Developmental Potential

While hematopoietic stem cells from adult and fetal stages of murine development are capable of long term reconstitution of all mature blood lineages in vivo, embryonic hematopoietic stem cell repopulation in vivo has proved difficult. It is thought that there are many fewer hematopoietic stem cells in the embryo than in the fetal/adult stages of mouse development and that these cells possess a different developmental potential. One source of such cells are embryonic stem (ES) cells which can differentiate into most mature blood lineages in vitro. We have therefore used transplantation of differentiated ES cells to assess the hematopoietic potential of embryonic hematopoietic cells in vivo. We demonstrate here that precursors obtained from in vitro cultures of normal ES cells can contribute only to restricted and limited hematopoiesis in a mouse without leading to tumour formation. Repopulation occurs for greater than 6.5 months at levels ranging from 0.1% to 6% in B and T cell lineages in peripheral blood. In contrast to in vitro colony data demonstrating the myeloid lineage developmental potential of ES cells, no donor-derived myeloid repopulation was observed in CFU-S assays and no macrophage and mast cells were found in long term repopulated recipients. Thus, the hematopoietic potential of ES cells in vivo is limited to low levels of repopulation and is restricted to the lymphoid lineage.

We previously reported that long-lasting in vitro hematopoiesis could be achieved using the cells differentiated from primate embryonic stem (ES) cells. Thus, we speculated that hematopoietic stem cells differentiated from ES cells could sustain long-lasting in vitro hematopoiesis. To test this hypothesis, we investigated whether human hematopoietic stem cells could similarly sustain long-lasting in vitro hematopoiesis in the same culture system. Although the results varied between experiments, presumably due to differences in the quality of each hematopoietic stem cell sample, long-lasting in vitro hematopoiesis was observed to last up to nine months. Furthermore, an in vivo analysis in which cultured cells were transplanted into immunodeficient mice indicated that even after several months of culture, hematopoietic stem cells were still present in the cultured cells. To the best of our knowledge, this is the first report to show that human hematopoietic stem cells can survive in vitro for several months.

Hematopoietic Activity

Abstract Mounting evidence accumulates that bone marrow (BM) contains a population of pluripotent stem cells (PSC) that give rise to long-term repopulating hematopoietic stem cells (HSC). Recently we identified in murine BM a homogenous population of rare (∼0.01% of BMMNC) and very small (2–4 μm) Sca-1+ lin− CD45− cells that express by RQ-PCR and immunhistochemistry markers of PSC such as SSEA-1, Oct-4, Nanog and Rex-1 and highly express Rif-1 telomerase protein (Leukemia2006;20,857–869). Direct electronmicroscopical analysis revealed that these cells display several features typical for primary epiblast-derived embryonic stem cells such as i) a large nuclei surrounded by a narrow rim of cytoplasm, and ii) open-type chromatin (euchromatin). In co-cultures with C2C12 murine sarcoma supportive feeder-layer, these cells grow spheres that are composed of immature CXCR4+SSEA-1+Oct-4+ cells that have large nuclei containing euchromatin and, if plated into cultures promoting tissue differentiation, show pluripotency and expand into cells from all three germ-cell layers. Based on this, we called them very small embryonic like (VSEL) stem cells. However, VSEL isolated freshly from the BM do not posses immediate hematopoietic activity - they neither grow hematopoietic colonies nor radioprotect lethally irradiated recipients. Recently, however, we noticed that if plated over supportive OP9 cell line, these CD45− VSEL give rise to colonies of CD45+CD41+Gr-1−Ter119− cells where their phenotype resembles those of the earliest hematopoietic cells that are derived in vitro from established embryonic cell lines. This hematopoietic differentiation of VSEL was accompanied by upregulation of mRNA for several genes regulating hematopoiesis (e.g. PU-1, c-myb, LMO2, Ikaros). More importantly, the CD45+CD41−Gr-1−Ter119− cells expanded from VSEL isolated from GFP+ mice if transplanted into wild-type animals protected them from lethal irradiation and differentiated in vivo into all major hematopoietic lineages (e.g., Gr-1+, B220+ and CD3+ cells). This hematopoietic activity was maintained after transplantation into secondary recipients. Based on this, we postulate that i) VSEL are PSC that give rise to HSC and ii) that CD45+ cells may derive from a CD45− population. Thus we propose that VSEL are a population of BM-residing PSC that may give rise to long-term engrafting hematopoietic stem cells.

