Indirect Immunofluorescence on Frozen Sections of Mouse Mammary Gland
Published on: December 1, 2015
Abstract:
3 groups are distinguished among 219 cases of the breast carcinoma with mucus formation: one-component colloid carcinoma, combined colloid carcinoma and signet ring cell carcinoma. Morphological features and prognosis for each group are listed. One-component colloid carcinoma has the most favourable prognosis: incidence of distant metastases 15% versus 27% and 33% in combined colloid and signet ring cell carcinoma, respectively. Signet ring cell carcinoma should obviously be regarded as a variant of invasive lobular carcinoma.

The Mammary Glands
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...
