Integrin β1 chain expression is lower in BM-MSC cultures containing cell aggregates. Integrin α5 (a) chain and β1 (b) chain expression was analyzed in clustered Eph/Ephrin-Fc treated cultures that formed or did not form cell aggregates. There are no significant differences in the percentages of α5⁺ cells at any time point, but the values of β1⁺ cells are significantly lower at 3 and 6 days in cultures containing cell aggregates than in those without them. Data were obtained from five different donors. **p ≤ 0.01, ***p ≤ 0.005, versus respective control
