AB Bone’s inherent piezoelectricity is a key factor in regulating bone growth and mesenchymal stem cells (MSCs)fate towards the osteogenic lineage. The piezoelectric polymer poly(vinylidene) fluoride (PVDF) was thus used tomanufacture electroactive membranes by means of non-solvent induced phase separation (NIPS), producingporous membranes with approximately 90% of γ-phase for MSCs culture. The combination of the porous surfaceand PVDF hydrophobicity hinders cell adhesion and requires a coating to improve cell culture conditions. Alayer-by-layer (LbL) method was used to deposit elastin-like recombinamers (ELRs) containing RGD sequencesapplying click cross-linking chemistry. ELRs potential was confirmed by comparing traditional fibronectinadsorption with ELRs LbL on PVDF electroactive membranes. Porcine bone marrow MSCs preferred ELRs-coatedsurfaces, which enhanced initial cell adhesion and improved proliferation after 7 days. These findings lead tonew possibilities for regenerative therapies in the area of bone tissue engineering, offering the advantages of MSCcommitment towards the osteogenic lineage by applying electro-mechanical stimulation on electroactivesubstrates.
