제목 Substrate-tethered artificial membranes with functional membrane proteins
초록 Manipulating a cell/tissue interactive surface is a crucial way to develop long-term implantable materials. Here, we produced particular interfaces with cellular membrane proteins to modulate selective interactions with inherent cells. In the first study, for the fabrication of a neuro-specific interface, neural-specific cell adhesion molecules (CAM,L1) containing vesicles extracted from differentiated PC-12 cells was used to formed a lipid bilayer tethered on titanium surface. The modified surface was successful in air stability and biofouling standpoints. In-vitro study confirmed that modified substrate provides a highly biocompatible surface for neuron cells; in contrast, it limits the astrocyte cell activation and local inflammation. In the second study, we are investigating on lipid bilayers incorporating galectin-1 protein (Gal-1).
