Patients face a serious threat if solid tumor leaves behind partial residuals or cannot be completely removed after surgical resection. Immunotherapy has attracted attention as method to prevent this condition. However, the conventional immunotherapy targeting tumors, that is, intravenous injection, limitations in homing on and vivo expansion not shown effective clinical results. To overcome these limitations, NK cells (Natural killer cells) were encapsulated micro/macropore-forming...
