Figure 209 from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Portions of two hepatic cells and the intervening bile canaliculus from rat liver. Two stacks of Golgi ciste...

This image shows a group of secretory vesicles loaded with very low density lipoproteins located near the sinusoidal cell membrane of a hepatocyte. The fate of these VLDLs is to be secreted into the b...
