Endosteal Integrin-α8^⁺ Mesenchymal Stem Cells Maintain Hematopoietic Stem Cell Function via Extracellular Matrix-Mediated Interactions

Scientists identified a distinct subset of MSCs expressing integrin α8 within the bone marrow endosteum. These cells exhibited distinct MSC properties and higher hematopoietic supportive activity than other MSC subsets.
