We are working on breast cancer with the main focus on luminal B tumours.
We have been using BT474, ZR751 and ZR7530 cell lines as a model for luminal B breast tumour, but recently I came across some article that have classified ZR751 as luminal A.
I am confused about ZR751 sub-classification and need some help to clarify the most authentic opinion in scientific community.
Can any one also suggest me if there are some other luminal B cell lines as all of these have quite long doubling time?
