Electrospun Nanofibers Containing Strontium for Bone Tissue Engineering

Abstract EN

Electrospun polymer/metal composite nanofibers have received much attention in the field of bone tissue engineering and regenerative medicine (BTERM) owing to their extracellular matrix- (ECM-) like structure, sufficient mechanical strength, favorable biological properties, and bone induction.

In particular, electrospun nanofibers containing strontium (Sr) can significantly promote bone repair and regeneration by mediating osteolysis and osteogenesis, which offers a promising bioactive material for BTERM.

In this review, we summarized the effects of electrospun nanofibers containing Sr on stem cells, osteoblasts, and osteoclasts in BTERM.

Also, current challenges and future perspectives for electrospun nanofibers containing Sr in BTERM are briefly outlined.

It is hoped that the systematic overview will inspire the readers to further study Sr-containing nanofibers for BTERM and accelerate their translation from the bench to the clinic.
