Researchers at the University of Michigan have created a biological scaffold for tissue engineering and regeneration that is responsive to focused ultrasound–released growth factors. How is their design different from the scaffolds that are currently used? Meanwhile, scientists in Shanghai are determining if focused ultrasound treatment of painful bone metastases could also improve quality of life for patients living with this disease?

Researchers at the University of Michigan have developed acoustically-responsive fibrin scaffolds containing sonosensitive emulsions that can be released with focused ultrasound. Could these controllable scaffolds replace tissue engineering’s traditional hydrogel scaffolds for creating tissue regeneration in bone, blood vessels, or other areas?

Evaluation of Quality of Life Using EORTC QLQ‐BM22 in Patients with Bone Metastases after Treatment with Magnetic Resonance Guided Focused Ultrasound
Focused ultrasound can alleviate the pain from bone metastases, but does it also improve quality of life for patients living with cancer? Scientists in Shanghai, China conducted a retrospective study of 26 patients to measure both pain and quality of life up to one year after treatment of the metastases. How much improvement did they find? See Orthopaedic Surgery >
