Figure Lengend Snippet: Semi-quantitative RT-PCR analysis showing the total VWF mRNA expression in co-colonized HUVECs and HUASMCs. RNA of both cell types was isolated separately. The expression of VWF in 0.1 N/m 2 stimulated HUVECs was taken as reference. ( A ) MALDI mass spectrum from supernatants of the “ artificial artery” after each day. Randomly selected peptides show constant molecular mass-signal intensities over a period of five days (abscissa: relative molecular mass m/z, z = 1; ordinate: relative intensity, arbitrary units). ( B ) MALDI mass spectrum of the supernatant of endothelial cells after stimulation with 3.0 N/m 2 (upper spectrum) and without stimulation (0.1 N/m 2 ) (lower spectrum) (abscissa: relative molecular mass, m/z, z = 1; ordinate: relative intensity, arbitrary units). ( C ) Relative mass-signal intensities of Up 4 A in secretomes isolated from HUVECs, HUASMCs, and HUVEC/HUASMC co-cultures in the “ artificial artery ” after stimulating with 3 N/m 2 for five days. ( D ) Semi-quantitative RT-PCR analyses showing the total mRNA expression of KLF2, TIMP1, and CCND1 in co-colonized HUVECs exposed to 3 N/m 2 for five days. The expression of each gene in 0.1 N/m 2 stimulated HUVECs was taken as reference. ( E ) Semi-quantitative RT-PCR analysis showing the total EDN1 mRNA expression in co-colonized HUVECs (0.1 N/m 2 vs. 3 N/m 2 ) and HUASMCs (0.1 N/m 2 vs. 3 N/m 2 ). The expression of END1 in 0.1 N/m 2 stimulated HUVECs was taken as reference.
