The Effect of Pulsatile Flow on bMSC-Derived Endothelial-Like Cells in a Small-Sized Artificial Vessel Made by 3-Dimensional Bioprinting

Figure 4

Endothelial-like cell tube formation assay. The chondrocytes after 6 hours (a) and 12 hours (d), the bMSCs after 6 hours (b) and 12 hours (e), and the endothelial-like cells after 6 hours (c) and 12 hours (f). There are tube formations at endothelial-like cells after 12 hours (f). The scale bar indicates 500 μm.
