Fig 4. Relationship between tumor phenotypes and CXCR4 or CXCR7 expression in GC cell lines.

(A) RT-PCR of CXCR4 and CXCR7 in 6 diffuse-type GC derived cell lines. (B) Macroscopic findings of bloody ascites and multiple tumor nodules (arrowhead or dotted circle) in SCID/SCID mice formed within 3 weeks after inoculation of each cell line.
