Excerpt
The liver harbors a specialized capillary bed. It is characterized by Lyve-1 and VEGFR3 expression, low CD31 and vWF expression and lack of CD34 expression [
1], Moreover, the basement membrane is discontinuous, and liver sinusoidal endothelial cells are adjacent to a discontinuous basement membrane. Finally, the blood flow through liver sinusoidal capillaries is slow compared to many other organs. Besides the role of hepatic capillary beds in exchange of substances and gases between liver and blood, the endothelium of the liver is required for both liver development [

3] and liver regeneration [
4]. Interestingly, liver regeneration seems to be similar to liver development in that endothelial signals seem to be required during both processes. In the regenerating liver, it was shown that so-called angiocrine signals are needed and involved in discriminating between liver regeneration and liver fibrosis [
