Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe collagen family of proteins represents the major structural and mecha
3、nical component of thein-vivo extracellular matrix of human tissues and organs. Type I collagen is the most abundant and assuch, it is an ideal candidate for medical materials, tissue-engineered medical products, delivery oftherapeutic cells/molecules, and in-vitro cell/tissue culture applications.
4、Furthermore, it is now evidentthat specific collagen material properties, including microstructure, mechanical integrity (stiffness),cell adhesion, and biodegradation are major determinants of the interfacial properties between cellsand collagen-based materials, including guidance of fundamental cel

Advanced understanding of collagenself-assembly, as occurs in vivo and in vitro, is contributing to a rapid expansion of commercial andlaboratory-produced collagen formulations that polymerize (self-ass

Most recent developments have focused on collagen polymer formulations withtunable features to support the rational design of collagen materials for improved tissue integration andguidance of cell fate. Unfortunately, the term “collagen” is appli

As such, the need exists for an expanded set of characteriz

T
10、his guidewill focus on the characterization of polymer forms of Type Icollagen, which is the most abundant collagen in mammalianconnective tissues and organs, including skin, bone, tendon,and blood vessels. Type I collagen may be derived from avariety of sources including, but not limited to, animal

This guide is intended to focus on purified Type Icollagen polymers as a starting material for wound andhemostatic dressings, surgical implants, substrates for tissue-engineered medical products (TEMPs), delivery vehicles forthe

Self-assembling colla-gen polymers may include, but are not limited to: (1) tissue-derived atelocollagens, monomers, and oligomers; (2) collagenproteins and peptides produced using recombinant technology;and (3) chemically synthesized collagen mimetic peptides. Its
14、hould be noted that the format of associated self-assembledcollagen-based products also will vary and may include inject-able solutions that polymerize in situ as well as preformedsheets, particles, spheres, fibers, sponges, matrices/gels,coatings, films, and other forms.
