(Submitter supplied) Osteolineage cell-derived extracellular vesicles (EVs) play a regulatory role in hematopoiesis and have been shown to promote the ex vivo expansion of human hematopoietic stem and progenitor cells (HSPCs). Here, we demonstrate that EVs from different human osteolineage sources do not have the same HSPC expansion promoting potential. Comparison of stimulatory and non-stimulatory osteolineage EVs by next-generation sequencing and mass spectrometry analyses revealed distinct microRNA (miRNA) and protein signatures identifying EV-derived candidate regulators of ex vivo HSPC expansion. more...

(Submitter supplied) Recently, we and others have illustrated that extracellular vesicles (EVs) have the potential to support hematopoietic stem and progenitor cell (HSPC) expansion; however, the mechanism and processes responsible for the intercellular communication by EVs are still unknown. In the current study, we investigate whether primary human bone marrow derived mesenchymal stromal cells (BMSC) EVs isolated from two different origins, fetal (fEV) and adult (aEV) tissue, can increase the relative low number of HSPCs found in umbilical cord blood (UCB) and which EV-derived components are responsible for ex vivo HSPC expansion. more...

(Submitter supplied) Hematopoietic progenitor and stem cells from bone marrow have been sorted by FACS (LSK, Lineage -, Sca1 + and cKit +) and co-culture during 18h without cytokines with or without extracellular vesicles (EV) secreted by AFT stromal cells. We used microarray to detail the modification of gene expression level of LSK cells after contact with AFT Evs

(Submitter supplied) Acute myeloid leukemia (AML) is an aggressive and heterogeneous clonal disorder of hematopoietic stem/progenitor cells (HSPCs). It is not well known how leukemia cells alter hematopoiesis promoting tumor growth and leukemic niche formation. In this study, we investigated how AML deregulates the hematopoietic process of HSPCs through the release of extracellular vesicles (EVs). First, we found that AML cells released a heterogeneous population of EVs (AML-EVs) containing microRNAs involved in AML pathogenesis. more...

(Submitter supplied) In this study, we present the comparative transcriptome analysis of human osteoblasts and their corresponding EVs using next-generation sequencing. We demonstrate that osteoblast-EVs are specifically depleted of cellular mRNAs that encode proteins involved in basic cellular activities, such as cytoskeletal functions, cell survival and apoptosis. In contrast, EVs are significantly enriched with 254 mRNAs that are associated with protein translation and RNA processing. more...

(Submitter supplied) Intercellular communication is essential in bone remodelling to ensure that new bone is formed with only temporary bone loss. Monocytes and osteoclasts actively take part in controlling bone remodelling by providing signals that promote osteogenic differentiation of mesenchymal stem/stromal cells (MSCs). Extracellular vesicles (EVs) have attracted attention as regulators of bone remodelling. EVs facilitate intercellular communication by transferring a complex cargo of biologically active molecules to target cells. more...

(Submitter supplied) The derivation of functional, transplantable HSCs from an pluripotent stem cells in vitro holds great promise for clinical therapies, but is unachieved. In order to achieve full functionality of HSCs, it is vital to determine the extent to which PSCs can currently be differentiated to the HSC program in vitro and identify the remaining dysregulated genetic pathways. Microarrays were used to compare the transcritomes of ESC-derived immunophenotypic HSPCs to endogenous HSPCs from various stages of development to determine the programs important for human HSC development and function, and which programs were lacking in ESC-derived hematopoietic cells.
