Description
Osteoarthritis (OA) and osteoporosis (OP) are disabling, degenerative bone diseases with significant economic and societal impacts. The incidence of these conditions increases with age but in recent years the number of younger patients has increased, due mainly to factors related to modern life-styles.
The efficiency of current pharmacologic and implant-based solutions are limited and often poorly tolerated. OPHIS aimed to develop new, engineered biomaterials for the regeneration of both the osteo-chondral region and the vertebral body degenerated by OA and OP. These devices were based on the unique combination of biological triggers in the form of (i) nanostructured biomaterials able to mimic the extracellular matrices of either bone or cartilage (ii) chemical and biochemical cues able to direct, control and preserve the phenotypes of the relevant cells in their respective histological compartments.
OPHIS explored the frontiers of knowledge of the effect of nano-structures on tissue regeneration and lead to the de-novo design of active structures able to trigger this process. User friendly and highly performing tissue substitutes were developed as both acellular and cellular matrices for the regeneration of specific anatomical regions compromised by OA and OP. Focus was also given to the study of the interactions occurring at nano-scale level between the implanted materials and the natural tissues. This information complements the body of data obtained through clinically reflective in vitro and in vivo models. Dissemination was integrated step-wise with the strategy for intellectual property protection and exploitation.

Key findings
All the milestones foreseen in OPHIS were reached in time. The main results and achievements of the project OPHIS are summarised as follows:
> New bio-polymeric matrices and blends suitable for guided assembling/mineralisation and generation of 3D scaffolds for bone and osteochondral regeneration with designed composition and microstructure.
> New hybrid bone and osteochondral scaffolds presenting dendrimer-mediated functionalisation triggering bone and vascular regeneration.
> Apatite nano-phases with multiple bio-competent ion-substitution.
> New αTCP phases presenting tailored substitution with strontium.
> New injectable, self-setting pastes based on Sr-αTCP with tailored viscosity, setting time and mechanical strength.
> New injectable self-setting cements based on Sr-substituted apatites with enhanced osteogenic and osteoconductive ability.
> New alginate-based osteochondral scaffolds.
> New bone scaffolds based on bacterial nanocellulose.
> New semi-dendrimers exposing O2 scavengers as triggers of chondrocytic differentiation.
> New semi-dendrimers mediating gene transfection.
> New peptide sequences mimicking bone (BMP-2), cartilage (IGF-1) and vascular (VEGF) growth factors.
> New polymeric nanobeads with controlled size and ability of controlled delivery.
> New pH-sensitive bio-polymeric constructs with ability of controlled delivery.
> Preliminary assessment of a AFM nanoindentation-based method to predict, in a quantitatively and spatially resolved way, the behaviour of grafts for osteochondral regeneration upon implantation.
Following in vitro testing to verify their cellular compatibility, the biomaterials developed by the OPHIS consortium hold great exploitation potential and could prove beneficial for sufferers of degenerative bone disorders.
