obtained from ATCC, cultured in Advanced DMEM (ThermoFisher Scientific)
supplemented with 3% FBS (Altantis) and Glutamax-I (ThermoFisher
Scientific), and used within 5 passages with routine mycoplasma screening.
Ferret embryonic fibroblasts (FEFs) and mouse embryonic fibroblasts (MEFs) were
derived from post fertilization day 35 and 14.5 embryos, respectively. FEFs and
MEFs were cultured in AmnioMAX (ThermoFisher Scientific). Cells were transfected
with validated siRNA to ASPM or PRKCZ encoding
aPKCζ (ThermoFisher Scientific) using Oligofectamine and OptiMEM
(ThermoFisher Scientific) according to manufacturer’s instructions and
analyzed 48 h later.
