Functionalized Bioink Delivering Biomolecules for the Treatment of Craniofacial Diseases

2 aliquots of patients-derived bone tissue specimens (collected as surgical waste from routinely surgeries) will be collected and exploited from proteins and metabolites isolation according to standardized protocol. Then, samples will be digested using Filter-aided sample preparation digestion protocol and analysed by Liquid Chromatography Tandem Mass Spectrometry. Peptides will be loaded on the PepMap 100 C18 trap cartridge, and subsequently separated on an EASY Spray C18 analytical column. The mass spectrometer, equipped with a nanoESI spray source, operates in positive ion polarity and MS/MS mode. Also metabolites will be assessed by LC-MS/MS and will be separated by HPLC. Obtained results will be analyzed by integrated pathway analysis (IPA) to achieve the multiomic profiling of each patient thus identifying druggable targets to be exploited in drug design. The selected biomolecules will be then tested in patient cells using the developed bioink-nanoparticle complex.
