Figure 5. Stabilization of the vascular network by mesenchymal stem cells.
Live/dead fluorescent staining of the HUVEC channel (right panels) and the MSC channel (left panels) after two weeks of culture. The images demonstrate cell organization in co-cultures of HUVECs and mesenchymal cells from various sources (UCV, UCA, bone marrow MSC). Stabilized vascular network is seen in the co-culture of HUVECs with MSCs, but not with UCV and UCA cells. Fluorescent microscopy, scale bar 500 μm.
