Cell cycle analysis was performed on untreated and 24 h treated cells with Rapha Myr® extract (0.5–1.25–2.5% v/v), according to Malfa et al., 2019 [70 (link)]. In order to assess cell cycle state, 1 × 106 cells were stained with propidium iodide (PI, 50 ng/mL) and analyzed by the FlowSight® (Amnis®, part of EMD Millipore) imaging flow cytometer. The cell distribution in each cell-cycle phase was determined by using IDEAS 6.0 image analysis software (Amnis Inc., Seattle, WA, USA).
