General information
| Description | PM-LGSOC-01 is a cell line derived from peritoneal metastasis of a low-grade serous ovarian carcinoma (LGSOC). This cell line was established as part of a comprehensive research model that also included a patient-derived xenograft (PDX). The creation of PM-LGSOC-01 involved orthotopic engraftment via subperitoneal tumor slurry injection in SCID/Beige mice, leading to an early-stage transplantable peritoneal metastasis (PM)-PDX model. Histological analysis confirmed that both the PM-PDX and PM-LGSOC-01 cells retained the micropapillary and cribriform growth patterns typical of LGSOC, with tumor budding, and expression of markers such as PAX8 and WT1. Genetic analysis showed that the primary tumor, the PM, and the cell line share a KRAS c.35 G > T (p.Gly12Val) mutation, making this model relevant for studying LGSOC progression and treatment response, particularly in relation to the MAPK pathway. PM-LGSOC-01 exhibits key characteristics relevant for preclinical research. It has a doubling time of approximately 42 hours in early passages, which decreased to 23 hours in later stages of cell culture, and has been maintained for over 100 in vitro passages. The cell line demonstrates epithelial morphology with Epithelial-like organization and high cell-cell adhesion. However, it shows limited response to platinum-based chemotherapy but is highly sensitive to paclitaxel (IC50: 6.3 ± 2.2 nM). Additionally, PM-LGSOC-01 is particularly sensitive to the MEK inhibitor trametinib (IC50: 7.2 ± 0.5 nM), both in vitro and in vivo, reflecting the impact of the KRAS mutation on therapeutic responses. PM-LGSOC-01 serves as a valuable tool for investigating LGSOC, particularly in the context of drug resistance, tumorigenicity, and sensitivity to targeted therapies like MEK inhibitors. Its use in developing personalized treatment approaches for low-grade serous ovarian carcinoma is critical, given the poor responsiveness of LGSOC to conventional chemotherapy compared to high-grade serous ovarian carcinoma (HGSOC). |

Handling
| Culture Medium | EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a) |
|---|---|
| Supplements | Supplement the medium with 10% FBS and 1% NEAA |
| Dissociation Reagent | Trypsin/EDTA and Ca2+/Mg2+ free phosphate buffer |
| Doubling time | 42 hours |
| 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. |
| Seeding density | 1 x 104 cells/cm2 |
| Freeze medium | 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. |
| Thawing and Culturing Cells |
|
| Incubation Atmosphere | 37°C, 5% CO2, humidified atmosphere. |
| Shipping Conditions | 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. |
| Storage Conditions | 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. |
Quality Control & Molecular Analysis
| 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. |
