Expression of adhesion molecules after LPS stimulation.

<p>MSCs were left untreated or were stimulated with LPS [10 ng/ml]. Flow cytometry data are presented as ΔMedian of 5–7 independent experiments (bmMSCs, n = 5; pgMSCs, n = 7). (A) Absolute fluorescence intensity is shown. (B) Relative induction of fluorescence intensity with untreated MSCs set as 1 (reference value) is shown for visualization of LPS-induced up-regulation; Mann-Whitney U test was used for statistical analysis; significance was set at the level of <i>P</i>≤0.05.
