Shining a Light on 3D Cell Culture.

The article reports on the use of three-dimensional (3D) bioreactor-based methods of cell culture by researchers in response to the limitations of traditional ways of growing cells. The two major factors to consider when growing cells in culture include cell growth rate and cell viability. The article also presents a proof-of-principle study, illustrating that real-time monitoring utilizing an optical sensor can offer useful cell culture insights.
