Fig. 7From: Cytoplasm protein GFAP magnetic beads construction and application as cell separation target for brain tumorsa The number of CTCs captured in CSF with the GFAP, EpCAM, and EGFR magnetic spheres. b The number of CTCs captured in the blood with the GFAP, EpCAM, and EGFR magnetic spheres. c The number of CTCs captured by GFAP magnetic spheres in different tumor stages (CSF and blood). d The number of CTCs captured by GFAP magnetic spheres at different ages (CSF and blood). The average number of CTCs is shown by the horizontal lines. e The relationship between the amount of CTCs in CSF and survival timeBack to article page
