MSX2 in SK‑BR‑3 Human Cell Line. MSX2 was detected in immersion fixed SK‑BR‑3 human breast cancer cell line using Mouse Anti-Human MSX2 Monoclonal Antibody (Catalog # MAB7917) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

MSX2, also known as HOX-8, is an approximately 35 kDa homeobox transcription factor that is a downstream target of canonical Wnt signaling. MSX2 plays an important role in the development of mineralized tissues including bone, cartilage, and teeth. It is upregulated in atherosclerotic plaques and promotes the calcification of vascular smooth muscle cells during inflammation. MSX2 suppresses the adipocytic differentiation of multipotent mesenchymal cells. MSX2 acts in mammary gland development and the initiation of female fetal germ cell meiosis. It promotes tumorigenesis of breast and pancreatic carcinomas but inhibits the survival and invasiveness of melanoma cells. Human MSX2 contains one homeodomain (aa 143-201). Within aa 1-132, human MSX2 shares 87% aa sequence identity with mouse and rat MSX2.
