Abstract:
The extracellular matrix is mimicked by a novel dendrimer-based hydrogel, which exhibits a highly interconnected porous network, enhanced mechanical stiffness, and a low swelling ratio. The hydrogel system supports the proliferation and differentiation of mesenchymal stem cells without any cytotoxic effects. This dendrimer-based hydrogel may serve as a model for developing new advanced materials with applications in tissue engineering.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
