Preferred Label : mammary placode;
Uberon definition : The mammary placode is a transient lens shaped structure that will give rise to the
mammary bud proper[GO].;
Uberon related term : mammary anlage;
Uberon Taxon note : in mouse, five pairs of symmetrically positioned mammary placodes (three thoracic
and two inguinal) form at reproducible locations along the mammary line at E11.5;
the individual pairs develop asynchronously and in a distinct order; pair 3 is first,
followed by pair 4, then by pairs 1 and 5 (which develop together), and finally by
pair 2; the orientation of placodal cells is not uniform, suggesting that placodes
are formed by migration of cells from the mammary line; between E11.5 and E12.5, each
mammary placode expands and invaginates into the underlying mesenchyme to form an
early bulb-shaped mammary bud[MP];
