[Osteoblasts. Morphology and biochemical activity].

Abstract

The purpose of this review is to give the latest knowledge related to the osteoblastic morphology and biochemical activity. We describe the morphological characteristics and functional features and the in vitro study models. Further on we analyze the term "characterization" of osteoblasts with special emphasis to the macromolecules synthesized by them (Type I collagen, non collagenous proteins and alkaline phosphatase). Finally we make reference to the hormones regulating the synthesis of alkaline phosphatase.
