报告内容简介:

This seminar highlights our recent efforts in understanding how to regulate cell behaviors and functions through controllable substrate characteristics, aiming to facilitate diverse tissue engineering applications such as bone, nerve, and cardiovascular repair and regeneration. The biodegradable materials developed and studied in our laboratory include polymers, nanocomposites, and inorganic materials. Used as model systems, photo-crosslinkable and biodegradable poly(e-caprolactone) acrylates (PCLAs), poly(ethylene glycol) diacrylates (PEGDAs), and photo-polymerizable poly(L-lysine) (PLL) and poly(ethylene glycol) (PEG) monoacrylates synthesized via facile methods have been photo-crosslinked into networks with tunable characteristics for regulating cell fate. By varying crosslinking density and crystallinity simultaneously, the mechanical properties of PCLA networks can be controlled efficiently. We have also modified PCLA networks and PEGDA-based hydrogels by tethering PEG or PLL chains to regulate surface chemistry and biocompatibility. Bulk and surface characteristics such as stiffness, morphology, hydrophilicity, and the capability of adsorbing serum proteins have been examined and correlated with the behaviors and functions of various cell types. Using these polymers, substrates with microfabricated or self-assembled surface patterns such as concentric or parallel microgrooves, micropillar arrays, nanofiber arrays, and honeycomb structures have also been prepared to explore the effects of these biomimetic surface morphologies on cell adhesion, spreading, proliferation, motility/migration, alignment, differentiation, and integrin/gene/protein expression. These research projects not only supply novel biomaterials and medical strategies for tissue engineering applications, but also offer excellent model systems to investigate fundamental correlation between surface characteristics and cell functions. Both aspects will help emphasize the role of materials science in fostering biomedical sciences.
