Expression of vascular cell adhesion molecule-1 indicates the differentiation potential of human bone marrow stromal cells.
Bone marrow stromal cells (BMSCs) are a mixture of cells differing in differentiation potential including mesenchymal stem cells, and so far no CD antigens were found to be predictable for the differentiation property of each BMSC. Here we attempted to isolate differentiation-associated CD antigens using 100 immortalized human BMSC (ihBMSC) clones. Among 13 CD antigens analyzed, only CD106/Vascular cell adhesion molecule-1 (VCAM-1) showed a clear correlation with the differentiation potential of each clone; CD106-positive ihBMSC clones were less osteogenic and more adipogenic than CD106-negative clones. This association was confirmed in primary BMSCs sorted by CD106, showing that the CD106-positive fraction contained less osteogenic and more adipogenic cells than the CD106-positive fraction. The evaluation of CD106 fraction of BMSC strains in early passages predicted clearly the osteogenic and adipogenic potential after in vitro induction of differentiation, indicating the usefulness of CD106 as a differentiation-predicting marker of BMSC.
