细胞系描述

The MCF7/AnaR-4 cell Line was developed as a model of resistance to anti-cancer treatment with aromatase inhibitors. This breast cancer cell line resistant to the aromatase inhibitor anastrozole and is oestrogen receptor positive.
Derivation: Anastrozole-resistant cell lines were established from MCF7 cells grown in medium with 10% newborn calf serum (NCS) and 10^-7 Molar testosterone. A culture of MCF7 cells were treated with 10^-7 Molar anastrozole for one week, trypsinized and seeded in serial dilutions in 24-well plates. Single colonies were transferred to new wells and gradually expanded in medium with anastrozole. After ~2–3 months, the isolated colonies gave rise to anastrozole-resistant cell lines, which could be grown in anastrozole-containing medium with a weekly split ratio of ~1:25. The MCF7 cell line was authenticated in January 2014 by DNA profiling using short tandem repeat loci and found to be matching the genetic profile reported for the MCF7 cell line.

培养基

Phenol red free DMEM:F12 (1:1) (D6434) + 10% Newborn Calf Serum(NBCS) (N4637) + 2.5 mM Ala-Gln (G8541) + 6 ng/ ml Insulin (I9278), 0.1 uM testosterone and 0.1 uM anastrozole

传代培养常规

Split sub-confluent cultures (70-80%). The MCF-7/AnaR-2 cell Line is sub-cultured once a week with a split ratio of approximately 1:25 and growth medium changed every second or third day. New culture are seeded at 2-4 x 10,000 cells/cm² using 0.25% trypsin or trypsin or 0.05%trypsin/EDTA solution; 5% CO₂; 37℃. Recommend media changes every 2-3 days
