Cartilage repair with microbots and stem cells

Bioengineers at Chonnam National University in South Korea and at the Korea Institute of Medical Microbiotics have shown how microrobots carrying mesenchymal stem cells (MSC) can be targeted to damaged knee cartilage. “In this study, we propose a human adipose–derived MSC–based medical microrobot system for knee cartilage regeneration and present an in vivo trial to verify the efficacy of the microrobot using the cartilage defect model. The microrobot system consists of a microrobot body capable of supporting MSCs, an electromagnetic actuation system for three-dimensional targeting of the microrobot, and a magnet for fixation of the microrobot to the damaged cartilage.”    MORE
