<p>(A and B) MMD ECFCs (green colored) make fewer tubes per unit area than normal ECFCs (n = 6, 11.9 ± 4.0% of control; p<0.001). MMD SPCs (red colored) also make less number of tubes (n = 6, 51.8 ± 21.5% of control; p<0.001). (C) The tube walls made by MMD ECFCs are thinner (n = 5, 14.4% of control; p< 0.001), but the tube walls composed of MMD SPCs are thicker than those of controls (n = 5, 763.4% of control; p<0.001) (*p<0.05, **p<0.01, ***p<0.001).</p
