一般資訊
| 說明 | The MMQ cell line is a clonal, prolactin-secreting cell line derived from the 7315a rat pituitary tumor. It exclusively secretes prolactin and expresses functional dopamine receptors, specifically of the D2 subtype. Dopamine inhibits prolactin (PRL) release by reducing intracellular cyclic AMP (cAMP) levels and calcium uptake, as demonstrated in various experiments. This inhibition is reversed by haloperidol and pertussis toxin, confirming the role of GTP-binding proteins in dopamine's action. MMQ cells are also responsive to somatostatin (SRIF) and vasoactive intestinal polypeptide (VIP), but not to TRH, angiotensin II, or neurotensin. MMQ cells proliferate rapidly, doubling in less than 24 hours under optimal conditions. When transplanted into rats, MMQ cells form tumors that increase serum prolactin levels without altering other hormones such as ACTH. This cell line is an important model for studying prolactin regulation, particularly in relation to dopamine and its inhibitory mechanisms on prolactin secretion. |

處理方式
| 培養基 | RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
|---|---|
| 營養補充品 | Supplement the medium with 7.5% horse serum, 2.5% heat-inactivated FBS |
| 傳代培養 | Maintain cultures by periodically adding or replacing the medium. Initiate cultures with a density of 5 x 105 cells/ml and keep the cell concentration within the range of 3 x 105 to 1 x 106 cells/ml for optimal growth. |
| 播種密度 | > 2 x 105 cells/ml |
| 冷凍培養基 | As a cryopreservation medium, we 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. |
| 細胞解凍與培養 |
|
| 培養環境 | 37°C, 5% CO2, humidified atmosphere. |
| 運送條款 | 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. |
| 儲存條件 | 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. |
品質控制與分子分析
| 不孕症 | 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. |
