Results are presented as median values (range)

Tot CD34+, total CD34+ hematopoietic progenitor cells; CD34 + CD19-, fraction of CD34 + CD19- cells (out of total CD34+ cells); CD34 + CD19+, fraction of CD34 + CD19+ cells (out of total CD34+ cells); Ratio, CD34 + CD19-/CD34 + CD19+ cellular fraction ratio

The Kruskal-Wallis statistic test with pairwise comparisons was used for this analysis (no significant results)
