Stable expression of angiopoietin-1 and other markers by cultured pericytes: phenotypic similarities to a subpopulation of cells in maturing vessels during later stages of angiogenesis in vivo.

Abstract excerpt

Pericytes have been difficult cells to study because they do not maintain their characteristic phenotype in vitro, and they begin to express fibroblast markers after only a few days in culture. We now report methods for the isolation, purification, culture, and repurification of human dermal pericytes from mixed cell populations using an immunoaffinity-magnetic bead approach coupled with the 3G5 IgM monoclonal...
