Label-free characterization of organoids with quantitative confocal Raman spectral imaging

Stem cell-derived organoids have the potential to significantly improve the drug discovery process. However, a key challenge is monitoring the maturation process and drug response. In this issue of Cell Reports Methods, LaLone et al. have shown that quantitative confocal Raman spectral imaging, a label-free technique, can reliably monitor organoid development, drug accumulation, and drug metabolism.
