3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence
Advanced Healthcare Materials, EarlyView.Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.
