Reconstruction of liver organoid using a bioreactor

Figure 4 Ultrastructure of sinusoidal endothelial cells. A: Scanning electron microscopic image of sinusoidal endothelial cells localized at the perfusion side. They form a thin layer (arrowhead), showing the typical appearance of a sinusoid-like vascular structure. Scale bar: 5 μm; B: Transmission electron microscopic image showing sinusoidal endothelial cell growth at the perfusion side forming a thin layer (arrowhead) overlying the A7 cells (SC). Scale bar: 1 μm; C: Transmission electron microscopic view showing tight junctions (arrow) between sinusoidal endothelial cells (EC). Scale bar: 200 nm.
