Total RNA was extracted working with RNeasy kit (Qiagen, Germany) for developmental samples or Qiazol (Qiagen) for adult samples and cells as per manufacturer’s instructions. 5000 ng of total RNA have been reverse transcribed making use of Maxima Initially Strand cDNA Synthesis Kit (Thermo Fisher Scientific, Waltham, MA, USA) as per manufacturer’s instructions. qPCR reactions were performed using FastStart Important DNA Green Master (Roche) and Light Cycler 480 II (Roche). The sequences on the primers made use of and their specificity are the following: Krox20 (mouse and rat) forward 5’acagcctctacccggtggaagac3′, reverse 5’cagagatgggagcgaagctactcggata3′; cJun (mouse and rat) forward 5’gccaagaactcggaccttctcacgtc3′, reverse 5’tgatgtgcccattgctggactggatg3′; Oct6 (mouse) forward 5’gagcactcggacgaggatg3′, reverse 5’cacgttaccgtagagggtgc3′; Brn2 (mouse) forward 5’tcaaatgccctaagccctcg3′, reverse 5’cgggaggggtcatccttttc3′; Sox10 (mouse) forward 5’ccgaccagtaccctcacct3′, reverse 5’tcaatgaaggggcgcttgt3′; Sox2 (mouse) forward 5’ggaaagggttcttgctgggt3′, reverse 5’acgaaaacggtcttgccagt3′; Id2 (mouse) forward 5’catcagcatcctgtccttgc3′, reverse 5’Figlia et al. eLife 2017;6:e29241.

Relative mRNA fold modifications for each and every gene had been obtained by using the 2DDCt technique just after normalization to GAPDH, bactin, or atubulin.Plasmids and cloningTo generate lentiviral vectors for overexpression in SCs, the hPGK promoter in the pCCLsin.PPT. hPGK.PRE lentiviral backbone was replaced by a 1.1 kb fragment in the rat P0 promoter, as previ ously described (Norrme et al., 2014). myrAkt constructs were obtained from Addgene (9008, 9016, 9017) (Ramaswamy et al., 1999), PCRamplified, and inserted involving the AgeI and SalI restriction sites of the modified pCCLsin.PPT.hPGK.PRE vector. The 4EBP14xA construct was obtained from Addgene (38240) (Thoreen et al., 2012) and subcloned between the BamHI and NheI restriction sites on the pcDNA3.1 vector. As handle, the eGFP coding sequence in the pCCLsin.PPT.hPGK.PRE vector was subcloned among the NheI and EcoRI restriction web-sites with the pcDNA3.1 vector. All constructs have been sequenceverified prior to usage.Preparation, culture, and use of primary SCsTo prepare embryonic SCs, E13.five mouse DRGs had been isolated, digested with trypsinEDTA 0.25 (Life Technologies) for 30 min, resuspended in N2medium (Sophisticated DMEM:F12 plus N2 supplement (Life Technologies)) with 50 ng ml 7S NGF (Millipore), and plated on uncoated dishes. Soon after 1 week, the SCneuron network was mechanically detached in the underlying fibroblast layer, digested with 0.25 trypsin (SigmaAldrich, T9201) and 0.1 collagenase (SigmaAldrich, C0130), and replated on PLLcoated dishes in N2medium devoid of NGF. Just after reaching confluency, cells had been trypsinized, centrifuged, and resuspended in flow buffer (PBS plus two FCS (Life Technologies)). Flow cytometry experiments were performed with LSR Fortessa (BD Biosciences, Franklin Lakes, NJ, USA) utilizing in between 105 and 106 cells per genotype, plus the data had been analyzed with all the FlowJo software (RRID:SCR_008520, version 10.0.7).
