How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Circulating progenitor cells home to and engraft to sites of ischemia, mediated in part by the adhesion molecule L-selectin; however, accumulation in tissues such as the heart is low. In this study, an acellular collagen-based matrix containing sialyl Lewis(X) (sLe(X)), which binds L-selectin, was developed in order to enhance the endogenous progen...
Objectives: Following a cardiac event, circulating progenitor cells can home and engraft to sites of neovascularization, mediated in part by the adhesion molecule L-selectin; however, accumulation in the heart is low. We developed an acellular matrix containing the oligosac-charide sialyl Lewis X (sLe X ; 0.1mM), which binds L-selectin, in order to...
