Culturing PC-12 cells
The PC12 cell line neuronal model is widely used in neuroscience research. You should know the following important points to facilitate its easy and effective culturing. This section will include the PC-12 medium, doubling time, seeding density, cell culture protocols, and conditions.
Key Points for Culturing PC-12 Cells
|
Population Doubling Time: |
The PC-12 doubling time is approximately 40 hours. |
|
Adherent or in Suspension: |
PC12 neuronal cells grow in small clusters in suspension. They poorly adhere to non-coated surfaces and form patches on collagen. |
|
Seeding Density: |
The cell seeding density of the PC 12 cell line is kept at 1 x 104 cells/cm2. For suspension, cells are removed from the substrate by pipetting with a fresh culture medium. To obtain single cells, cells are passed through a 22-gauge needle and poured into new flasks. For cells grown on collagen, wash cells with PBS and incubate in a passaging solution (TrypleExpress) for 10 minutes. Afterward, add fresh media and centrifuge cells. Then, carefully resuspend the pellet and dispense cells into the culture vessel. |
|
Growth Medium: |
RPMI 1640 containing 10% fetal bovine serum, 2.1 mM stable Glutamine, and 2.0 g/L NaHCO3 is used to culture the PC 12 cell line. Media is renewed 2 to 3 times per week. |
|
Growth Conditions: |
PC-12 cultures are maintained in a 37°C humidified incubator with a 5% CO2 supply. |
|
Storage: |
PC-12 cells are stored in the vapor phase of liquid nitrogen or at below -150°C temperature to maintain cell viability for a longer term. |
|
Freezing Process and Medium: |
CM-1 or CM-ACF are used for freezing PC12 cells. A slow freezing method is used that allows the temperature to drop by 1°C. This prevents cells from any shock and maintains their viability. |
|
Thawing Process: |
Frozen PC-12 cells are thawed in a 37°C water bath. Afterward, cells are added with fresh media and centrifuged. This helps remove freezing media elements. Collected cells are resuspended and dispensed into the flask containing fresh growth medium. Freezing recovery takes almost 24 hours. |
|
Biosafety Level: |
Biosafety level 1 laboratory is required to culture the PC12 neuronal cells. |
