    Tsc2 disruption in mesenchymal progenitors results in tumors with vascular anomalies overexpressing Lgals3

    Peter J Klover, Rajesh L Thangapazham ... Thomas N Darling
    Tsc2 inactivation in mouse mesenchymal progenitors produced tumors with vascular anomalies reminiscent of human angiomyolipomas, and a gene expression signature in Tsc2-deficient tissues which included Lgals3, as a novel potential biomarker for TSC1/2 loss.

    Complement 3a receptor 1 on macrophages and Kupffer cells is not required for the pathogenesis of metabolic dysfunction-associated steatotic liver disease

    Edwin A Homan, Ankit Gilani ... James C Lo
    Ablation of the G-protein-coupled receptor C3aR1 specifically on macrophages or Kupffer cells does not alter the course of metabolic dysfunction-associated steatotic liver disease in a dietary mouse model.

    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.
