PTPRC and differentiated thyroid carcinoma: Tellez et al. [38] used PHH3 to guide annotations of mitotic cells in breast cancer tissue, Bulten et al. used P63 and CK8/18 as the reference standard for a CNN to segment epithelium in prostate cancer [54], and Valkonen et al. [55] automatically transferred CD45 to an H&E slide to segment leukocytes in papillary thyroid carcinoma.
