    Deconstructing cold-induced brown adipocyte neogenesis in mice

    Rayanne B Burl, Elizabeth Ann Rondini ... James G Granneman
    Single-cell RNA-sequencing, spatial genomics, and histological analyses reveal that cold-induced brown adipose neogenesis is a complex adaptive response to elevated metabolic demand involving dynamic interactions between recruited immune cells and a subpopulation of poised adipocyte progenitors.

    Discovery and functional assessment of a novel adipocyte population driven by intracellular Wnt/β-catenin signaling in mammals

    Zhi Liu, Tian Chen ... YiPing Chen
    A novel population of adipocytes that play essential roles in adaptive thermogenesis via cell autonomous and non-autonomous effects and regulate systemic glucose metabolism in mice.

    Hypertrophic chondrocytes serve as a reservoir for marrow-associated skeletal stem and progenitor cells, osteoblasts, and adipocytes during skeletal development

    Jason T Long, Abigail Leinroth ... Matthew J Hilton
    Hypertrophic chondrocytes of the growth plate undergo a process of dedifferentiation to generate marrow associated skeletal stem and progenitor cells (SSPCs), which ultimately re-differentiate into cells of the osteoblast or adipocyte lineages during skeletal development.

    A bone-specific adipogenesis pathway in fat-free mice defines key origins and adaptations of bone marrow adipocytes with age and disease

    Xiao Zhang, Hero Robles ... Erica L Scheller
    A novel secondary adipogenesis pathway is defined that is unique to the bone marrow and is activated with age and in states of metabolic stress.

    OPA1 deletion in brown adipose tissue improves thermoregulation and systemic metabolism via FGF21

    Renata O Pereira, Alex Marti ... E Dale Abel
    Lack of OPA1 in BAT impairs its thermogenic activation and induces endoplasmic reticulum stress, while improving systemic metabolism and thermoregulation via ATF4-FGF21-dependent and -independent mechanisms.

    Transcriptional profiling of mouse peripheral nerves to the single-cell level to build a sciatic nerve ATlas (SNAT)

    Daniel Gerber, Jorge A Pereira ... Ueli Suter
    Establishing transcriptional profiles of nerve-inhabitant cells as resource to foster the fundamental understanding of peripheral nerves.

    Early postnatal interactions between beige adipocytes and sympathetic neurites regulate innervation of subcutaneous fat

    Jingyi Chi, Zeran Lin ... Paul Cohen
    The regulation of sympathetic innervation density by beige adipocytes in subcutaneous fat is important during a critical developmental window, but dispensable during adulthood.

    Heterogeneity of murine periosteum progenitors involved in fracture healing

    Brya G Matthews, Sanja Novak ... Ivo Kalajzic
    Murine periosteum is highly enriched for osteoprogenitors, many of which express αSMA, but fracture callus chondrocytes are partially derived from other sources.

    Estrogen exacerbates mammary involution through neutrophil-dependent and -independent mechanism

    Chew Leng Lim, Yu Zuan Or ... Valerie Chun Ling Lin
    Estrogen aggravates mammary involution through lysosome-mediated cell death, neutrophil recruitment via CXCR2 signalling, neutrophil-mediated inflammation and adipocyte repopulation.

    Dynamic control of adipose tissue development and adult tissue homeostasis by platelet-derived growth factor receptor alpha

    Sunhye Shin, Yiyu Pang ... Yuwei Jiang
    Combined fate mapping and genetic deletion studies reveal that PDGFRα+ cells and PDGFRα gene itself are required for adipose tissue development but not for adult tissue homeostasis.
