|
| Source name |
Control hiPSC 2623

|
| Treatment protocol |
Human pluripotent stem cells were plated and differentiated into putative Schwann cells. Briefly, colonies of pluripotent cells were rendered into single cells and plated on Geltrex, an artificial basement membrane-like matrix, in accordance with previous protocols9. They were then treated with a combination of small molecules to induce neuronal and Schwann cell differentiation. On day 0, to initiate differentiation, aspirate the medium and add KSR medium containing 10 μM SB-431542 and 500 nM LDN-193189. On day 2 change medium to KSR medium containing 10 μM SB-431542, 500 nM LDN-193189, 3 μM CHIR 99021, 10 μM DAPT. On day 4 change medium to KSR/NB (3:1) medium containing 3 μM CHIR 99021 and 10 μM DAPT (final concentrations are for the combined KSR/NB mixture). On day 6, change medium to KSR/NB (1:1) medium containing 3 μM CHIR 99021 and 10 μM DAPT. On day 8, change medium to KSR/NB (1:3) medium containing 3 μM CHIR 99021 and 10 μM DAPT. On day 10, 14, and 18 change medium to NB medium containing 200 μM dibutyrl cAMP and 200 μM sodium L-ascorbate. Maintain in this manner until day 21-23 of differentiation, when the cells are ready for purification. Schwann cells were purified with Fluorescence Activated Cell Sorting (FACS) after 21-23 days of differentiation using a PE-conjugated antibody to the alpha4 integrin, CD49d (R&D Systems, FAB1354P), and then utilized for gene expression profiling.

| Growth protocol |
hiPSCs and hESCs were maintained on MEF feeder layers through weekly passaging for up to 50 passages. Daily media change was performed with human ESC media.

| Description |
gene expression data from hiPSCs differentiated into Schwann cells for 21 days
BMuk-IPS-Cntl22-1a-HuPrView_(PrimeView).CEL
|
| Data processing |
Affymetrix CEL files were extracted and their data normalized with the Partek GS 6.6 platform. RMA normalization was used to create quantile-normalized log2 transcript signal values, which were used in subsequent ANOVA analyses.
