About the Edition

A polymeric scaffold was synthesized and chemically modified with bioactive peptides to promote neuron cell adhesion and guide neurite outgrowth for neural tissue engineering applications. Specifically, 2-hydroxyethyl methacrylate (HEMA) and 2-aminoethyl methacrylate (AEMA) monomers were co-polymerized to form a transparent hydrogel within which well defined channels were introduced using a fiber templating technique. P(HEMA-co-AEMA) scaffolds were fabricated and characterized. While these scaffolds themselves are non-adhesive to cells, they were chemically modified with a mixture of two laminin-derived peptides, CDPGYIGSR and CQAASIKVAV, through a crosslinking agent, sulfo-(N-maleimidomethyl)cyclohexane-1-carboxylate (sulfo-SMCC), to promote cell adhesion and neurite outgrowth. The peptide modified P(HEMA- co-AEMA) scaffolds were easily fabricated in aqueous conditions, highly reproducible, well-defined, and enhanced neural cell adhesion and guided neurite outgrowth of primary chick dorsal root ganglia neurons relative to non-peptide-modified controls.

Cell Interactions with Polymers Protein adsorption to polymers. A polymeric material that is placed in solution or implanted in the body becomes coated with proteins quickly, usually within minutes.

Many of the subsequent interactions of cells with the material depend on, or derive from, the composition of the protein layer that forms on the Cited by: Basic principles: physical and chemical properties of polymeric biomaterials Chemistry is a constant factor from which the performance of most (polymeric) biomaterials can be predicted, but this.

The Polymeric scaffold synthesis and chemical modification for enhanced cell-polymer interaction. book material initially provides mechanical stability and also provides a template to guide three-dimensional cellular growth. The interaction of these two components, such as the coordination of polymer degradation rate with cellular synthesis rate, is critical for the success of tissue engineering.

In tissue engineering, biomolecular recognition of synthesized organic support (scaffold) by cells is essential to enhance the volume and surface modification of biomaterials. This recognition can be accomplished through chemical or physical methods, using bioactive molecules such as chains of native ECM proteins and small peptide sequences Cited by: Therefore, this approach is currently being used for the synthesis of highly multifunctional polymeric scaffolds with controllable assembly and characteristics.

Hydrogels have existed for more than half a century, and today they have many applications in various processes ranging from industrial to biological. There are numerous original papers, reviews, and monographs focused on the synthesis, properties, and applications of hydrogels.

In addition, chemical hydrolysis as opposed to enzymatic reactions is responsible for degradation of polymeric chains in vivo; thus degradation does not vary from patient to patient. However, PCL is not without drawbacks, as with all synthetic polymers, PCL implants experience fibrosis and gradually become isolated from the surrounding bone.
