Figure 2. Breast cancer cell lines induce tumors in nude mice and metastasize to different organs.

(A) Five female BALB/c nude mice received an injection of different breast cancer cells. #-Time when mice were sacrificed. Day 60 is the end of the experiment, mice were sacrificed and tumors were excised. (B) A comparison between different breast cancer cell lines in tumor growth in nude mice. The mean tumor size in each cell line group was compared. (C) Metastases of breast cancer cell lines in injected nude mice (D) Summary table of tumorigenicity and metastatic potential of breast cancer cell lines.
