The electron microscopic structure of the osteoblast

Chapter
Part of the Electron Microscopy in Biology and Medicine book series (EMBM, volume 7)

Abstract

In sections routinely stained for light microscopy, osteoblasts are most easily recognized by their strongly basophilic cytoplasm, the large Golgi apparatus in negative image, and the eccentrically located nucleus. The long axis of the cell can be both parallel and perpendicular to the surface of the bone matrix. These features are most conspicuous also in the electron microscope. In this chapter we will describe the fine structure of the nucleus and organelles, including their functions in processes such as secretion, endocytosis, etc. Where possible, it will also be described how the ultrastructure of the osteoblast is influenced by various physiological or experimental circumstances. For a review of the light microscopic structure of the osteoblast, the reader is referred to the comprehensive article of Pritchard [1].
