miR-184 in UCB CD4⁺ T cells. (A) miR-184 was quantified in AB (n = 8) and UCB (n = 10) samples by qRT-PCR as described. P value obtained from unpaired, 2-tailed Student t test. (B) miR-184 was quantified in UCB CD4⁺ T cells stimulated in vitro as described for the designated time points (representative of 3 experiments). (C) miR-184 was quantified in AB CD4⁺ T cells stimulated in vitro as described for the designated time points (representative of 2 experiments).
