Difference in iPSCs and SCPCs intracellular iron levels allows MRR to pick up varying levels of iPSCs in SCPCs via T₂ measurements A Fe³⁺ fluorescent intensity of iPSCs and SCPCs analyzed via FACS showed a significant difference in Fe³ between the 2 cell types. B T₂ values of SCPCs were significantly higher than iPSCs. C Schematic of artificial spiking of iPSCs in SCPCs at 1%, 5% and 10% concentrations to alter SCPC T₂ measurements. D Decrement of T₂ values with increasing spiked iPSC concentration at 1%, 5% and 10% (n = 4). Statistical significance was determined by a Mann–Whitney u-test
