A172 Cells

A-172 (A172 or A-172 MG) is a significant cell line used in neuroscience research. It originates from the brain tissue of a 53-year-old male with glioblastoma, a type of brain cancer. These cells adhere and spread on the surface of culture dishes, with a karyotype of n = 80 (80 chromosomes). A-172 cells are hypertriploid, exhibiting over 20 marker chromosomes. They have been shown to be non-tumorigenic in anti-thymocyte serum treated NIH Swiss mice. A-172 cells have a gene expression profile that highlights their mesenchymal lineage and involvement in angiogenesis.
They express genes related to mesenchymal markers (CD90, CD105, fibroblast activation protein, tenascin C) and angiogenesis inducers (VEGF, FGF2 (b), TGFb1, thrombospondin-1). Comparisons with the T98G cell line reveal differences in morphology and surface marker expression. Both cell lines show high expression of a2 smooth muscle actin. Changing the fetal serum concentration in the culture medium affects the proportion of cells expressing specific surface antigens, such as CD73 and CD105.
A-172 and T98G cell lines accurately represent glioblastomas, providing valuable tools for studying this brain tumor. Their gene expression profiles and morphological features allow for investigations into the molecular mechanisms underlying glioblastoma development and progression. Researchers can utilize A-172 cells to gain insights into glioblastoma biology and potentially identify new therapeutic targets for this devastating disease.

Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.

After thawing, plate the cells at 4 x 10^4 cells/cm^2 and allow the cells to recover from the freezing process and to adhere for at least 24 to 48 hours.

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

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.

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.

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

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.

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

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.

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

When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
