제목 Anti-Senescence Ion-Delivering Nanocarrier for Recovering Therapeutic Properties of Long-Term-Cultured Human Adipose-Derived Stem Cells
초록 The stemness and therapeutic functions of adipose-derived stem cells (ADSCs) decrease on long-term cell culture. To utilize long-term-cultured ADSCs (L-ADSCs), we designed a novel anti-senescence ion-delivering nanocarrier (AIN). We introduced to L-ADSCs AIN for delivering transition metal ions in an intracellular manner through endocytosis that can enhance angiogenic paracrine factor secretion. The low pH condition in the endosomes induced the release of transition metal ions in the L-ADSCs, which in turn caused a mild elevation in the levels of reactive oxygen species (ROS). The elevated mild ROS induced downregulation of senescence-related gene expression, whereas upregulation of stemness-related gene expression and angiogenic paracrine factor.
