The FRAP assay was performed with adaptations from Huis in ’t Veld et al. (2014) (link) and Chan et al. (2012) (link) and are described in the Supplemental Material. Cells were synchronized by 100 ng/mL nocodazole for 7.5 h and then released into medium containing 0.5 mM of auxin. Five hours or 6 h after release, 40 µL of cells was transferred into 15 µ-slide angiogenesis ibiTreat chamber slides (ibidi 81506), and remaining cells were fixed by 70% EtOH for cell cycle analysis by propidium iodide staining. During imaging, cells were cultured in normal medium at 39.5°C and 5% CO2.
