Matrilin-1 in Human Mesenchymal Stem Cells. Matrilin-1 was detected in immersion fixed human mesenchymal stem cells differentiated into chondrocytes using Mouse Anti-Human Matrilin-1 Monoclonal Antibody (Catalog # MAB7878) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cartilage matrix. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Matrilin-1, also known as Cartilage Matrix Protein (CMP) is a 50-60 kDa extracellular matrix protein that belongs to the superfamily of von Willebrand factor A (VWA) containing proteins. It is primarily expressed in cartilage and functions as a bridging component between proteins of the collagenous matrix. Mature human Matrilin-1 contains two VWA domains that flank one EGF-like repeat, followed by a C-terminal coiled coil domain. The Matrilins differ in the number of VWA domains (one or two) and EGF-like repeats (one, three, four, or ten) they contain. Human Matrilin-1 shares 91% aa sequence identity with human and rat Matrilin-1. The coiled coil domain of Matrilin-1 mediates disulfide-linked homo-trimer formation. It can also assemble into hetero-oligomers with Matrilin-2, -3, and -4.
