    Quantifying the Importance of Abiotic and Biotic Factors Governing the Succession of Gut Microbiota Over Shrimp Ontogeny by Wenqian Zhang, Wenqian Zhang, Zidong Zhu, Jiong Chen, Jiong Chen, Qiongfen Qiu, Jinbo Xiong, Jinbo Xiong

    Published 2021-10-01
    “…The gut microbiota tended to be governed by variable selection over shrimp ontogeny, while the rearing bacterioplankton community was shaped by homogeneous selection. …”

    Shark teeth zinc isotope values document intrapopulation foraging differences related to ontogeny and sex by Jeremy McCormack, Molly Karnes, Danielle Haulsee, Dewayne Fox, Sora L. Kim

    Published 2023-07-01
    “…Here we investigate whether dental enameloid zinc isotope (δ66Znen) values can be used to infer intrapopulation differences in foraging ecology by comparing δ66Znen with same-tooth collagen carbon and nitrogen (δ13Ccoll, δ15Ncoll) values from critically endangered sand tiger sharks (Carcharias taurus) from Delaware Bay (USA). We document ontogeny and sex-related isotopic differences indicating distinct diet and habitat use at the time of tooth formation. …”

    Characterization of gene regulatory networks underlying key properties in human hematopoietic stem cell ontogeny by Fei Li, Yanling Zhu, Tianyu Wang, Jun Tang, Yuhua Huang, Jiaming Gu, Yuchan Mai, Mingquan Wang, Zhishuai Zhang, Jiaying Ning, Baoqiang Kang, Junwei Wang, Tiancheng Zhou, Yazhou Cui, Guangjin Pan

    Published 2024-04-01
    “…The intrinsic mechanism underlying property changes in hematopoiesis ontogeny remains poorly understood. Here, we analyzed single-cell transcriptome of human primary hematopoietic stem/progenitor cells (HSPCs) at different developmental stages, including yolk-sac (YS), AGM, fetal liver (FL), umbilical cord blood (UCB) and adult peripheral blood (PB) mobilized HSPCs. …”

    A Thymic Epithelial Stem Cell Pool Persists throughout Ontogeny and Is Modulated by TGF-β by Olga Ucar, Kaiyong Li, Dmytro Dvornikov, Clemens Kreutz, Jens Timmer, Sonja Matt, Lukas Brenner, Catherine Smedley, Mark A. Travis, Thomas G. Hofmann, Ursula Klingmüller, Bruno Kyewski

    Published 2016-10-01
    “…Our findings support the model of a continuous thymic SC lineage that is maintained throughout ontogeny. TGF-β signaling differentially affects embryonic versus adult thymosphere formation, suggesting that thymic epithelial SC potency depends on both developmental stage and environmental signals. …”

    A Juvenile Specimen of the Trematopid Acheloma From Richards Spur, Oklahoma and Challenges of Trematopid Ontogeny by Bryan M. Gee, Joseph J. Bevitt, Robert R. Reisz, Robert R. Reisz

    Published 2019-03-01
    “…However, many of these shared features are likely to be influenced by ontogeny or size. The subsequent challenges that we encountered in our taxonomic referral suggest that ontogeny may be confounding taxonomy in both diagnoses and phylogenetic analyses of trematopids and emphasize the need for careful study of how this affects our understanding of trematopid intrarelationships.…”

    A new wing skeleton of the Jehol tapejarid Sinopterus and its implications for ontogeny and paleoecology of the Tapejaridae by Chang-Fu Zhou, Dongxiang Yu, Ziheng Zhu, Brian Andres

    Published 2022-06-01
    “…Here, a new wing skeleton of Sinopterus was thin-sectioned to provide the first histological data about the ontogeny of the Jehol tapejarids. Histologically, the new specimen is an immature individual at a late juvenile stage prior to sexual maturity. …”

    Coral kin aggregations exhibit mixed allogeneic reactions and enhanced fitness during early ontogeny by Chadwick Nanette E, Amar Keren-Or, Rinkevich Baruch

    Published 2008-04-01
    “…Analysis of allorecognition responses revealed an array of effector mechanisms: real tissue fusions, transitory fusions and six other histoincompatible reactions (borderline formation, sutures, overgrowth, bleaching, rejection, and partner death), disclosing unalike onsets of ontogeny and complex modes of appearance within each aggregate. …”
