A Population of Multipotent CD34-Positive Adipose Stromal Cells Share Pericyte and Mesenchymal Surface Markers, Reside in a Periendothelial Location, and Stabilize Endothelial Networks

It has been shown that stromal–vascular fraction isolated from adipose tissues contains an abundance of CD34 + cells. Histological analysis of adipose tissue revealed that CD34 + cells are widely distributed among adipocytes and are predominantly associated with vascular structures. The majority of CD34 + cells from freshly isolated stromal–vascular fraction were CD31 − /CD144 − and could be separated from a distinct population of CD34 + /CD31 +...
