Negatively Charged MRI Nanoprobes for Dendritic Cell Labeling and in Vivo Tracking

摘要

Negatively charged MRI nanoprobe, PAsp-PCL/SPIO, has efficient DCs labeling capability and low cytotoxicity. DCs labeled with this probe can migrate to the draining lymph nodes from the side of injection, and this lymph node signal change was captured under MRI.
