At the same time, the influence of internalized NPs on SCs properties, namely, their homing, migration ability, and functioning, remains scarcely investigated. Here, H1 human embryonic stem cells (hESCs) labeled with visible (Vis) and near-infrared (NIR) fluorescent NPs are studied in vitro, focusing on the NPs internalization and release efficiency, cytocompatibility, intracellular distribution, as well as the migration ability of hESCs carrying NPs.
