Efferocytosis‐Driven Polyamine Metabolism in Macrophages Enhances Cancer Stem Cell Enrichment after Chemotherapy in Ovarian Cancer

Advanced Science, EarlyView.
Chemotherapy‐induced efferocytosis drives ovarian cancer stem cell enrichment. By engulfing apoptotic cancer cells, macrophages upregulate ODC1 and produce putrescine, which elevates osteopontin (OPN) expression. Secreted OPN then activates the CD44 receptor on cancer cells, promoting stemness and chemoresistance.
