Figure 4

Vessel-like structure formation in 2-dimensional (2D) culture. After 3 days cultured in endothelial growth media, WJ-MSCs (a, b), HUVECs (c, d), autogenic (e, f), and allogenic (g, h) HUVECs/WJ-MSCs coculture were stained with antibodies directed against human CD31 (brown). Arrows indicated CD31 stained VLS in both of autogenic and allogenic HUVECs/WJ-MSCs coculture condition. Scale bar: 200 μm (a, c, e, and g) and 100 μm (b, d, f, and h).
