Lipophilicity Modulation of Fluorescent Probes for Imaging of Cellular Microvesicle Dynamics.

Real-time monitoring of dynamic microvesicles (MVs), vesicles associated with living cells, is of great significance in deeply understanding their origin, transport, and function. However, specific labeling MVs poses a challenge due to the lack of unique biomarkers that differentiate them from other cellular compartments. Here, we present a strategy to selectively label MVs by evaluating a series of lipid layer-sensitive cationic indolium-coumarin fluorescent probes (designated as IC-C, with ranging from 1 to 18) that feature varying aliphatic side chains (CH).
