Abstract

Reconciliation of the evolving interplay between organic moieties and inorganic crystals lies at the heart of modern biomineralization inquiry. Recent biomineralization research in vertebrates has identified, characterized and described functions for key noncollagenous extracellular matrix proteins regulating crystal growth in the skeleton and dentition by binding to mineral. Gene mutations affecting mineral-regulating proteins typically lead to bone and tooth nanocrystallites defective in number, size, shape and/or orientation, and can even potentially lead to changes in mineral type, such that these otherwise hard tissues become diseased, soft and/or brittle. Several bone and tooth diseases will be discussed in terms of altered molecular determinants of mineralization, with also some discussion of these factors in soft tissues undergoing pathologic calcification (like blood vessels).
