Abstract
Sheep are typically considered as industrial animals that provide wool and meals. However, they play a significant role in medical research in addition to their conventional use. Notably, sheep fetuses are resistant to surgical invasions and can endure numerous manipulations, such as needle puncture and cell transplantation, and surgical operations requiring exposure beyond the uterus. Based on these distinguishing characteristics, we established a chimeric sheep model capable of producing human/monkey pluripotent cell-derived blood cells via the fetal liver. Furthermore, sheep have become crucial as human fetal models, acting as platforms for developing and improving techniques for intrauterine surgery to address congenital disorders and clarifying the complex pharmacokinetic interactions between mothers and their fetuses. This study emphasizes the significant contributions of fetal sheep to advancing human disease understanding and treatment strategies, highlighting their unique characteristics that are not present in other animals.

Abstract
The application of mesenchymal stromal cells (MSCs) from different sources, including bone marrow (BM, bmMSCs), adipose tissue (atMSCs), and human term placenta (hPSCs) has been proposed for various clinical purposes. Accumulated evidence suggests that the activity of the different MSCs is indirect and associated with paracrine release of pro-regenerative and anti-inflammatory factors. A major limitation of bmMSCs-based treatment for autologous application is the limited yield of cells harvested from BM and the invasiveness of the procedure. Similar effects of autologous and allogeneic MSCs isolated from various other tissues were reported. The easily available fresh human placenta seems to represent a preferred source for harvesting abundant numbers of human hPSCs for allogenic use. Cells derived from the neonate tissues of the placenta (f-hPSC) can undergo extended expansion with a low risk of senescence. The low expression of HLA class I and II on f-hPSCs reduces the risk of rejection in allogeneic or xenogeneic applications in normal immunocompetent hosts. The main advantage of hPSCs-based therapies seems to lie in the secretion of a wide range of pro-regenerative and anti-inflammatory factors. This renders hPSCs as a very competent cell for therapy in humans or animal models. This review summarizes the therapeutic potential of allogeneic applications of f-hPSCs, with reference to their indirect pro-regenerative and anti-inflammatory effects and discusses clinical feasibility studies.

Abstract
We report that a sheep fetal liver provides a microenvironment for generating hematopoietic cells with long-term engrafting capacity and multilineage differentiation potential from human induced pluripotent stem cell (iPSC)-derived hemogenic endothelial cells (HEs). Despite the promise of iPSCs for making any cell types, generating hematopoietic stem and progenitor cells (HSPCs) is still a challenge. We hypothesized that the hematopoietic microenvironment, which exists in fetal liver but is lacking in vitro, turns iPSC-HEs into HSPCs. To test this, we transplanted CD45-negative iPSC-HEs into fetal sheep liver, in which HSPCs first grow. Within 2 months, the transplanted cells became CD45 positive and differentiated into multilineage blood cells in the fetal liver. Then, CD45-positive cells translocated to the bone marrow and were maintained there for 3 years with the capability of multilineage differentiation, indicating that hematopoietic cells with long-term engraftment potential were generated. Moreover, human hematopoietic cells were temporally enriched by xenogeneic donor-lymphocyte infusion into the sheep. This study could serve as a foundation to generate HSPCs from iPSCs.

Abstract
Blastocyst complementation combined with gene editing is an emerging approach in the
field of regenerative medicine that could potentially solve the worldwide problem of organ
shortages for transplantation. In theory, blastocyst complementation can generate fully
functional human organs or tissues, grown within genetically engineered livestock animals.
Targeted deletion of a specific gene(s) using gene editing to cause deficiencies in organ
development can open a niche for human stem cells to occupy, thus generating human
tissues. Within this review, we will focus on the pancreas, liver, heart, kidney, lung,
and skeletal muscle, as well as cells of the immune and nervous systems. Within each of
these organ systems, we identify and discuss (i) the common causes of organ failure; (ii)
the current state of regenerative therapies; and (iii) the candidate genes to knockout and
enable specific exogenous organ development via the use of blastocyst complementation. We
also highlight some of the current barriers limiting the success of blastocyst
complementation.

