Study progress in biological functions of Periostin in bone mineralization / 国际生物医学工程杂志

ABSTRACT

Periostin is a matri-cellular protein which was originally identified in MC3T3-E 1 osteoblast-like cell line,expressing in multiple tissues like bones,teeth,skin and cardiac valves.Periostin is also found in a large variety of cancers and injured tissues,involving in cancer cell invasion and metastasis as well as wound repair.Recent studies have suggested the role of Periostin in osteoblast adhesion and differentiation,fibrillogenesis,mineralization and bone fracture healing,and its expression is regulated by mechanical stress,various transcription factors,hormones and growth factors.In this article,we will discuss the expression,localization and general characteristics of Periostin,and provide a review on the study of it in bone biology.
