The mammary glands of cows abundantly display receptors for circulating avian H5 viruses. [PDF]
J VirolInfluenza A viruses (IAVs) from the H5N1 2.3.4.4b clade are circulating in dairy farms in the USA.; ruminants were presumed not to be hosts for IAVs. Previously, IAV-positive mammalian species were hunters and scavengers, possibly getting infected while ...

The Mammary Glands of Macaques [PDF]
Toxicologic Pathology, 2008 This review describes the normal biology and physiology of the mammary gland in macaques, including the typical histologic appearance across the life span (development, reproductive maturity, lactation, and senescence). The molecular events regulating breast morphogenesis are described, as well as systemic and local hormonal regulators of mammary gland

The Mammary Gland: Basic Structure and Molecular Signaling during Development
International Journal of Molecular Sciences, 2022 The mammary gland is a compound, branched tubuloalveolar structure and a major characteristic of mammals. The mammary gland has evolved from epidermal apocrine glands, the skin glands as an accessory reproductive organ to support postnatal survival of ...

Mammary gland development [PDF]
WIREs Developmental Biology, 2012 AbstractThe mammary gland develops through several distinct stages. The first transpires in the embryo as the ectoderm forms a mammary line that resolves into placodes. Regulated by epithelial–mesenchymal interactions, the placodes descend into the underlying mesenchyme and produce the rudimentary ductal structure of the gland present at birth ...

Environmental Health Perspectives, 1996 Determining how findings of chemically induced carcinogenic effects in rodents can properly be interpreted for human health poses a continuing challenge to the risk assessment community. One approach begins by comparing and contrasting carcinogenic process in rodents and humans, identifying biologically significant similarities and differences and gaps

Development of the mammary gland [PDF]
Reproduction, 1982 Introduction The first obvious statement is that the mammary gland is an intriguing structure, and that its development is one of the most fascinating aspects. During the lifetime of the animal the mammary gland probably undergoes more and greater changes in size, structure, composition and activity than any ...

Fetal-derived macrophages dominate in adult mammary glands
Nature Communications, 2019 Macrophages serve multiple functions including immune regulation, morphogenesis, tissue homeostasis and healing reactions. The current paradigm holds that mammary gland macrophages first arise postnatally during the prepubertal period from the bone ...

Differential roles of ERα and ERβ in normal and neoplastic development in the mouse mammary gland.
PLoS ONE, 2014 The present experiments were performed to determine the roles of estrogen receptors α and β (ERα and ERβ) in normal and neoplastic development in the mouse mammary gland.
