1. Caracterização anatomopatológica e imuno-histoquímica dos tumores das glândulas cutâneas em cães
RESUMO O presente estudo objetivou caracterizar os aspectos anatomopatológicos e imuno-histoquímicos dos tumores das glândulas cutâneas em cães. A caracterização morfológica seguiu a classificação atualizada da Organização Mundial de Saúde. Para a caracterização imuno-histoquímica, utilizaram-se anticorpos monoclonais primários anti-citoquer

2. The accuracy of fine-needle aspiration cytology for diagnosis of parotid gland masses: a clinicopathological study of 114 patients
ABSTRACT Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis

3. The effects of antidepressants and pilocarpine on rat parotid glands: an immunohistochemical study
OBJECTIVES: To evaluate the effects of antidepressants and pilocarpine on the quantity of myoepithelial cells and on the proliferation index of the epithelial cells of rat parotid glands. INTRODUCTION: Hyposalivation, xerostomia, and alterations in saliva composition are important clinical side effects related to the use of antidepressants. METHODS: Ninety m

4. FGF-2, TGFβ-1, PDGF-A and respective receptors expression in pleomorphic adenoma myoepithelial cells: an in vivo and in vitro study
Myoepithelial cells have an important role in salivary gland tumor development, contributing to a low grade of aggressiveness of these tumors. Normal myoepithelial cells are known by their suppressor function presenting increased expression of extracellular matrix genes and protease inhibitors. The importance of stromal cells and growth factors during tumor

5. EXPRESSION OF P63 AND P53 IN CANINE MAMMARY MIXED TUMORS / EXPRESSÃO DE P63 E P53 EM TUMORES MAMÁRIOS MISTOS DE CADELAS
A proteína p63 é expressa no núcleo das células mioepiteliais da mama e apresenta funções sinérgicas ou antagonistas com a proteína de supressão tumoral p53. A expressão imuno-histoquímica de p63 foi estudada para acessar o papel das células mioepiteliais na histogênese dos tumores mistos. Adicionalmente, avaliou-se a possível relação entre e

6. Ultraestructura de los acinos sudoríparos de las glándulas pelvianas de Chaetophractus villosus (Mammalia, Dasypodidae)
The acini of pelvian glands of Chaetophractus villosus (Desmarest, 1804) consisted of an inner layer of secretory cells and an outer layer of myoepithelial cells. Secretory cells have numerous secretory vacuoles. The secretion is released by exocytosis. Myoepithelial cells have numerous myofilaments that occupy much of the cytoplasm. There is a third cell ty

7. The importance of being a myoepithelial cell
The mammary myoepithelial cell was named the 'Cinderella of mammary cell biology' in light of the earlier focus on the luminal cell. Mammary myoepithelial cells have recently been described as 'natural tumour suppressors'. We now need to understand more about their origin and to reconsider their place in the complex process of mammary morphogenesis. In the p

8. Myoepithelial carcinoma (malignant myoepithelioma) of the parotid gland arising in a pleomorphic adenoma.
A myoepithelial carcinoma, a rare malignant salivary gland neoplasm, arose in a pleomorphic adenoma of the parotid gland. The initial tumour was a pleomorphic adenoma with epithelial and myoepithelial elements. Subsequently the tumour recurred twice and was characterised by invasion of the mandible. Histological examination of the second recurrence showed a

9. Increased abundance of a normal cell mRNA sequence accompanies the conversion of rat mammary cuboidal epithelial cells to elongated myoepithelial-like cells in culture.
Rat mammary cuboidal epithelial cell lines in culture convert to elongated myoepithelial-like cells. This conversion is accompanied by the appearance of a 9,000 molecular weight acidic polypeptide (p9ka), abundant in the elongated convertants, but which is hardly detectable in the cuboidal epithelial cells. A cDNA library corresponding to a low-molecular-wei

10. Epithelial myoepithelial tumour of the tracheal gland.
A case of epithelial myoepithelial tumour originating from the tracheal gland in a 57 year old woman is described. The tumour was removed by segmental tracheal resection and end-to-end anastomosis. Histologically, the tumour comprised clear cells and presented a monophasic pattern. Immunohistochemical analysis showed that the tumour cells were positive for b

11. Clear cell mammary malignant myoepithelioma with abundant glycogens.
Malignant myoepithelioma (myoepithelial carcinoma) of the breast is extremely rare. A case is reported of a 46 year old female with clear cell mammary malignant myoepithelioma that, on histological examination, was glycogen abundant clear cell carcinoma. Immunohistochemically, the clear cells showed myoepithelial differentiation--that is, they were a smooth

12. Identification of mouse mammary epithelial cells by immunofluorescence with rabbit and guinea pig antikeratin antisera.
Few markers are available to identify the three types of mammary epithelial cells--ductal, alveolar, and myoepithelial--especially in pathological conditions and in cell cultures. We have used antisera to human keratins in immunofluorescence to facilitate the identification of the three mouse mammary epithelial cell types. In frozen tissue sections and prima