Abstract
Xenograft models of human hematopoiesis are essential to the study of the engraftment and
proliferative potential of human hematopoietic stem cells (HSCs) in vivo.
Immunodeficient mice and fetal sheep are often used as xenogeneic recipients because they
are immunologically naive. In this study, we transplanted human HSCs into fetal sheep and
assessed the long-term engraftment of transplanted human HSCs after birth. Fourteen sheep
were used in this study. In 4 fetal sheep, HSCs were transduced with homeo-box B4
(HOXB4) gene before transplantation, which promoted the expansion of
HSCs. Another 4 fetal sheep were subjected to non-myeloablative conditioning with
busulfan. Seven of these 8 sheep showed successful engraftment of human HSCs (1–3% of
colony-forming units) as assessed after the birth of fetal sheep (5 months
post-transplantation), although HOXB4-transduced HSCs showed sustained
engraftment for up to 40 months. Intact HSCs were transplanted into six non-conditioned
fetal sheep, and human colony-forming units were not detected in the sheep after birth.
These results suggest that, as compared with mouse models, where the short lifespan of
mice limits long-term follow-up of HSC engraftment, the fetal sheep model provides a
unique perspective for evaluating long-term engraftment and proliferation of human
HSCs.

Abstract
Pluripotent stem cells represent an attractive cell source for regenerative medicine. However, the risk of teratoma formation after transplantation restricts their clinical application. Therefore, to adequately evaluate the potential risk of tumorigenicity after cell transplantation into human tissues, effective animal transplantation assays need to be developed. We performed a multiparameter (cell number, transplantation site, cell type, host) comparative analysis of the efficiency of tumor development after transplantation of mouse and human embryonic stem (ES) cells and their malignant counterparts, teratocarcinoma (EC) cells, into animal recipients and revealed several key correlations. We found that the efficiency of tumor growth was higher after intra-peritoneal than after subcutaneous transplantations of all cell lines studied. The minimal cell numbers sufficient for tumor growth in immunodeficient nude mice were 100-fold lower for intraperitoneal than for subcutaneous transplantations of mouse and human ES cells (103 vs. 105 and 104 vs. 106, respectively). Moreover, mouse ES and EC cells formed tumors in immunodeficient and immunocompetent mice more effectively than human ES and EC cells. After intraperitoneal transplantation of 103, 104, and 105 mouse ES cells, teratomas developed in 83%, 100%, and 100% of nude mice, whereas after human ES cell transplantation, teratomas developed in 0%, 17%, and 60%, respectively. In addition, malignant mouse and human EC cells initiated tumor growth after intraperitoneal transplantation significantly faster and more effectively than ES cells. Mouse and human ES cells formed different types of teratomas containing derivatives of three germ layers but different numbers of undifferentiated cells. ES cell-like sublines with differentiation potential similar to the parental cell line were recloned only from mouse, but not from human, ES cell teratomas. These findings provide new information about the possibility and efficiency of tumor growth after transplantation of pluripotent stem cells. This information allows one to predict and possibly prevent the possible risks of tumorigenicity that could arise from stem cell therapeutics.

Abstract
In vitro generation of hematopoietic stem cells (HSCs) from induced pluripotent stem cells (iPSCs) has the potential to provide novel therapeutic approaches for replacing bone marrow (BM) transplantation without rejection or graft versus host disease. Hitherto, however, it has proved difficult to generate truly functional HSCs transplantable to adult host mice. Here, we demonstrate a unique in vivo differentiation system yielding engraftable HSCs from mouse and human iPSCs in teratoma-bearing animals in combination with a maneuver to facilitate hematopoiesis. In mice, we found that iPSC-derived HSCs migrate from teratomas into the BM and their intravenous injection into irradiated recipients resulted in multilineage and long-term reconstitution of the hematolymphopoietic system in serial transfers. Using this in vivo generation system, we could demonstrate that X-linked severe combined immunodeficiency (X-SCID) mice can be treated by HSCs derived from gene-corrected clonal iPSCs. It should also be noted that neither leukemia nor tumors were observed in recipients after transplantation of iPSC-derived HSCs. Taken our findings together, our system presented in this report should provide a useful tool not only for the study of HSCs, but also for practical application of iPSCs in the treatment of hematologic and immunologic diseases.

