In addition, there were no statistical differences among the expression levels of FTL on the membrane of CD15+ cells in the untreated group (0.62 ± 0.58%), the recovered group (0.57 ± 0.66%), the group of low-risk MDS and AA (2.43 ± 2.79%), and the case-control group (0.28 ± 0.22%), P > 0.05 (Figure 4E). Here, FUT4 is linked to myelodysplastic syndrome.
