A tissue engineering approach based on the use of bioceramics for bone repair
Abstract
Biomimetics takes advantage of natural strategies for the solution of technological problems, including the proper design of biomaterials. Living bone exhibits a hierarchical porosity with both giant and nanometric pores which must be reproduced for the design of biomaterials for hard tissue repair. Bioactive and degradable bioceramics are a good alternative for the manufacture of scaffolds. Tissue engineering approaches to improve bone regeneration include strategies supporting endogenous osteoblast adhesion, proliferation (osteoconduction), osteoinduction by growth factors, and osteoprogenitors. Understanding the natural ossification mechanisms and the role of biomolecules involved in this process is a requirement for the design of bone tissue scaffolds. Mesoporous bioactive ceramics, namely mesoporous
