   • 1982, Vladimir Evgen?evich Sokolov, Mammal Skin, University of California Press, page 20,

     Merocrine cells have several full secretion cycles — the merocrine secretion cell does not die when it secretes into the lumen of the gland.

   • 2011, S. M. Kisia, Vertebrates: Structures and Functions, page 53,

     Secretions from glands are produced by merocrine, apocrine and holocrine modes of secretion (Fig. 3.4). In merocrine secretion, membrane bound secretory vesicles are formed and accumulate below the free surface of the cell. […] There is no loss of cytoplasm in merocrine secretion.

   • 2003, Marton Lanyi, Mammography: Diagnosis and Morphological Analysis, page 64,

     Lobular cysts as well as micro- and macrocysts are very often lined to a variable extent by apocrine epithelium. Pathologists call this condition apocrine metaplasia, meaning a transformation of the normal epithelial cells into sweat-gland-like cells similar to those found in the apocrine glands of the vulva, eyelid, and external auditory canal.

   • 2011, Jivko A. Kamarashev, 3.2.1: Tumours with Apocrine and Eccrine Differentiation, Reinhard Dummer, Mark R. Pittelkow, Keiji Iwatsuki, Adèle Green, Nagwa M. Elwan (editors), Skin Cancer - A World-Wide Perspective, page 128,