Induced Stress

: In contrast to their almost unlimited potential for expansion in vivo and despite years of dedicated research and optimization of expansion protocols, the expansion of Hematopoietic Stem Cells (HSCs) in vitro remains remarkably limited. Increased understanding of the mechanisms that are involved in maintenance, expansion and differentiation of HSCs will enable the development of better protocols for expansion of HSCs. This will allow procurement of HSCs with long-term engraftment potential and a better understanding of the effects of the external influences in and on the hematopoietic niche that may affect HSC function. During collection and culture of HSCs, the cells are exposed to suboptimal conditions that may induce different levels of stress and ultimately affect their self-renewal, differentiation and long-term engraftment potential. Some of these stress factors include normoxia, oxidative stress, extra-physiologic oxygen shock/stress (EPHOSS), endoplasmic reticulum (ER) stress, replicative stress, and stress related to DNA damage. Coping with these stress factors may help reduce the negative effects of cell culture on HSC potential, provide a better understanding of the true impact of certain treatments in the absence of confounding stress factors. This may facilitate the development of better ex vivo expansion protocols of HSCs with long-term engraftment potential without induction of stem cell exhaustion by cellular senescence or loss of cell viability. This review summarizes some of available strategies that may be used to protect HSCs from culture-induced stress conditions.

Abstract Mobilized peripheral blood hematopoietic stem cells (PBSCs) demonstrate accelerated engraftment compared with bone marrow; however, mechanisms responsible for enhanced engraftment remain unknown. PBSCs mobilized by GROβ (GROβΔ4/CXCL2Δ4) or the combination of GROβΔ4 plus granulocyte colony-stimulating factor (G-CSF) restore neutrophil and platelet recovery faster than G-CSF–mobilized PBSCs. To determine mechanisms responsible for faster hematopoietic recovery, we characterized immunophenotype and function of the GROβ-mobilized grafts. PBSCs mobilized by GROβΔ4 alone or with G-CSF contained significantly more Sca-1+-c-kit+-lineage− (SKL) cells and more primitive CD34−-SKL cells compared with cells mobilized by G-CSF and demonstrated superior competitive long-term repopulation activity, which continued to increase in secondary and tertiary recipients. GROβΔ4-mobilized SKL cells adhered better to VCAM-1+ endothelial cells compared with G-CSF–mobilized cells. GROβΔ4-mobilized PBSCs did not migrate well to the chemokine stromal derived factor (SDF)-1α in vitro that was associated with higher CD26 expression. However, GROβΔ4-mobilized SKL and c-Kit+ lineage− (KL) cells homed more efficiently to marrow in vivo, which was not affected by selective CXCR4 and CD26 antagonists. These data suggest that GROβΔ4-mobilized PBSCs are superior in reconstituting long-term hematopoiesis, which results from differential mobilization of early stem cells with enhanced homing and long-term repopulating capacity. In addition, homing and engraftment of GROβΔ4-mobilized cells is less dependent on the SDF-1α/CXCR4 axis.

Tie-2 receptor tyrosine kinase expressed in endothelial and hematopoietic cells is believed to play a role in both angiogenesis and hematopoiesis during development of the mouse embryo. This article addressed whether Tie-2 is expressed on fetal liver hematopoietic stem cells (HSCs) at day 14 of gestation. With the use of anti–Tie-2 monoclonal antibody, its expression was detected in approximately 7% of an HSC population of Kit-positive, Sca-1–positive, lineage-negative or -low, and AA4.1-positive (KSLA) cells. These Tie-2–positive KSLA (T+ KSLA) cells represent 0.01% to 0.02% of fetal liver cells. In vitro colony and in vivo competitive repopulation assays were performed for T+ KSLA cells and Tie-2–negative KSLA (T− KSLA) cells. In the presence of stem cell factor, interleukin-3, and erythropoietin, 80% of T+ KSLA cells formed colonies in vitro, compared with 40% of T− KSLA cells. Long-term multilineage repopulating cells were detected in T+ KSLA cells, but not in T− KSLA cells. An in vivo limiting dilution analysis revealed that at least 1 of 8 T+ KSLA cells were such repopulating cells. The successful secondary transplantation initiated with a limited number of T+ KSLA cells suggests that these cells have self-renewal potential. In addition, engraftment of T+ KSLA cells in conditioned newborn mice indicates that these HSCs can be adapted equally by the adult and newborn hematopoietic environments. The data suggest that T+ KSLA cells represent HSCs in the murine fetal liver.

