MLTC-1 Cells
















General information
Description | The MLTC-1 cell line, derived from murine Leydig tumor cells, retains the hormonal responsiveness of the original tumor. This cell line is particularly valuable for research into steroidogenesis and Leydig cell function. MLTC-1 cells exhibit key characteristics of Leydig cells, including the presence of luteinizing hormone (LH) receptors, which are crucial for the stimulation of testosterone production. These cells serve as a robust model for investigating the synthesis and secretion of steroid hormones, especially testosterone, which plays a significant role in male reproductive physiology. MLTC-1 cells respond to hormonal treatments in a manner similar to the original tumor cells. The activity of membrane adenyl cyclase is notably stimulated by treatments with human chorionic gonadotropin (hCG), luteinizing hormone, cholera toxin, sodium fluoride, and guanyl-5'-ylimidodiphosphate. Moreover, these cells produce progesterone in response to hCG, further underscoring their utility in studying hormonal regulation and signaling pathways. The MLTC-1 cell line is also employed in toxicological studies to assess the impact of various substances on Leydig cell function and steroidogenesis, making it an essential tool in reproductive biology and endocrinology research. |

Handling
Culture Medium | RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS, add 2.5 g/L glucose and 10 mM HEPES |
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. |
Split ratio | 1:2 to 1:4 |
Fluid renewal | 2 to 3 times per week |
Freeze medium | As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. |

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. |
