Uppsala University reported on Oct. 26 a research workflow that clears small cancer-cell spheroids with a fructose-and-glycerol solution, then profiles individual cells using multichannel fluorescence imaging and spinning-disk confocal optical sectioning. In a 52-drug study, the method distinguished responses that looked similar in flat cultures. The Oct. 27 edition covers this microscopy result, not a clinical treatment or approved diagnostic.
GLOBAL IMAGING BRIEF
Analysis: Optical clearing and cell-level imaging can expose heterogeneity hidden by aggregate 3D measurements. Adoption in screening will depend on throughput, reproducibility and validation across additional cell models.
