Results
Specimen 1C: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: mammary mesenchyme Present 1C Expression distributed throughout mesenchymal tissues surrounding the mammary epithelial rudiment.

Specimen 2A: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: mammary mesenchyme Present Regionally restricted 2A Authors report that expression in concentrically packed mesenchymal cells in the peripheral region of the epithelial knob.

Specimen 3E: embryonic day 17.5 (more )
Structure Level Pattern Image Note
TS25: mammary mesenchyme Present Regionally restricted 3E Expression in thin filaments localized on mesenchymal fibroblasts surrounding mammary epithelial rudiments. Less expression in fat pad precursor tissues.

Specimen 3F: embryonic day 18.5 (more )
Structure Level Pattern Image Note
TS26: mammary mesenchyme Present Regionally restricted 3F Expression in thin filaments localized on mesenchymal fibroblasts surrounding mammary epithelial rudiments. Less expression in fat pad precursor tissues.

Specimen 5C: postnatal newborn (more )
Structure Level Pattern Image Note
TS27: mammary gland connective tissue Present Regionally restricted 5C Expression scattered throughout mesenchymal tissues; fibrillar pattern of expression in fibroblastic mesenchymal cells and associated extracellular matrices.

Specimen 6C: postnatal week 5 (more )
Structure Level Pattern Image Note
TS28: mammary gland connective tissue Present Regionally restricted 6C Strong expression in fibroblastic cells surrounding the flank region of the end bud. Fibrillar expression in septal structures separating the fatty stroma which separates the tree-like pattern of epithelial ducts.
