Adhesion and migration of synchronized CD34⁺ cells on VCAM-1 and ICAM-1.

(A) Adhesion to plates adsorbed with VCAM-1 (n = 6), ICAM-1 (n = 3), or BSA (n = 3) was determined in synchronized CD34⁺ cells at indicated stages of the cell cycle. (B) Transmigration across VCAM-1 was assessed toward MS-5 CM (●) and nonconditioned medium (○; n = 3). (C) Transmigration across ICAM-1 was measured toward MS-5 CM (●) and control medium (○) (n = 3). *P < .05 compared with G₀/G₁ CD34⁺cells.
