Human UCB contains ALDH^br cells. Red cell-depleted UCB mononuclear cells were stained with 1 μM BAAA. (A) The scatter properties of stained UCB. Region R1 defines the SSC^lo population and R2 defines the monocyte population. (B–D) The BAAA staining profile of the total UCB, monocytes, and SSC^lo cells, respectively. The SSC^loALDH^br cells are defined by the M1 cursor in D. In each panel the dotted line is the diethylaminobenzaldehyde-treated negative control and the solid line is the experimental sample. The data are representative of six experiments.
