Native Collagen

Native collagen is the naturally organized, triple-helical form of collagen, a structural protein that provides tensile support and cell-interactive cues in tissues. In bioengineering, preserving this molecular architecture helps retain fibril formation, integrin recognition, and biological activity that can be reduced when collagen is denatured into gelatin. Under physiological conditions, collagen molecules assemble into fibrils and can be stabilized through controlled crosslinking, producing hydrated networks or scaffolds with tunable mechanical properties. These materials support cell adhesion and growth in tissue engineering, wound repair, drug delivery, and three-dimensional culture, while native structure provides a platform for designing biomaterials that better mimic extracellular matrix environments.

2012

Simple and reproducible procedures are described for making three structurally distinct collagen assemblies from a common commercially available Type I collagen monomer. Native type, fibrous long spacing or segmental long spacing collagen can be constructed by varying the conditions to which the 300 nm long and 1.4 nm diameter monomer building block is exposed.
