GC-1 spg Cells




















General information
Description | The GC-1 spg cell line was immortalized through transfection with the pSV3-neo plasmid, which harbors the coding sequences for the SV40 large T antigen and neomycin resistance. This genetic modification not only provides resistance to certain antibiotics but also promotes the continuous growth of the cells by altering their cell cycle regulation, thus bypassing the Hayflick limit typical of primary cells. This process of immortalization allows the cells to maintain proliferative capacity while retaining key phenotypic characteristics of spermatogonia. Phenotypically, the GC-1 spg cell line exhibits characteristics that are indicative of a transitional stage between type B spermatogonia and primary spermatocytes, making it an especially relevant model for studying the early stages of spermatogenesis. The cells express two testis-specific isoproteins: cytochrome c and lactate dehydrogenase C4. These markers are crucial for studying cell metabolism and energy management during spermatogenesis, reflecting the unique metabolic pathways active in germ cells. The expression of these specific isoproteins underscores the cell line's utility in exploring the biochemical and physiological aspects of testicular cell function and development. |

Handling
Culture Medium | DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 1.5 g/L NaHCO3, w: 1.0 mM Sodium pyruvate (Cytion article number 820300a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Passaging solution | Accutase |
Subculturing | 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. |

Quality control / Genetic profile / HLA
Sterility | 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. |
