Research Abstract

We generated platelets (PLT) from cord blood (CB) CD34^+ cells employing a three-phase culture system. We first cultured 500 CB CD34^+ cells on telomerase gene-transduced human stromal cells (hTERT stroma) in serum-free medium supplemented with stem cell factor (SCF), Flt-3/Flk-2 ligand (FL) and thrombopoietin (TPO) for 14 days. We then transferred the cells to hTERT stroma and cultured for another 14 days with fresh medium containing interleukin-11 (IL-11) in addition to the original cytokine cocktail. Subsequently, we cultured the cells in a liquid culture medium containing SCF, FL, TPO and IL-11 for another 5 days to recover PLT fractions from the supernatant, which were then gel filtered to purify the PLT. The calculated yield of PLT from 1.0 unit CB (5x10^6 CD34+ cells) was 1.26 x10^<11> - 1.68 x10^<11> PLT. These numbers of PLT are equivalent to 2.5-3.4 units of random donor-derived PLT or 2/5-6/10 of a single apheresis PLT. The CB-derived PLT exhibited features quite similar to those from peripheral blood in morphology, as revealed by electron micrographs, and in function, as revealed by fibrinogen/ADP aggregation, with the appearance of P-selectin and activated glycoprotein IIb-IIIa antigens. Thus this culture system may be applicable for large scale generation of PLT for future clinical usage.
