Impaired comitogenic effects of solid phase-immobilized fibronectin (FN), anti-CD29 MoAb (4B4), or anti-CD49d MoAb (3G6) on CD3-dependent T-cell proliferation after allo-BMT. Purified lymphocytes obtained from patients after T-cell–depleted allo-BMT (<4 mo, n = 4; 4-12 mo, n = 5; <12 mo, n = 5), and healthy volunteers (n = 20) were stimulated in a serum-free medium by immobilized anti-CD3 MoAb (0.1 μg/mL) with FN (5 μg/mL) or MoAbs (5 μg/mL) against CD2, CD29, and CD49d. After 3-day culture, proliferative response was assessed by [3H]thymidine incorporation. Results are expressed as the mean cpm of triplicate samples and SEM.
