Ons. Zebrafish wild-type TE line was raised at 28 . Embryos utilised for tumor injections have been maintained in E3 buffer supplemented with 0.2 mM 1-phenyl-2thiourea (PTU, Sigma).concentration of crizotinib (eight ) and 20a (100 ) as substances are applied towards the surrounding water and, because the estimated extent of compound absorption by the zebrafish larvae is one-tenth to one-twentieth of the cell culture treatment concentration [28, 72].Acknowledgements We thank Annika Bittmann, Aileen Mangang and Ramona Straub for all round excellent technical assistance. The neuroblastoma patient survival data were kindly offered by M. Fischer (University of Cologne, Germany). Help in the DKFZ Light Microscopy Facility is gratefully acknowledged.

FRK was supported by the Deutsche Krebshilfe (DKH) having a Mildred Scheel doctoral scholarship (quantity 112065).Cell preparation and xenotransplantationSK-N-BE(2)-C cells had been cultured to 70?0 confluence, then washed when with PBS (Lonza, Basel, Switzerland), trypsinized (Gibco), counted and resuspended in phenol red-free Roswell Park Memorial Institute 4-Chlorophenylacetic acid Data Sheet medium (RPMI, Gibco). Tumor cells have been labeled by incubation with CellTracker CM-DiI (Thermo Fisher Scientific, Waltham, MA, USA) for five min at 37 , and then for an more 15 min at 4 . To decrease cell clumping, DNase I (250 Kunitz units/ml, Sigma) was added towards the cell suspension. Following the incubation, cells were washed twice with ten FCS RPMI, twice with serum-free RPMI and resuspended in serum-free RPMI to a final concentration of 1.0 ?108 cell/ml. Ahead of implantation, zebrafish were anesthetized with tricaine (0.02 , Sigma) and embedded within a lateral position in 1.0 low gelling temperature agarose (Sigma). Involving 150 and 250 CM-DiI-labeled tumor cells were injected into the yolk sac of every single zebrafish larva using FemtoJet express microinjector (Eppendorf, Hamburg, Germany) and glass microinjection needles (Science Items, Hofheim, Germany). Larvae had been transferred to 34 1 h after tumor cell injection.Compliance with ethical standardsConflict of interest The authors declare that they have no conflict of interest.
