Fig. 6. hicctron microifraph ui section ol rat liver. Shows hKiod sinusoid {.<); a |iortion of 

 a lining cell (/), probably a Kupffcr cell; antl numerous extensions of the parenchymatous 

 cells into microvilli exposed to the sinusoid (space of Disse). Some of the microvilli (w) show 

 linearly-arranged granules, producing an apparent cross-striation. Within the parenchymatous 

 cells, note the vacuoles (r), dark mitochondria, and the ribonucleoprotein granules of the 

 ergastopiasm. X 10,500. 



Fig. 7. Electron micrograph of rat liver. [From (52). | Shows microvilli extending into bile 

 canaliculus (hr), pcribiliary 'dense bodies' (dh), and (Jolgi appaiatus (g). )< 14,400.
