Adhesion assay of MO- and MOSN-MSCs cells over collagen I (Col I), collagen IV (Col IV), fibronectin (FN), vitronectin (VN), Matrigel, and fetal bovine serum (FBS). Columns represent the average of 4 samples tested (each sample both MO- and MOSN-MSCs). MO-MSCs present a more pronounced adhesive response toward extracellular matrix (Mann-Whitney; ***P<0.001).
