Figure 1. Expression of VCAM-1 surface marker in mouse embryonic myocardium.

Figure 1

Immunofluorescence images of tissue cryo-sections showing that VCAM-1 is expressed by the myocardium in embryonic hearts (A–J) and by vascular endothelium in adult hearts (K–M). VCAM-1 co-localizes with cardiac specific cTropT (A) and is situated at the cell surface (E, H). VCAM-1 does not co-localize with endocardial/endothelial specific PECAM-1 in embryonic hearts (A, E). PECAM-1, VCAM-1 or cTropT in separate channels (B–D, F–G, I–J and L–M). Abbreviations: (atr) atria (hep) hepatic primordia (end) endocardium (myo) myocardium (ven) ventricle. Tissue sections: E10.5 (A–D, H–J); E12.5 (E–G); Adult (K–M). Optical sections: E–J.
