Interacting cytokines regulate in vitro human megakaryocytopoiesis.
The effects of hematopoietic growth factors on in vitro human megakaryocytopoiesis were studied using a serum-depleted culture system. Both recombinant interleukin-3 (r-IL-3) and recombinant granulocyte-macrophage colony-stimulating factor (rGM-CSF) increased megakaryocyte (MK) colony formation (P less than .01) above that observed in baseline cultures. Recombinant interleukin-4 (rIL-4) and int...
متن کاملInterleukin-11 enhances human megakaryocytopoiesis in vitro.
We investigated the effect of recombinant human interleukin-11 (rhIL-11) on human megakaryocytopoiesis. Nonadherent and T-cell-depleted human bone marrow (BM) mononuclear cells were cultured in a serum-free agar culture system. rhIL-11 alone did not stimulate the growth of human megakaryocyte colonies. However, when rhIL-11 was combined with optimal or suboptimal doses of rhIL-3, the number and...

متن کاملChemokine regulation of human megakaryocytopoiesis.
We have previously shown that platelet factor 4 (PF4), a platelet-specific CXC chemokine, can directly and specifically inhibit human megakaryocyte colony formation. We therefore hypothesized that PF4 might function as a negative autocrine regulator of megakaryocytopoiesis. Herein we present additional studies characterizing the inhibitory effect of CXC chemokines on human megakaryocyte develop...
متن کاملMicroRNA fingerprints during human megakaryocytopoiesis.
microRNAs are a highly conserved class of noncoding RNAs with important regulatory functions in proliferation, apoptosis, development, and differentiation. To discover novel regulatory pathways during megakaryocytic differentiation, we performed microRNA expression profiling of in vitro-differentiated megakaryocytes derived from CD34(+) hematopoietic progenitors. The main finding was down-regul...
