A method for targeted delivery of cargo to a target locus in a subject and components of the system. Generally, the method includes administering to the subject a cell that has an artificial saccharide-derived target presented on the surface of the cell, allowing the cell to localize to a target locus in the subject, then administering to the subject an agent that specifically binds to the artificial target. In some embodiments, the agent can include a therapeutic compound. In some embodiments, the agent can include a detectable label. In some of these embodiments, that method can further include detecting the detectable label.
