<i>Ex vivo</i> expansion of CB CD34⁺ cells over 14 days.

<p>The cells were stained with PE-conjugated mAb to CD34 and FITC-conjugated mAb to CD38, and analyzed by flow cytometry. Values indicate the fold increase compared with the initial number of cells (2.0×10⁴/well).The results are given as mean ± standard deviation (SD) (<i>n</i> = 6). ^*p<0. 05 versus the CTRL cells (Student’s <i>t</i>-test).
