holocrine

 [hol´o-krin]
wholly secretory, denoting that type of glandular secretion in which the entire secreting cell, along with its accumulated secretion, forms the secreted matter of the gland, as in the sebaceous glands. See also apocrine and merocrine.

hol·o·crine gland

a gland the secretion of which consists of disintegrated cells of the gland itself, for example, a sebaceous gland, in contrast to a merocrine gland.

holocrine

(hŏl′ə-krĭn, -krīn′, -krēn′, hō′lə-)
adj.
Of or relating to a gland whose output consists of disintegrated secretory cells along with the secretory product itself.

hol·o·crine gland

(hol'ō-krin gland)
A gland with secretion that consists of disintegrated cells of the gland itself, e.g., a sebaceous gland, in contrast to a merocrine gland.

holocrine

Pertaining to a gland whose secretion is a breakdown product of the gland's own lining cells. A sebaceous gland is a holocrine gland.

holocrine

  1. (of a form of cell digestion, particularly in insects) characterized by self-disintegration to produce the digestive fluid.
  2. (of gland secretion) characterized by self-disintegration in releasing its product, as in sebaceous glands.

cribrarius the dissolution of the sperm plug was associated with desquamation cells producing holocrine secretions.
The dense layer became thinner, although desquamation continued (holocrine secretion).
Furthermore, although sebum secretion is generally considered to be regulated by a holocrine mechanism, which may be associated with sebaceous apoptosis [44], nobiletin-enhanced sebum excretion is independent of the apoptosis of differentiated hamster sebocytes [22].
In general, exocrine glands are classified into unicellular and multicellular glands according to the number of composition cells, and they can be divided further into holocrine glands and merocrine glands depending on their patterns of secretion (Kurosumi et al.
It is a holocrine gland enclosed in a connective tissue capsule made up of glandular acini that deposit their oil secretion into a common collector tube ending in a variable number of pores, most usually two.
The disorganized nature of this epithelium, the poorly defined cell membranes, and the cellular debris in the lumen are all consistent with holocrine secretion, as suggested by previous authors (Halstead, 1988; see also dos Santos et al., 2000).
