mammary gland

Any of the milk-producing glands in female mammals, consisting of lobes containing clusters of alveoli with a system of ducts to convey the milk to an external nipple or teat. These glands typically occur in pairs and begin secreting milk when young are born.

1. (Anatomy) any of the milk-producing glands in mammals. In higher mammals each gland consists of a network of tubes and cavities connected to the exterior by a nipple
2. (Zoology) any of the milk-producing glands in mammals. In higher mammals each gland consists of a network of tubes and cavities connected to the exterior by a nipple

any of the accessory reproductive organs of female mammals that occur in pairs on the chest or ventral surface and contain milk-producing lobes with ducts that empty into a nipple.

mam·ma·ry gland

One of the glands in female mammals that produces milk. It is present but undeveloped in the male. In most animals, the gland opens onto the surface by means of a nipple or teat.

It has been previously demonstrated that peptides containing methionine can easily utilize free methionine supplementation for mammary tissue and milk protein synthesis in cultured mammary epithelial cells [22].
That's because intact (unspayed) female dogs have fully developed mammary tissue. A dog spayed prior to sexual maturity (occurs around 6 months old) is at a reduced risk of mammary cancer because the spay removes the ovaries, which produce the estrogen that is significant to the full development of the mammary glands.
Ten mammary tumor specimens and a normal mammary tissue from dogs regardless of age and breed were studied.
A more recent study evaluated the miRNA profile in a canine mammary carcinoma cell line compared with normal canine mammary tissue and observed 291 miRNAs with altered expression; among them, miR-143 and miR-138a showed increased and decreased expression, respectively, in the cell line under study (OSAKI et al., 2016).
Like other female reproductive tissues, many hormones and growth factors influence mammary tissue, with the primary drivers depending on the stage of development.

To confirm this speculation, CYP1A1 expression was first examined in the mammary tissue of bovine with or without mastitis, extracted epithelial cells from these two types of tissues, and treated mammary epithelial cells with LPS in this study.

Endogenous hormonal factors may contribute to development of mammary edema in peripartum condition because several hormones are involved in growth and development of mammary tissue and initiation of milk synthesis (Erb, 1977).
A total of 96 cases were included in this study: 52 in the malignant group (invasive no special type (NST) ductal carcinomas) and 44 in the nonmalignant group (21 cases with lactational change and 23 cases with normal mammary tissue histology).
