List of the identified proteins with differential expression in P7 by comparison with P3.

<p>Ratio values (fold change) of normalized protein spots intensities, in 2-DE gels, obtained from cells recovered from both passage 3 and passage 7 (P7/P3) after <i>ex-vivo</i> expansion, as described in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043523#s4" target="_blank">Material and Methods</a> section.</p>a<p>Estimated MW (kDa).</p>b<p>Theoretical p<i>I.</i></p>c<p>Values of 0.05 or less to ensure high statistical confidence of differential expression. In some specific cases, results with ANOVA <i>p</i> values up to 0.05 (underlined) are shown.
