Mechanistic Insights into Bioprosthetic Heart Valve Calcification and Anti-Calcification Strategies
Reviews in Cardiovascular MedicineProsthetic heart valves are crucial for treating valvular heart disease and serve as substitutes for native valves. Bioprosthetic heart valves (BHVs) are currently the most common type used in clinical practice.

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,

Engineering Extracellular Microenvironments: The Impact of Fibrous Materials on Cell Behavior
Advanced Healthcare Materials, EarlyView.Fibrous structures are key elements of the native extracellular matrix and crucial for directing cell behavior. This review discusses how fiber properties such as composition, diameter, and alignment affect cell responses in 2D and 3D systems. Strategies for integrating fibrous cues into engineered tissues are highlighted, and future directions for ...
