Incubating HUVEC with Vi for 24 h did not affect the BrdU-positive cell rate. Integrin alpha5 beta1 antibody was added to HUVEC before incubation with Vi. (A) BrdU-positive cells were identified by immunohistochemistry (red). Nuclei are stained blue. Scale bar indicates 100 µm. (B) Vi did not affect the BrdU-positive cell rate in this experimental condition. Data represent mean ± s.d. of 3 independent experiments.
