Fig. 3From: Heterogeneity of BCSCs contributes to the metastatic organotropism of breast cancer Regulatory networks of BCSCs-related lung metastasis in breast cancer. BCSCs can regulate lung metastasis of breast cancer through various biological processes, including self-renewal, apoptosis, epithelial-mesenchymal transition and immune response. Arrow represents up-regulation while perpendicular line represents down-regulationBack to article page
