Abstract
Nowadays, tendon injuries represent a global health issue that annually affects millions of individuals. An innovative approach for their treatment is represented by the development of tissue engineered scaffolds able to support the host cells adhesion, differentiation, and proliferation. However, the scaffold alone could be insufficient to guarantee an improvement of healing control. Magnetite nanoparticles (Fe3O4 NPs) are gaining interest due to their unique properties. In particular, when combined with bio-mimetic scaffolds, they should lead to the cells mechano-stimulation, improving the tenogenic differentiation and allowing a deeper tissue reparation.
The aim of this work is the study and the development of scaffolds based on polyhydroxybutyrate and gelatin and doped with Fe3O4 NPs. The scaffolds are characterized by an aligned fibrous shape able to mimic the tendon fascicles. Moreover, they possess a superparamagnetic behavior and a slow degradation rate that should guarantee structural support during the tissue regeneration. The magnetic scaffolds promote cell proliferation and alignment onto the matrix, in particular when combined with the application of an external magnetic field. Also, the cells are able to differentiate and produce collagen I extracellular matrix. Finally, the magnetic scaffold in vivo promotes complete tissue healing after 1 week of treatment when combined with the external magnetic stimulation.
