Fluorescence-activated cell sorting analysis of the cell isolate after bone marrow aspiration and of the cell population for implantation.

aThere were very few observations of CD90+ cells among the CD105+/CD166+ cells directly after isolation, thus a mean value could not be calculated.
MSC, mesenchymal stromal cells.
