Outline of experimental design. Workflow showing detection of circulating tumor cells (CTCs) and CTC clusters (CTCcls) from patient-derived xenograft (PDX) blood using immunofluorescence staining. The reverse-phase protein array (RPPA) and transcriptomic data from PDX tumors with versus without CTCcls were interrogated and analyzed to identify differentially expressed proteins and genes.
