Mesenchymal Stem Cells Subpopulations: Application for Orthopedic Regenerative Medicine

Figure 1

Pericytes and adventitial cells associated with skeletal muscle microvessels. A scheme showing the MSC subpopulations present in the three structural layers of blood vessels: pericytes (green) from media, adventitial cells (yellow) from adventitia, and myogenic endothelial cells from intima. Illustration of the phenotype of the corresponding cells: pericytes (CD45⁻/CD146⁺/CD34⁻) and adventitial cells (CD45⁻/CD146⁻/CD34⁺).
