editor note

Mammary glands develop by similar mechanisms, and there is an argument for including them here (e.g. http://www.ncbi.nlm.nih.gov/pubmed/20484386), but these structures do not fit the current definition (lactiferous glands are part of the integumentary system in FMA). Note the FMA class is a subdivision of epidermis, which may be too restrictive for our purposes here.
