Organoids have the potential to bridge 3D cell culture to tissue physiology by providing a model resembling in vivo organs. We propose here a SILAC method to measure protein expression changes in intestinal organoids under different experimental conditions. With the combined use of quantitative mass spectrometry, SILAC and organoid culture, we validated the approach and showed that large-scale proteome variations can be measured in an “organ-like” system under variable conditions.
