Piezoelectrically and Topographically Engineered Scaffolds for Accelerating Bone Regeneration.

Abstract in brief

• The study introduces a new scaffold for bone regeneration that combines piezoelectric properties, topographical features, and biocompatibility by integrating hydroxyapatite (HAp) into a piezoelectric polymer, aiming to mimic the natural environment of bone.
• These scaffolds can generate electrical stimuli in response to mechanical forces, which, along with their physical surface structures and biological signals, significantly enhance the process of bone healing.
• The research identifies three main mechanisms—electrical, topographical, and paracrine signaling—that work together to accelerate bone regeneration, offering promising applications in regenerative medicine.]
