Figure 4From: Bone marrow derived cells in adult skeletal muscle tissue in humansY chromosome-positive nuclei in endothelial cell. Immunofluorescent staining visualized by fluorescent microscopy shows XY-FISH combined with staining for the endothelial marker CD31 (green). The section was examined with a 100Ă— objective. (A) Y chromosome (bright green, arrow), together with X chromosome (red, arrowhead) inside endothelial cell stained for CD31 (green). Nuclear DNA was counterstained by DAPI. Size bar = 10 ÎĽm. (B) Same image without CD31-staining for better visualization of chromosome staining.Back to article page
