An error was noted in Figure 4B following the publication of the article. An image error occurred during the creation of the figure which resulted in the CD34 and CFU-GM columns displaying identical data which was not correct. We are submitting the revised figure which now displays the correct data for the CFU-GM column. This error only involves the display of the data in the figure and does not involve the analysis of the data for the paper. The authors regret this oversight.
