The chemotactic activity of beta-carotene in endothelial cell progenitors and human umbilical vein endothelial cells: A microarray analysis.

Objectives: Endothelial cells and their progenitors play an important role in angiogenesis that is essential for organogenesis and tissue remodelling, as well as for inflammatory responses and carcinogenesis in all periods of life. In the present study, the authors concentrated on the direct effect of beta-carotene (BC) on human umbilical cord-originated endothelial progenitor cells and human umbilical vein endothelial cells.

Methods: BC uptake was measured using high-performance liquid chromatography.
