Fundamentals of Extracellular Matrix Biomaterial Assimilation

Biaxial mechanical evaluation of cholecyst-derived extracellular matrix: a weakly anisotropic potential tissue engineered biomaterial.

A new acellular, natural, biodegradable matrix has been discovered in the cholecyst-derived extracellular matrix (CEM). This matrix is rich in collagen and contains several other macromolecules useful in tissue remodeling. In this study, the principal material axes, collagen fiber orientations, and biaxial mechanical properties in a physiological loading regime were characterized. Fiber directi...

Bone marrow derived cell-seeded extracellular matrix: A novel biomaterial in the field of wound management

Aim: Extensive or irreversible damage to the skin often requires additional skin substitutes for reconstruction. Biomaterials have become critical components in the development of effective new medical therapies for wound care. Materials and Methods: In the present study, a cell matrix construct (bone marrow-derived cells (BMdc) seeded extracellular matrix [ECM]) was used as a biological substi...

Functionalization of biomaterial surfaces using artificial extracellular matrices

Construction of biomaterials with the ability to guide cell function is a topic of high interest in biomaterial development. One approach is using components native to the ECM of the target tissue to generate in vitro a microenvironment that can also elicit specific responses in cells and tissues--an artificial ECM (aECM). The focus is on collagen as the basic material, which can be modified us...

Extracellular Matrix

The tissues of a multicellular organism contain two main components, the cells themselves, onwhichmost biological research has traditionally focused, and the material that lies between the cells. This material is called the extracellular matrix, usually abbreviated to ‘ECM’. The ratio of tissue volume occupied by ECM to that occupied by cells varies from less than 1:10 (e.g. in muscles) to more...
