Cell Line Name

MCF7/TAMR-8

Cell Line Description

The MCF7/TAMR-8 cell line is a breast cancer cell line resistant to tamoxifen. Tamoxifen is by far the most widely used drug for hormone-dependent breast cancer. However, primary or acquired resistance to Tamoxifen severely limits its clinical effectiveness. The MCF7/TAMR-8 cell line is a good model cell to study the signalling pathways, which are the major drivers of tamoxifen-resistant growth.The parental cell line for the MCF7/TAMR-8 cells is MCF7/S0.5, which was adapted to grow at low serum concentration in order to study the effect of estradiol and tamoxifen. MCF7/TAMR-8 has been established from a clone of cells that survived long term treatment with 1 µM tamoxifen. Tamoxifen-resistant cells are passaged continuously in presence of 1 µM tamoxifen, which is lethal for the parental MCF7/S0.5 cell line

Cell Type

Epithelial

Subculture Routine

Split sub-confluent cultures at 70-80% confluency. Subculture cells using 0.05% trypsin/EDTA solution and soya bean trypsin inhibitor or TrypLE Express™(1X), without phenol red, and wash with phosphate- buffered saline (PBS). Pellet cells by centrifugation and re-suspend in growth medium. Initiate the culture at a dilution of approximately 1:3 to 1:6 i.e. seeding at 2-4x10⁴cells/cm². Incubate cultures in 5% CO₂ in air at 37°C. Recommend media changes every 2-3 days. Cells can be cryopreserved in either a mixture of cell line conditioned medium (45%) and fresh serum free-medium (45%) with 10% dimethyl sulphoxide (DMSO) or 90% Foetal Bovine Serum (FBS) and 10% dimethyl sulphoxide (DMSO). It is recommended that upon resuscitation the cells are washed in phosphate- buffered saline (PBS) or serum-free medium, pelleted by centrifugation and re-suspended in growth medium prior to initiation of culture.

Culture Medium

Phenol red-free DMEM:Ham's F-12 containing 1% foetal bovine serum, 2 mM Glutamax and 6 ng/ml insulin. To maintain high-level resistance, medium was supplemented with Tamoxifen (1 µM).

Growth Mode

Unless specified otherwise, at ECACC we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines (Advisory Committee on Dangerous Pathogens) (UK). All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.

Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
