Review the following terms before working on the problem: cytoskeleton, cell culture, fibroblast, electron microscopy
The cytoskeleton of cultured hamster kidney cells was studied in this experiment. A microscopic section, cut longitudinally through a cell process of a fibroblast, was processed for transmission electron microscopy.
1. What elements of the cytoskeleton are labeled by A, B and C?
2. Name the main protein components of these filaments.
3. What other components can be recognized in the micrograph?