Maternal administration of busulfan before in utero transplantation of human hematopoietic stem cells enhances engraftments in sheep. Exp Hematol 2012; 40:436-44.

Abstract
In utero transplantation (IUT) of human hematopoietic stem cells has been conducted in sheep, which are used as large animal models of human hematopoietic reconstitution and models for clinical IUT; however, the levels of engraftment have generally been low. Busulfan (BU), a myeloablative agent, is often administered to patients before hematopoietic stem cells transplantation to improve the engraftment. In this study, hematopoietic activity was evaluated in adult sheep after administering BU at different doses. Next, pregnant ewes were administered BU, and dams as well as their fetuses were evaluated, as BU readily crosses the sheep placenta. Then, the BU dose with the desired outcomes was selected and administered to pregnant ewes at 2 or 6 days before performing IUT using human cord blood CD34(+) cells. The engraftment was evaluated in recipients that underwent IUT in the presence or absence of BU. As a result, hematopoietic activity was safely and transiently suppressed in adult sheep treated with 5 to 7.5 mg/kg BU. BU crossed the sheep placenta, and fetal sheep were indeed conditioned by administering 3 mg/kg BU to pregnant ewes. Engraftment of human CD34(+) cells in fetal recipients was enhanced when IUT was carried out 6 days post-BU. Up to 3.3% engraftment levels (in terms of bone marrow colony-forming units) were achieved with the IUT of 0.72 to 2.4 million CD34(+) cells when BU was used. BU can be administered to pregnant ewes to effectively condition the fetal recipient for IUT with enhanced engraftment of donor cells.

Abstract
OBJECTIVE The homeobox B4 (HoxB4) gene promotes expansion of hematopoietic stem cells (HSCs). However, frequent development of leukemia in large animals due to retrovirally transduced HoxB4 gene has been reported. To prevent tumorigenesis, we developed a nonintegrating and nonreplicating Sendai virus vector that did not contain the phosphoprotein gene (SeV/ΔP), which enabled clearance of the vector and transgene shortly after transduction. We tested the SeV/ΔP vector expressing the HoxB4 gene (SeV/ΔP/HoxB4) for the ex vivo expansion of human cord blood CD34(+) cells (HSCs) using a sheep in utero transplantation assay. MATERIALS AND METHODS Human HSCs were ex vivo-expanded by transduction with SeV/ΔP/HoxB4 vector and transplanted into the abdominal cavity of fetal sheep. The engraftment of human HSCs in the lambs was quantitatively evaluated by hematopoietic colony-forming unit assays. RESULTS After transplantation, the HoxB4-transduced HSCs contributed to longer-period (up to 20 months) repopulation in sheep, and human hematopoietic progenitors were detected more frequently in the bone marrow of the HoxB4 group as compared with the control untreated group (p < 0.05). The expansion of human HSCs with the SeV/ΔP/HoxB4 vector was comparable with previously reported retroviral vectors expressing HoxB4. The SeV/ΔP/HoxB4 vector and the transgene were cleared from the recipient sheep and leukemia was not detected at 20 months post-transplantation. CONCLUSIONS The SeV/ΔP vector would be suitable for transient expression of HoxB4 in human CD34(+) cells. In addition, the SeV/ΔP vector is free of concern about transgene-related and insertional leukemogenesis and should be safer than retroviral vectors.

