Are Mesenchymal Cells Indeed Pluripotent Stem Cells or Just Stromal Cells? OCT-4 and VSELs Biology Has Led to Better Understanding

<table>Bovine bone marrow culture to propagate mesenchymal cells. Note that the culture comprises a subpopulation of spherical cells along with the MSCs.  These small round cells are possibly the VSELs.</table>
