FIG. 1.

Immunohistochemical phenotype of ovine bone marrow–derived mesenchymal stem cells (oMSCs). Isolated adherent ovine MSCs show positive signals for CD166, CD44, CD29, and STRO-4 in flowcytometry analysis (a). No signal was detected for CD31 (a; IgG1 served as isotype control). In immunohistochemistry (b–g), oMSCs show expression of myogenic markers (c–e), including alpha-smooth muscle actin (α-SMA) (c, d) and vimentin (e). Also stainings for common ovine stem cell markers (b), including CD29, CD166, STRO-4, and CD44, are positive (b; scale bar=16 μm). No positive signal was found for CD31 (b), IgG1-isotype control, Desmin (f), and von Willebrand factor (vWF) (g). Color images available online at www.liebertpub.com/tec
