ES-2 Cells

The ES-2 cell line is derived from a poorly differentiated ovarian clear cell carcinoma, offering a unique in vitro model to study the biological behaviors and treatment responses of this aggressive cancer subtype. Originally cultured in soft agar, a method favoring the growth of cancer cells while suppressing fibroblast growth, ES-2 cells provide a robust system for analyzing tumor cell interactions and drug resistance mechanisms in a three-dimensional matrix that closely mimics the in vivo environment. Pharmacologically, ES-2 cells display low to moderate resistance to several chemotherapeutic agents, including doxorubicin, cisplatin, carmustine, etoposide, and cyanomorpholinodoxorubicin (MRA-CN). This resistance profile makes ES-2 an essential tool for oncology research, particularly in the development and testing of new chemotherapeutic regimens and combination therapies. Furthermore, the expression of P-glycoprotein in ES-2 cells is low, which is significant as P-glycoprotein is often implicated in the efflux of drugs from cancer cells, contributing to multidrug resistance. Studying ES-2 cells can therefore provide insights into overcoming drug resistance in ovarian clear cell carcinomas.

• ES-2 305038-040324 Cytion CoA (PDF)

• Protein expression: P Glycoprotein
• Tumorigenic: Yes

• cultureMedium: McCoys 5a, w: 3.0 g/L Glucose, w: stable Glutamine, w: 2.0 mM Sodium pyruvate, w: 2.2 g/L NaHCO3 (Cytion article number 820200a)
• supplements: Supplement the medium with 10% FBS
• dissociationReagent: 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.
• fluidRenewal: 2 to 3 times per week
• freezeMedium: 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.
