Figure 4From: Triple-negative vimentin-positive heterogeneous feline mammary carcinomas as a potential comparative model for breast cancerPotential localization of mammary cell lineages and associated tumour origin. A) Hypothetical distribution of cell subtypes within the feline mammary gland according to the immunohistochemical analyses for cytoplasmic filaments and associated presumptive cell/site of origin of feline mammary tumors. B) Hypothetical lineage differentiation of feline mammary gland cell subtypes. (DT, ductal tumors; IDP, intraductal papillary tumors; ER, estrogen receptor alpha; PR, progesterone receptor; CK, cytokeratin; vim, vimentin; CALP, calponin; SMA, alpha-smooth muscle actin).Back to article page
