Caucasian-American derived extracellular matrix molecules (ECM) enhances the tumorigenicity of estrogen receptor (ER) + /progesterone receptor (PR) + breast cancer cells. (a) Indicates the number of tumors detected per animals injected. (b,c) Data represent mean ± SD of the final tumor volume of ER+/PR+ (T47D) or ER-/PR- (MDA-MB-231) breast cancer cells suspended in the indicated ECM and injected into the abdominal mammary gland. (d) Data represent mean ± SD of the final tumor volume of MDA-MB-231 breast cancer cells suspended in the indicated ECM and injected subcutaneously. AA = African-American, CAU = Caucasian-American.
