General information and origin of the PC-12 cell line

Understanding a cell line's general attributes and origin is crucial before commencing work on it. This section will help you learn vital information about the PC12 cell line. Here, you will know: What is the PC12 cell line in pheochromocytoma? How are PC12 cells differentiated? What is the origin of PC12? What is the size of a PC12 cell?

• PC12 neuronal cells are similar to the primary culture of fetal neurons. They were obtained from pheochromocytoma of the rat adrenal medulla. These cells are of embryonic origin, resembling a mixture of eosinophilic and neuroblastic cells [1].
• PC12 cells function as catecholamine cells. They synthesize, store, and secrete dopamine and norepinephrine.
• Pheochromocytoma (PC12) cells have a diameter of 10 to 12 µm.
• PC-12 cells possess a polygonal-shaped morphology.
• PC-12 cells have a homogeneous and near-diploid number of chromosomes (n=40).

The greater splanchnic nerve helps with the motility of the foregut and provides sympathetic innervation to the adrenal medulla.

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.

PC-12 Cell Line: A Versatile Tool in Neurobiological and Cancer Research

PC12 cell lines, originating from rat pheochromocytoma, serve a pivotal role in neurobiological research, acclaimed for their neuronal characteristic expressions such as neurite outgrowth in response to nerve growth factor (NGF). The versatility of PC12 cells is harnessed extensively in neurobiology for exploring neural differentiation, responses to neurotrophic factors, and neurotoxicity assessments. This unique propensity for differentiation into neuron-like cells upon NGF exposure renders them an indispensable asset for researchers delving into the complexities of the nervous system.

Neuroregeneration and Cell Differentiation

Intriguingly, a study explored the influence of dental pulp stem cells and their derived factors on the differentiation, survival, and expansion of PC12 cells, unveiling promising paths for neuroregeneration [3]. Another investigation spotlighted Osteocalcin, a bone-derived protein known for its calcium-binding capacity, as a promoter of survival, proliferation, and differentiation in PC12 cells [4], highlighting the protein's potential in enhancing neuronal attributes.

Drug Screening and Neuroprotection

The utility of PC12 cells extends to drug screening, particularly for evaluating neuroprotective and neurodegenerative compounds, marking a critical phase in the quest for novel neurodegenerative disease treatments. For instance, research underscored the neuroprotective properties of α-bisabolol in a Parkinson's disease model employing PC12 cells, evidencing α-bisabolol's capability to mitigate amyloidogenesis and apoptosis while also modulating the neurotoxic effects of amyloid beta [5].

Cellular Transformation and Neural Networks

The process of differentiation from a PC-12 cell to a neuron-like entity commences with NGF, a pivotal protein essential for neuronal growth and survival. Exposure of PC-12 cells to NGF activates complex intracellular pathways, laying the groundwork for their transformation. This metamorphosis is a gradual revelation of cellular potential, observable under a microscope as the cells extend neurites and forge connections akin to neuronal networks.

Morphological Changes and Neuronal Phenotype

Differentiation imparts significant morphological and functional transformations to PC-12 cells. From their initial round or slightly elongated form, growing in suspension or as an adherent monolayer, NGF treatment propels them to exhibit extended neurites, signifying a profound shift towards a neuronal phenotype. These neurite outgrowths are crucial for cellular communication and interaction, reflecting the connectivity inherent in neuronal tissues.

Cancer Research and Cellular Mechanisms

In cancer research, the neuronal model offered by PC12 cells finds relevance owing to their tumorigenic origin. These cells are instrumental in probing cancer cell proliferation, invasion, and migration mechanisms. A 2020 study delved into the impact of Ferula assa-foetida extract on PC12 cell proliferation, shedding light on its potential therapeutic applications [7].

Stroke Research and Neuroprotective Strategies

Moreover, PC12 ADH cells, a variant adhering to culture surfaces, enable in-depth analyses of cell morphology and responses to stimuli like oxygen-glucose deprivation, serving as an essential model for stroke research and neuroprotective agent evaluation. The rapid doubling time of PC12 cells, ranging from 24 to 48 hours, underscores their efficacy in dynamic studies where cell proliferation rates are crucial.

Concluding Remarks on PC12 Cell Applications

In essence, PC12 cells and their derivatives embody a versatile model for a wide array of research applications spanning neurobiology, drug discovery, and cancer studies.
