Table 1.

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

Surface Markers	Isolation % of Cells, Mean (SD)	Implantation % of Cells, Mean (SD)
Surface Markers Used for Hematopoietic Lineage Characterization
CD 34+/CD 45−	1.8 (1.7)	0.6 (0.5)
CD 45+/CD 34−	42.8 (13.1)	0.4 (0.3)
CD34+/CD45+	0.7 (0.8)	0.1 (0.1)
Surface Markers Used for MSC Lineage Characterization
CD 105+/CD 166−	1.6 (2.3)	5.0 (8.7)
CD 166+/CD 105−	0.2 (0.4)	0.3 (0.4)
CD105+/CD 166+	0.9 (2.2)	58.8 (16.4)
CD 90+	0.4 (0.5)	71.3 (12.8)
CD 90+ of CD105+/CD166+	ND a	98.1 (1.1)

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.
