RWV bioreactor creates 3-D cell culture models

The cells and tissues in our bodies grow, develop and interact in a highly complex, three-dimensional world. Likewise, the various microbial pathogens that invade our bodies and cause infectious disease interact with this complex 3-D tissue milieu. In the current issue of the journal Nature Reviews Microbiology, researcher Cheryl Nickerson and her team at the Biodesign Institute at Arizona State University highlight an innovative approach for studying cells in 3-D.

Researchers investigate 'friendly bacteria' to kill bone cancer cells

Children and young people who are diagnosed with bone cancer could benefit from better treatment in the future thanks to new research at The University of Nottingham. The Bone Cancer Research Trust launches Bone Cancer Awareness Week today and has funded a new project at the University which is testing a theory that 'friendly bacteria' can be used to kill bone cancer cells.
