Abstract:
Objective To explore the expansion and differentiation of bone marrow endothelial progenitor cells in vitro. Methods Rabbit bone marrow mononuclear cells were isolated by gradient density centrifugation.Attached cells were cultured and in endothelial cell growth supplement(ECGS) from bovine pituitary.Cell multiplication was observed,and their biological characteristics were detected. Results The number of attached cells increased 5～8 fold with each expanded.Cobblestone like structure was observed when the cells lined in single layer.Expanded cells expressed von Willebrand factor(vWF) and could ingest Dil acLDL. ConclusionEndothelial progenitor cells,which exist within adult bone marrow,have the potential to be expanded and differentiated when stimulated by ECGS in vitro.
