Expression of VLA-4, VLA-5, and LFA-1 in CD34⁺ cells during cell cycle transit.

Synchronized CD34⁺ cells were labeled with anti–VLA-4, anti–VLA-5, or anti–LFA-1 (black histograms) at indicated stages. Background staining with isotype-matched IgG is shown in white histograms. A representative experiment is depicted.
