cells were located at the base of the acinar cell and were stellate shaped.
In conclusion, myoepithelial
breast cancer represents a rare group of cancers whose prognosis is not clear.
Canine mammary tumors: a review and consensus of standard guidelines on epithelial and myoepithelial
phenotype markers, HER2, and hormone receptor assessment using immunohistochemistry.
Histologically, it is a basaloid tumor, consisting of ductal epithelial and myoepithelial
cells in different configurations, namely, tubular, cribriform, and solid patterns, each of them usually forming a part of a composite tumor.
The changes observed in [alpha]-SMA, with a lower expression in parotid glands after one episodic ethanol binge or after 1 and 4 weeks of binge drinking in submandibular glands, are directly related to myoepithelial
Classically it is biphasic and is characterized by a mixture of polygonal epithelial and spindle-shaped myoepithelial
elements in a variable background stroma that may be mucoid, myxoid, cartilaginous or hyaline.
Smears were examined for adequacy, morphologic characteristics of ductal epithelial cells (architecture and cytology), presence of myoepithelial
cells, background stromal material and inflammatory cells.
At 15 [micro]M/kg, the basement membrane and myoepithelial
cells appeared normal.
Occasionally, groups of myoepithelial
cells and spicules occur, which are embedded in septal connective tissue (Fig.
14Histologically CS consists of mixed epithelial and mesenchymal elements with epithelial cells arranged in cords and forming tubules with a myoepithelial
layer set in a myxoid or chondroid stroma.
The expression of P-cadherin is restricted only to basal or lower layers of epithelia, including prostate and skin and also to breast myoepithelial
The cells with bilineage potential (stem cells and bilineage progenitors), as well as myoepithelial
-restricted progenitors, share many phenotypic markers with basally located myoepithelial
