    Lonza amaxa human cd34 cell nucleofector kit
    (a) Isolated HPC <t>(CD34</t> + Lin − ) cells were cultured in IL-15-supplemented media, and the culture media was replaced every 48 h. The expression of CD56 as an NK cell surface marker was analyzed using FACS. (b) The kinetics of the mRNA expression of Id2, NKp30, NKG2D and Granzyme B were analyzed by real-time qPCR. (c) Stage 2 progenitors <t>(CD34</t> + CD117 + CD94 − ) and stage 3 progenitors (CD34 − CD117 + CD94 − ) were isolated from UCB by flow sorting. The mRNA expression of IL2Rγ, NKp46 and NKG2D were analyzed by real-time qPCR. (d) A dendrogram of hierarchical clustering revealed genes that were altered more than 2-fold in 7d- and 14-d (mNK) cultured NK cell compared with 1 d-cultured cells. (E-F) The bar graphs represent the top seven functional categories of upregulated (e) or downregulated (f) genes according to the gene ontology analysis (as determined by DAVID, as described in the Methods). The data are representative of three independent experiments performed using three different UCB samples and represent the mean values ± S.E.M. of duplicates.

    (a) Negatively correlated miRNA-mRNA interactions were visualized as a network using Magia (miRNAs and genes integrated analysis web-based tool). This network provides for the first time a theoretical outline of the concerted action of regulating miRNAs (red triangles) and their potential target mRNAs (green circles). (b) Isolated HPC (CD34 + Lin − ) cells were cultured as described in the Materials and Methods. After being cultured in IL-15-supplemented media, the cells were collected at the indicated time intervals. The expression of miR-143, miR-223, miR-150 and miR-583 was analyzed by real-time qPCR. The data are representative of five independent experiments performed using two different UCB samples and represent the mean values ± S.E.M. of duplicates.
