Abstract (original English)
Background Recently, the osteogenic potential of Adiponectin-labeled adipogenic lineage progenitors (Adipoq-lineage progenitors) in bone marrow has been observed to support bone maintenance and repair. However, little is known about the function of Schnurri-3 (SHN3, also known as HIVEP3) in other mesenchymal lineage cells, apart from its negative regulation of bone formation on osteoblasts. Method In this study, we used single-cell RNA sequencing (scRNA-seq) profiling to demonstrate that Adipoq-lineage progenitors express higher levels of Shn3 compared to other mesenchymal cell populations in mice and humans. To investigate the role of SHN3 in Adipoq-lineage progenitors, we generated a murine model specifically harboring a Shn3-deficient allele in Adipoq-expressing cells. Information of mice body weight was collected weekly to generate body weight curve. Bone phenotype was analyzed using micro-CT and histomorphometric studies. To eliminate the role of peripheral adipose tissue on bone, we collected adipose wet weight, performed intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests, and conducted a fat-transplantation study. Osteoblast and osteoclast functions were assessed through toluidine blue staining and TRAP staining, respectively. We further investigated the effect of Shn3 depletion on the differentiation of Adipoq-lineage progenitors through
