Bifurcate Regulation of Hematopoietic Homeostasis and Bone Osteogenesis by VHL‐HIF2α‐Controlled Adipocyte Function

Advanced Science, EarlyView.
The VHL‐HIF2α (VHL is Von Hippel‐Lindau) axis in adipocytes differentially regulates hematopoiesis and bone formation through stem cell factor (SCF) and chemerin, respectively. This hypoxia‐responsive pathway in adipocytes establishes a systemic signaling network with HSCs and MSCs to maintain tissue homeostasis, revealing a targetable axis for ...

Mapping the Tissue‐of‐Origins of Mesenchymal Stromal Cells in Injury Repair

Advanced Science, EarlyView.
This study maps mesenchymal stromal cells (MSCs) across multiple tissues, revealing that bone marrow–derived MSCs mobilize monocytes via CCL2 to promote systemic inflammation but do not migrate to distant organs to form fibrotic or tumor stroma. Instead, local MSCs dominate tissue remodeling, suggesting a “two‐hit” model linking systemic inflammation ...

Steap4 Promotes Senile Osteoporosis via Fe2+‐ROS/C/EBPβ Feedback‐Driven Ferroptosis and Adipogenesis in Senescent BMSCs

Advanced Science, EarlyView.
Senescent bone marrow mesenchymal stem cells (BMSCs) exhibit increased sensitivity to ferroptosis, a phenomenon associated with Steap4, a nicotinamide adenine dinucleotide phosphate hydrogen (NADPH)‐dependent metalloreductase that reduces Fe3+ to Fe2+.
