The Nunclon Sphera from Thermo Scientific, Waltham, Mass, offers cancer researchers a non-adherent cell culture surface for the formation of consistent cancer and stem cell spheroids in vitro. An alternative to commonly used non-treated surfaces, the polymer-coated surface has very low-binding characteristics to allow different cell types to grow in suspension consistently with virtually no cell attachment. It also provides high quality for embryoid body formation of pluripotent stem cells, serving as a tool to investigate cell fate potential and lineage specificity of stem cells. The Nunclon Sphera is available in round and flat-bottom 96-well plates, single or multi-well dish and flask formats and is designed to facilitate an array of cancer and stem cell research, from routine passage of cells to high throughput imaging analysis.
