Prior studies have suggested the possibility of immune-mediated death of xenogeneic hepatocytes in a bioartificial liver (BAL) during hemoperfusion. This study was designed to elucidate how immunity may cause death of xenogeneic hepatocytes in the BAL. Healthy dogs were treated with a BAL containing hollow fiber membranes with large pores (200 nm) or small pores (400 kDa). https://ashleyshomestores.shop/product-category/twin-coverlet-set/
