VIM and gastric cancer: Figure 6 shows the flow cytometric analysis of m-PBMCs from a stage IV gastric cancer patient. The m-PBMCs from this patient were divided into four vials, with the analysis of one vial shown in Figure 6. Sorting was performed to separate the CD45+Vimentin- fraction (normal hematopoietic fraction), consisting of normal hematopoietic cells, and the CD45-Vimentin+ fraction (CTC fraction), mainly composed of CTCs.
