Fig. 7From: An exploratory study for tuft cells in the breast and their relevance in triple-negative breast cancer: the possible relationship of SOX9Distribution of SOX9-positive cells in the human non-neoplastic breast. SOX9-positive cells are clearly seen in ducts/acini without particular distribution patterns (a, b). Seemingly focal co-expression of POU2F3 (c) and SOX9 (d) is observed (a: H&E staining, b–d: immunohistochemistry)Back to article page
