Expression of class II beta tubulin by proliferative myoepithelial cells
in canine mammary mixed tumors.
are present in the normal mammary duct system and are often prominent in benign lesions, such as usual ductal hyperplasia, sclerosing adenosis, and intraductal papilloma.
To ascertain the presence of invasion in papillary tumors, the presence or absence of myoepithelial cells
at the periphery of the tumor has been routinely used by pathologists.
CD109, a new marker for myoepithelial cells
of mammary, salivary, and lacrimal glands and prostate basal cells.
are ectodermally derived contractile cells that act as smooth muscle cells.
14) This cell population was able to regenerate itself, myoepithelial cells
, and to form terminal duct lobular units.
Savera et al51 demonstrated that there is really no best single specific immunohistochemical marker for a myoepithelial cell
The electron microscopy: In the control group, the basement membrane was observed with myoepithelial cells
The cells with bilineage potential (stem cells and bilineage progenitors), as well as myoepithelial-restricted progenitors, share many phenotypic markers with basally located myoepithelial cells
If those myoepithelial cells
fall down on the job, the cancer cells can break out and form dangerous tumors.
Immunohistochemically, most cells stained positive for p63, and smooth muscle actin highlighted the myoepithelial cells
within the lesion.
111) Histopathologically, the tumor contains a mixture of epithelial and myoepithelial cells
associated with a myxoid or cartilaginous stroma.
