We observed a significant increase of Col1a1 and CCL2 expression induced by MPs from SSc patients compared to HD (median of 1.55 vs. 1.06 for Col1a1, respectively, p<0.05, Figure 3E, and median of 1.21 vs. 0.98, for CCL2, respectively, p<0.05, Figure 3H), and a trend toward for the increased of Col1a2 expression induced by MPs from SSc patients compared to HD (median of 2.05 vs. 0.935, respectively, p=0.1, Figure 3F). The gene discussed is CCL2; the disease is systemic sclerosis.
