Figure 4. Siglec-9 defines a subset of NK cells with a more mature phenotype, yet similar telomere length, present in adult and cord blood.

Figure 4

(A) Flow cytometry for surface expression of adhesion and activation markers. Shown are frequency and GMFI ratio of specific staining to isotype-matched control. (B) Telomere length analysis of different NK cell subsets from 3 healthy donors (HD). 50th percentile is shown as lines within boxes and numerals; upper and lower margins of the boxes denote 25th and 75th percentile; whiskers denote 5th and 95th percentile. (C and D) Siglec-7 and -9 expression among NK cell subsets in adult peripheral blood (PB; n = 14 [Siglec-7], 27 [Siglec-9]) and cord blood (n = 9). *P < 0.05, **P < 0.005, ***P < 0.001, Student’s t test.
