The Effects of Placental Mesenchymal Stem Cells Labeled With Ultrasmall Superparamagnetic Iron Oxides on the Growth of Colorectal Cancer Cells.

Objective: Colorectal cancer (CRC) is one of the most common malignant tumors worldwide, with effective intervention and treatment being essential for CRC management. This study investigated the effects of human placental mesenchymal stem cells (PMSCs) labeled with ultrasmall superparamagnetic iron oxides (USPIOs) on the growth of CRC cells and the feasibility of 3.0-T magnetic resonance (MR) imaging as an in vivo tracer.
