The surfaces and interfaces of biomaterials interact with the biological systems in multi-scale levels
and thereby influence the biological functions and comprehensive performance
in vitro
and
in vivo
. In particular
a surface promoting the selective adhesion and directional migration of desired types of cells in complex environment is extremely important in the repair and regeneration of tissues such as peripheral nerve and blood vessel
and long-term application of intracorporal devices such as intravascular implants. Therefore
surface modification of biomaterials is a facile and effective method to achieve the desired cell-biomaterials interactions. In this short review
recent advances on the surface modification of biomaterials to regulate selective cell adhesion and migration are briefly summarized. In particular
the surface properties of biomaterials are manipulated
via
the convenient introduction of amino groups to the ester-based polymers
the formation of polyelectrolyte multilayers
and the fabrication of topology and gradient cues
etc
.
followed by the association of chemical and biological signals such as collagen
heparin
hyaluronic acid
peptides and cell growth factors. The selective adhesion and directional migration of various types of cells such as endothelial cells (ECs)
smooth muscle cells (SMCs)
hepatocytes and Schwann cells (SCs) are achieved over the competitive counterpart cells by the use of cell-resisting substances and cell-selective motifs on gradient substrates in most cases. Recent advances on cell behaviors in three-dimensional (3D) cell-extracellular matrix (ECM)-mimicking substrates are also reviewed.
