Understanding the extracellular matrix

Tissue engineering deals with the growth and regeneration techniques of connective tissues or organs from a combination of cells and a scaffold to produce a functional organ. The engineering techniques therefore begin with an implantation of artificial materials, providing a proper environment for cells or tissues to be grown and functionalized. The scaffolds are often formulated with biodegrad...

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...

Process-induced extracellular matrix alterations affect the mechanisms of soft tissue repair and regeneration

Extracellular matrices derived from animal tissues for human tissue repairs are processed by various methods of physical, chemical, or enzymatic decellularization, viral inactivation, and terminal sterilization. The mechanisms of action in tissue repair vary among bioscaffolds and are suggested to be associated with process-induced extracellular matrix modifications. We compared three non-cross...

The matrix reorganized: extracellular matrix remodeling and integrin signaling.

Via integrins, cells can sense dimensionality and other physical and biochemical properties of the extracellular matrix (ECM). Cells respond differently to two-dimensional substrates and three-dimensional environments, activating distinct signaling pathways for each. Direct integrin signaling and indirect integrin modulation of growth factor and other intracellular signaling pathways regulate E...
