Stem cell-mediated functionalization of titanium implants.

Prosthetic implants are used daily to treat edentulous people and to restore mobility in patients affected by skeletal defects. Titanium (Ti) is the material of choice in prosthetics, because it can form a stable bond with the surrounding bone following implantation-a process known as osseointegration. Yet, full integration of prosthetic implants takes time, and fails in clinical situations characterized by limited bone quantity and/or compromised regenerative capacity, and in at-risk patients.
