Abstract Background Numerous studies in rats and a few other mammalian species including man have shown that the sinusoidal cells constitute an important part of liver function. In the pig however which is frequently used in studies on liver transplantation and liver failure models our knowledge about the function of hepatic sinusoidal cells is scarce. We have explored the scavenger function of pig liver sinusoidal endothelial cells LSEC a cell type that in other mammals performs vital elimination of an array of waste macromolecules from the circulation. Results 125I-macromolecules known to be cleared in the rat via the scavenger and mannose receptors were rapidly removed from the pig circulation 50 of the injected dose being .
