Research Abstract

To investigate aging of human hematopoietic stem cells, we evaluated the expression levels The median age of the donors was 21 y(range 0.2-44y). The purity of CD34-positive cells was greater than 90%. Both target genes were quantitatively detected in all samples. There was an inverse correlation between the expression level of ikzf1 and the donor's age(r=-0.358, p=0.032). In contrast, there was no correlation between the expression level of cebpa and the donor's age. From the data, the mRNA level of ikzf1 in purified CD34-positive cells may reflect the age of HSCs in human bone marrow.
