We synthesized a water-insoluble phospholipid polymer bearing a phenylboronic acid moiety (PMBV), which induces cell adhesion through a specific interaction with the glycoprotein, fibronectin. Surface plasmon resonance analysis revealed that fibronectin was adsorbed on the PMBV surface. When fibroblasts were cultured on the PMBV surface, the cells adhered and proliferated normally while showing a spherical morphology. In addition, the adherent cells were able to detach after the addition of sugar molecules, which bound to phenylboronic acid through an exchange reaction. The cell cycle of adherent cells was evaluated with the embedded HeLa-Fucci cells by using a fluorescent ubiquitination-based cell cycle indicator. The cell-cycle analysis by fluorescence microscopy indicated that the adherent HeLa-Fucci cells tended to converge to the G1 phase. The differentiation of mesenchymal stem cells to chondrocytes was accelerated on PMBV in the presence of bone morphogenetic protein-2. We concluded that PMBV is a useful surface in experiments for assessing cellular function and differentiation.
