C17.2

The C17.2 cell line is a neural progenitor line derived from the mouse cerebellum using retroviral-mediated oncogene transfer with the avian myc gene. It is one of several lines developed to study the differentiation potential of neural progenitor cells, particularly focusing on neuron and glial cell lineages. C17.2 cells exhibit key characteristics of neural progenitors and can differentiate into both neuronal and glial cells under appropriate conditions, making them valuable for studies on neural development, neurogenesis, and gliogenesis.

One defining feature of C17.2 is its potential to differentiate into distinct neural cell types while maintaining mitotic potential, allowing for extended culture and experimental manipulation. This line expresses markers characteristic of neural stem and progenitor cells and can be induced to express lineage-specific markers depending on the differentiation protocol. The stability and multipotency of C17.2 enable its use in examining factors affecting lineage commitment in neural cells, as well as its application in neural repair and regeneration research.

Researchers employ C17.2 cells in both in vitro and in vivo contexts to understand mechanisms controlling cell fate within the central nervous system (CNS). In addition, the line’s well-characterized gene integration sites and consistent expression of specific neural markers make it a reliable model for neurodevelopmental studies and for exploring the potential therapeutic roles of neural progenitor cells in neurodegenerative disease models.

37°C, 5% CO₂, humidified atmosphere.

1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
