Treatment of cells Withdrawal of trophic factors [TFs; BDNF, GDNF, and ciliary neurotrophic factor (CNTF)] is a well-established method to activate neuronal apoptosis (Yang et al., 2013). To initiate cell death in our cultures, we withdrew TF support along with B27 and N2 supplements from MNs (TFC) at day 1 (1 day after live imaging initiation). To study the early processes that underlie MN death by TF withdrawal, as well as to distinguish different actions of kenpaullone and TF addback treatment on the MNs deprived of TF at day 1, TFs (BDNF, GDNF, CNTF, B27, and N2) were reintroduced to the cultures (defined as TF addback) at varying lengths of time (6, 7, or 8 days) after their withdrawal. For kenpaullone treatment, two different concentrations (2.5 and 5 m) TMC-207 were supplied to MNs through the entire period where they were taken care of in the lack of TF. Assay advancement for computerized live time-lapse imaging To get ready MNs for live imaging, day time 21 EBs had been dissociated with Accutase, triturated until no clumps had been noticeable, and seeded into 96-well Very clear black-walled plates (Greiner Bio-One; Kitty # 655090) with major mouse glia as feeder cells, and taken care of with BDNF (10 ng/ml), GDNF (10 ng/ml), and CNTF TMC-207 (10 ng/ml).
