Exempel på endoplasmic reticulum

• Although plastids remained unchanged, further development of the endoplasmic reticulum was manifested by longer profiles.

• Nuclear profiles were markedly abnormal, plasmalemma withdrawal (arrowheads) could be seen and the profiles of endoplasmic reticulum were dilated (a).

• Note the smooth and rough endoplasmic reticulum and gap junctions between theca-interna cells.

• In the cortex of the oocytes the cisternae of the endoplasmic reticulum were no longer present.

• These complexes appear occasionally to be associated with vesicles of smooth endoplasmic reticulum.

• Microtubules and the endoplasmic reticulum are highly interdependent structures.

• The tegument is a syncytial stratum, laden with membrane-bound, electron-lucid and electron-dense vesicles, mitochondria, ribosomes and smooth endoplasmic reticulum.

• One interesting protein is calreticulin, a calcium-binding protein that, in mammals, is normally located in the endoplasmic reticulum.

• Concentric-whorled membranes, having a granular appearance resembling the ribosomes of rough endoplasmic reticulum, float in the pseudocoelom between somatic muscles, reproductive tract and intestine.

• Note the granular appearance of the cytoplasm and the presence of areas of expanded granular endoplasmic reticulum (gar).

• Two layers of membrane, derived from the endoplasmic reticulum, are incorporated as internal lipid membranes.

• The rachis cytoplasm contains mitochondria, extensive rough endoplasmic reticulum, and electron-dense granules.

• The gland contains glycogen deposits, and rough endoplasmic reticulum distended into cisternae with granular material.

• The cell cytoplasm consists of few mitochondria, granules, endoplasmic reticulum, and vesicles.

• The ' factories ' of crystalline material are comprised from seemingly specialized mitochondria and rough endoplasmic reticulum elements.