Isolation And Characterization

Abstract Surface antigens on hematopoietic stem cells (HSCs) enable prospective isolation and characterization. Here, we compare the cell-surface phenotype of hematopoietic repopulating cells from murine yolk sac, aorta-gonad-mesonephros, placenta, fetal liver, and bone marrow with that of HSCs derived from the in vitro differentiation of murine embryonic stem cells (ESC-HSCs). Whereas c-Kit marks all HSC populations, CD41, CD45, CD34, and CD150 were developmentally regulated: the earliest embryonic HSCs express CD41 and CD34 and lack CD45 and CD150, whereas more mature HSCs lack CD41 and CD34 and express CD45 and CD150. ESC-HSCs express CD41 and CD150, lack CD34, and are heterogeneous for CD45. Finally, although CD48 was absent from all in vivo HSCs examined, ESC-HSCs were heterogeneous for the expression of this molecule. This unique phenotype signifies a developmentally immature population of cells with features of both primitive and mature HSC. The prospective fractionation of ESC-HSCs will facilitate studies of HSC maturation essential for normal functional engraftment in irradiated adults.

Growth factor erv1-like (Gfer) is an evolutionarily conserved sulfhydryl oxidase that is enriched in embryonic and adult stem cells and plays an essential prosurvival role in pluripotent embryonic stem cells. Here we show that knockdown (KD) of Gfer in hematopoietic stem cells (HSCs) compromises their in vivo engraftment potential and triggers a hyper-proliferative response that leads to their exhaustion. KD of Gfer in HSCs does not elicit a significant alteration of mitochondrial morphology or loss of cell viability. However, these cells possess significantly reduced levels of the cyclin-dependent kinase inhibitor p27kip1. In contrast, overexpression of Gfer in HSCs results in significantly elevated total and nuclear p27kip1. KD of Gfer results in enhanced binding of p27kip1 to its inhibitor, the COP9 signalosome subunit jun activation-domain binding protein 1 (Jab1), leading to its down-regulation. Conversely, overexpression of Gfer results in its enhanced binding to Jab1 and inhibition of the Jab1-p27kip1 interaction. Furthermore, normalization of p27kip1 in Gfer-KD HSCs rescues their in vitro proliferation deficits. Taken together, our data demonstrate the presence of a novel Gfer-Jab1-p27kip1 pathway in HSCs that functions to restrict abnormal proliferation.

Abstract Hematopoietic stem cells (HSCs) regenerated in vivo display sustained differences in their self-renewal and differentiation activities. Variations in Steel factor (SF) signaling are known to affect these functions in vitro, but the cellular and molecular mechanisms involved are not understood. To address these issues, we evaluated highly purified HSCs maintained in single-cell serum-free cultures containing 20 ng/mL IL-11 plus 1, 10, or 300 ng/mL SF. Under all conditions, more than 99% of the cells traversed a first cell cycle with similar kinetics. After 8 hours in the 10 or 300 ng/mL SF conditions, the frequency of HSCs remained unchanged. However, in the next 8 hours (ie, 6 hours before any cell divided), HSC integrity was sustained only in the 300 ng/mL SF cultures. The cells in these cultures also contained significantly higher levels of Bmi1, Lnk, and Ezh2 transcripts but not of several other regulators. Assessment of 21 first division progeny pairs further showed that only those generated in 300 ng/mL SF cultures contained HSCs and pairs of progeny with similar differentiation programs were not observed. Thus, SF signaling intensity can directly and coordinately alter the transcription factor profile and long-term repopulating ability of quiescent HSCs before their first division.

Abstract The Fas receptor and its ligand have been implicated in mediating the bone marrow (BM) suppression observed in graft-versus-host disease and a number of other BM-failure syndromes. However, previous studies have suggested that Fas is probably not expressed on human hematopoietic stem cells (HSCs), but up-regulated as a consequence of their commitment and differentiation, suggesting that progenitors or differentiated blood cells, rather than HSCs, are the targets of Fas-mediated suppression. The present studies confirm that candidate HSCs in human cord blood and BM lack constitutive expression of Fas, but demonstrate that Fas expression on CD34+ progenitor and stem cells is correlated to their cell cycle and activation status. With the use of recently developed in vitro conditions promoting HSC self-renewing divisions, Fas was up-regulated on virtually all HSCs capable of multilineage reconstituting nonobese diabetic/severe combined immunodeficiency (NOD-SCID) mice in vivo, as well as on long-term culture-initiating cells (LTC-ICs). Similarly, in vivo cycling of NOD-SCID repopulating cells upon transplantation, resulted in up-regulation of Fas expression. However, repopulating HSCs expressing high levels of Fas remained highly resistant to Fas-mediated suppression, and HSC function was compromised only upon coactivation with tumor necrosis factor. Thus, reconstituting human HSCs up-regulate Fas expression upon active cycling, demonstrating that HSCs could be targets for Fas-mediated BM suppression. (Blood. 2003;102: 118-126)
