Staining with mitochondrial markers. Ascites‐derived tumor spheroids and tumoroids from tumor tissue were stained with markers for mitochondrial mass and membrane potential using MitoTracker green FM and MitoTracker Red CMXRos, respectively. (A) Evaluation using flow cytometry showed high mitochondria mass levels in all samples and two subpopulations with different mitochondrial membrane potential. The subpopulation showing a higher mitochondrial membrane potential has been quantified in all samples including three matched pairs. (B) Confocal microscopy analyses (60×) ascites‐derived tumor spheroids and tumoroids from tumor tissue stained with MitoTracker green FM and MitoTracker Red CMXRos.
