Randomized trial investigates the role of bone marrow monocyte cells in reendothelialization, suggesting new cell therapy strategies.

This research aims to explore how bone marrow-derived monocyte lineage cells assist in reendothelialization after vascular injury.
CD14+ monocytes from peripheral blood were analyzed for their ability to transdifferentiate into endothelial cell-like cells.
Bone marrow-derived CD34-/CD14+ cells were intra-arterially transplanted into balloon-injured arteries of athymic nude rats to assess their functionality in vivo.
Adhesive properties and differentiation were assessed in vitro using MCP-1 and different growth factors.
Bone marrow monocyte lineage cells adhered to injured endothelium and induced significant differentiation into endothelial-like cells.
These cells inhibited neointimal hyperplasia more effectively than CD34+ cells, demonstrating enhanced regenerative potential.
MCP-1 increased adhesive activity of bone marrow monocytes by 2.8-fold on endothelial cells, activating integrin conformation for better adhesion.

Fujiyama et al. (2003) studied this question.
