Cell Calcification Models and Their Implications for Medicine and Biomaterial Research
Advanced Healthcare Materials, EarlyView.Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,
