Effects of lipoxygenase metabolites of arachidonic acid on the growth of human blood CD34(+) progenitors.
The influence of lipoxygenase metabolites of arachidonic acid on proliferation and differentiation of CD34(+) cells was studied. Their effects on the CFU-GM and BFU-E progenitors were investigated by culture of CD34(+) cells in liquid or semisolid medium. Only 12-HETE (1 microM) stimulated the [(3)H]thymidine as well as BrdU incorporation and increased the number of cell divisions (PKH2 tracking). Addition of 12-HETE and 15-HETE but not of LXA(4), LXB(4), LTB(4), and LTC(4) to liquid cultures of CD34(+) cells for 3 and 8 days reduced in a time-dependent manner the number of CFU-GM and BFU-E. Both HETEs also increased the percentage of glycophorin A(+) cells while they reduced the percentage of CD34(-)/CD33(+) cells after 3 and 5 days of liquid cultures. These results show that HETE treatment stimulates proliferation and accelerates the differentiation of CD34(+) cells, mostly toward the erythroid lineage.
