Despite being the most widely used biomaterials in orthopedic surgery, metallic implants do not induce new bone growth because they are bioinert. Surface biofunctionalization of implants with immunomodulatory mediators is a recent approach to promote osteogenic factors that facilitate bone regeneration. Liposomes (Lip) can be used as a low-cost, efficient and simple immunomodulator to stimulate immune cells in favor of bone regeneration. Even though liposomal coating systems have been reported previously, their main disadvantage is their limited ability to preserve liposome integrity after drying. In order to address this issue, we developed a hybrid system in which liposomes could be embedded in a polymeric hydrogel namely gelatin methacryloyl (GelMA). Specifically, we have developed a novel versatile coating strategy using electrospray technology to coat implants with GelMA/Liposome without using adhesive intermediate layer. The two differently charged Lip (i.e., anionic and cationic) were blended with GelMA and coated via electrospray technology on the bone-implant surfaces. The results showed that the developed coating withstood mechanical stress during surgical replacement, and Lip inside GelMA coating stayed intact in different storage conditions for a minimum of 4 weeks. Surprisingly, bare Lip, either cationic or anionic, improved the osteogenesis of human Mesenchymal Stem Cells (MSCs) by inducing pro-inflammatory cytokines, even at a low dosage of Lip released from the GelMA coating. More importantly, we showed that the inflammatory response could be fine-tuned by selecting the Lip concentration, Lip/hydrogel ratio, and coating thickness to determine the timing of the release such that we can accommodate different clinical needs. These promising results pave the way to use these Lip coatings to load different types of therapeutic cargo for bone-implant applications.
