CXCL12 Modulates Prostate Cancer Cell Adhesion by Altering the Levels or Activities of β1-Containing Integrins

Figure 5

CXCR4 and integrin β1 are located closely at focal contact sites. PC3 and DU145 cells were incubated for 2 hrs, fixed, and double-stained for CXCR4 and β1 integrin. Arrows in the images indicate the localization of both CXCR4 with β1 integrin in focal contacts.
