Sample GSM5029099 Query DataSets for GSM5029099
Status Public on Jul 25, 2023
Title RL383_NeuN_invitro_methylC_rep1
Sample type SRA
Source name mESC-derived NeuN positive neurons day 38
Organism Mus musculus
Characteristics cell line: G4
cell type: mESC-derived NeuN positive neurons day 38
cell culture: in vitro
age: 38 days
Treatment protocol High potassium-mediated depolarisation was performed by washing cells with low K+ buffer, transferring to high K+ buffer for 5 min, washed again in low K+ buffer and either harvested directly for RNA, immediately fixed for ICC, or chased in growth medium for the appropriate times prior to fixation or RNA extraction.
Growth protocol mESC cells lines R1 and G4 were maintained on gamma-irradiated mouse embryonic fibroblasts in mESC medium with LIF. Cells were fed daily and split based on confluency. Neural differentiation was initiated by dissociating the mESC colonies using Accutase and excess feeder cells were removed from the cell suspensions by panning on gelatin-coated plates. Dissociated cells were counted and transferred to ultra-low attachment cell culture plates at a dilution of 220,000 cells/ml, in differentiation medium. Neural induction was continued for 8 days, medium was changed every two days, and supplemented with 5 µM retinoic acid for the final 4 days. Cell aggregates were dissociated using Accutase, single cell selected through a 40 µm cell strainer, and plated onto poly-ornithine / laminin-coated plates in N2 medium. After 2 days, cells were changed into N2B27 which was changed every 4 days for 12 days, following which 50% media changes were performed for the remaining culture time.
