Fig. 1From: Chemotherapy Cytotoxicity of Human MCF-7 and MDA-MB 231 Breast Cancer Cells Is Altered by Osteoblast-Derived Growth FactorsEffects of adriamycin (100 nM) on number of ER+ MCF-7 cells (■) and ER− MDA-MB 231 cells (▨) in monolayer cultures. Cells were cultured using DMEM/F-12 media supplemented with 5% calf serum (CS) and exposed to adriamycin for 48 hr. Adriamycin significantly decreased the number of both MCF-7 and MDA-MB 231 cells.Back to article page
