Notes
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130?, preferably in liquid nitrogen vapor phase storage, until ready for use.To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130? or in liquid nitrogen vapor phase. Do not store at -70?, as it will result in loss of viability.

Propagation
Grow the cells in culture vessel pre-coated with 50 mug/ml poly-L-ornithine (PLO) (TM062) and 1 mug/ml fibronectin (EMD Millipore; Cat. FC010) in H2O for at least 3 hours at 37°C. Do not grow these cells in culture vessels with surface areas equal to less than 12.5 cm2. These cells do not grow in 6-well, 24-well, 48-well, or 96-well plates.The base medium for this cell line is Advanced DMEM/F12 (Gibco;12634010). To make the complete growth medium, add the following components to the base medium: N2 supplement (ThermoFisher Scientific) to a final concentration of 1X, L-glutamine (G275) to a final concentration of 2 mM, and Recombinant Human FGF2 (Z101455) to a final concentration of 40 ng/ml.Change media every 2-3 days. Do not let media colour change to orange-yellow.The cells will form round clumps instead of a monolayer when stressed. It is recommended to subculture when cells are grown to a cell density of 50-60%.Carbon dioxide (CO2): 5%, Temperature: 37.0°C.To subculture the cells, use 0.25% Trypsin-EDTA (TM051). After adding trypsin, incubate the cells at room temperature for 2-3 minutes and agitate the culture vessel until 90% of the cells have detached. Immediately neutralize the trypsin using Trypsin Neutralizing Solution (Lonza, Cat. CC-5002). Add Trypsin Neutralizing Solution twice the volume of trypsin used. Centrifuge at 200x g for 2-3 minutes. Aspirate supernatant and resuspend cells in complete media. Plate cells into pre-warmed PLO-fibronectin-coated vessels at 37.0°C. Avoid subculturing if the cells appear stressed. Note: If leaving the cells over the weekend (or more than 2 days), make sure to do a high split ratio (1:4 to 1:5).To differentiate the cells into neurons, change the medium to differentiation medium after the cells have grown to a density of 40-50%.To make complete differentiation medium, add the following components to Advanced DMEM/F12 (Gibco;12634010): N2 supplement to a final concentration of 1X, L-glutamine (G275) to a final concentration of 2 mM, dbcAMP to a final concentration of 1 mM, tetracycline to a final concentration of 1 mug/ml, and Recombinant Human GDNF (Z101055) to a final concentration of 2 ng/ml. Allow the cells to grow in differentiation medium for 4-6 days before testing for neuron specific markers.

Thawing Protocol
1. Thaw cells quickly in a 37? water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions.
Subculture Protocol
Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 80% confluent. 1. Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel. 2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37?, for several minutes to facilitate detachment. 3. Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel. 4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type. 5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired. 6. Incubate the cells at the recommended conditions.
