Indeed, similarly to what is seen for synthetic biomaterials, the application of composite technologies to bovine xenografts is becoming an interesting trend, not only in research [ 47 , 48 ] but also in industrial and clinical practices [ 49 , 50 ]: the adding of resorbable polymeric components improves mechanical and biological performances [ 51 ] and can also be used to locally carry active molecules, or drugs to be delivered locally, to increase cell colonization, promote osteoinduction and finally promote osteogenesis [ 52 , 53 ], hence, representing an increasingly interesting family of biomaterials. 3.
