The design of
biomimetic materials for biomaterials and tissue engineering applications that are capable of eliciting specific cellular responses
and directing new tissue formation mediated by biomolecular recognition, which
can be manipulated by altering design parameters of the material. Biomolecular
recognition of materials by cells has been achieved by surface and bulk
modification of biomaterials via chemical or physical methods with bioactive
molecules such as a native long chain of extracellular matrix (ECM) proteins as
well as short peptide sequences derived from intact ECM proteins that can incur
specific interactions with cell receptors. The biomimetic materials potentially
mimic many roles of ECM in tissues. For example, biomimetic scaffolds can
provide biological cues for cell–matrix interactions to promote tissue growth,
and the incorporation of peptide sequences into materials can also make the
material degradable by specific protease enzymes. This discusses the surface
and bulk modification of biomaterials with cell recognition molecules to design
biomimetic materials for tissue engineering. The criteria to design biomimetic
materials such as the concentration and spatial distribution of modified
bioactive molecules are addressed. Recent advances for the development of
biomimetic materials in bone, nerve, and cardiovascular tissue engineering are
also summarized.
