of clonal hematopoiesis and mosaic loss of Y chromosome in cardiovascular risk: An analysis in prospective studies

    Sami Fawaz, Severine Marti ... Thierry Couffinhal
    If CHIP and mLOY do not significantly contribute to inflammation, atherosclerosis or myocardial infarction risk independently, CHIP may increase the risk of MI in men who do not carry mLOY.

    Epigenetically distinct synaptic architecture in clonal compartments in the teleostean dorsal pallium

    Yasuko Isoe, Ryohei Nakamura ... Hiroyuki Takeda
    The dorsal telencephalon (pallium) in medaka fish accommodates an epigenetically distinct brain area that selectively regulates unique set of synaptic genes compared to the surrounding pallial region, providing insights into the evolution of the pallium in vertebrate.

    Retinal stem cells modulate proliferative parameters to coordinate post-embryonic morphogenesis in the eye of fish

    Erika Tsingos, Burkhard Höckendorf ... Joachim Wittbrodt
    3D niche topology imposes a spatially biased random stem cell loss, which is differentially fine-tuned in neural retina and retinal pigmented epithelium to regulate growth, shape, and cellular topology.

    Gallbladder adenocarcinomas undergo subclonal diversification and selection from precancerous lesions to metastatic tumors

    Minsu Kang, Hee Young Na ... Jong Seok Lee
    As the first to track clonal evolution from precancerous to metastatic lesions in gallbladder cancer patients, spatial and temporal analyses reveal how subclonal diversity in precancerous stage changes toward the metastasis, which help early detection and effective treatment of cancer.

    Early life imprints the hierarchy of T cell clone sizes

    Mario U Gaimann, Maximilian Nguyen ... Andreas Mayer
    The rapid development of immune memory in infancy shapes the composition of T cell defenses throughout the human lifespan.

    Whole genome phylogenies reflect the distributions of recombination rates for many bacterial species

    Thomas Sakoparnig, Chris Field, Erik van Nimwegen
    For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.
