TGF-α expression in different nontumor tissues around tumor. (a) TGF-α in nontumor tissues around primary lesion of breast cancer with bone metastasis (BMBC) (400x, arrows pointing to TGF-α positive cells); (b) TGF-α in nontumor tissues around primary lesion of breast cancer without bone metastasis (Non-BM-BC) (400x); (c) TGF-α in nontumor tissues around benign breast fibroadenoma (400x); (d) comparison of TGF-α positive cells in nontumor tissues of different groups (total positive cells within 5 random fields). .
