The expression levels of FTL on the membrane of CD34+ BM cells in the untreated group (11.61 ± 3.03%) were significantly higher than that of the recovered group (0.71 ± 0.86%, P < 0.05), the group of AA and low-risk MDS (3.88 ± 3.84%, P < 0.05), and the case-control group (1.39 ± 2.26%, P < 0.05). Here, CD34 is linked to myelodysplastic syndrome.