Abstract
In the present study, we investigated the suitability of two methods for the transplantation of cells into ovine fetuses. The first method was an ultrasound-guided cell injection via the uterine wall. The second involved hysterotomic cell injection with an incision in the uterine wall exposing the amnion. Monkey embryonic stem (ES) cell-derived hematopoietic cells were used as donor cells. After transplantation, the abortion rate associated with the hysterotomic injection method was significantly higher than that of the ultrasound-guided injection method (8/13 versus 4/24; P < 0.01). The fetuses were delivered to examine the engraftment of transplanted monkey hematopoietic cells. Monkey cells were detected in one of the five animals (20%) in the hysterotomic injection group, and 14 of 20 animals (70%, P < 0.05) in the ultrasound-guided injection group. Therefore, the ultrasound-guided method was effectively shown to be minimally invasive for in utero transplantation and can produce a higher rate of engraftment for transplanted cells.

Abstract
Embryonic stem (ES) cells have the ability to generate teratomas when transplanted into immunodeficient mice, but conditions affecting the generation remain to be elucidated. Nonhuman primate cynomolgus ES cells were transplanted into immunodeficient mice under different conditions; the number of transplanted cells, physical state (clumps or single dissociated cells), transplant site, differentiation state, and immunological state of recipient mice were all varied. The tumorigenicity was then evaluated. When cynomolgus ES cells were transplanted as clumps into the lower limb muscle in either nonobese diabetic/severe combined immunodeficiency (NOD/SCID) or NOD/SCID/?cnull (NOG) mice, teratomas developed in all the animals transplanted with 1 × 105 or more cells, but were not observed in any mouse transplanted with 1 × 103 cells. However, when the cells were transplanted as dissociated cells, the number of cells necessary for teratomas to form in all mice increased to 5 × 105. When the clump cells were injected subcutaneously (instead of intramuscularly), the number also increased to 5 × 105. When cynomolgus ES cell-derived progenitor cells (1 × 106), which included residual pluripotent cells, were transplanted into the lower limb muscle of NOG or NOD/SCID mice, the incidence of teratomas differed between the strains; teratomas developed in five of five NOG mice but in only two of five NOD/SCID mice. The incidence of teratomas varied substantially depending on the transplanted cells and recipient mice. Thus, considerable care must be taken as to tumorigenicity.

Abstract
PURPOSE OF REVIEW Hematopoietic development from embryonic stem cells has been one of the most productive areas of stem cell biology. Recent studies have progressed from work with mouse to human embryonic stem cells. Strategies to produce defined blood cell populations can be used to better understand normal and abnormal hematopoiesis, as well as potentially improve the generation of hematopoietic cells with therapeutic potential. RECENT FINDINGS Molecular profiling, phenotypic and functional analyses have all been utilized to demonstrate that hematopoietic cells derived from embryonic stem cells most closely represent a stage of hematopoiesis that occurs at embryonic/fetal developmental stages. Generation of hematopoietic stem/progenitor cells comparable to hematopoietic stem cells found in the adult sources, such as bone marrow and cord blood, still remains challenging. However, genetic manipulation of intrinsic factors during hematopoietic differentiation has proven a suitable approach to induce adult definitive hematopoiesis from embryonic stem cells. SUMMARY Concrete evidence has shown that embryonic stem cells provide a powerful approach to study the early stage of hematopoiesis. Multiple hematopoietic lineages can be generated from embryonic stem cells, although most of the evidence suggests that hematopoietic development from embryonic stem cells mimics an embryonic/fetal stage of hematopoiesis.

Abstract
Progress toward clinical application of ESC-derived hematopoietic cellular transplantation will require rigorous evaluation in a large animal allogeneic model. However, in contrast to human ESCs (hESCs), efforts to induce conclusive hematopoietic differentiation from rhesus macaque ESCs (rESCs) have been unsuccessful. Characterizing these poorly understood functional differences will facilitate progress in this area and likely clarify the critical steps involved in the hematopoietic differentiation of ESCs. To accomplish this goal, we compared the hematopoietic differentiation of hESCs with that of rESCs in both EB culture and stroma coculture. Initially, undifferentiated rESCs and hESCs were adapted to growth on Matrigel without a change in their phenotype or karyotype. Subsequent differentiation of rESCs in OP9 stroma led to the development of CD34(+)CD45(-) cells that gave rise to endothelial cell networks in methylcellulose culture. In the same conditions, hESCs exhibited convincing hematopoietic differentiation. In cytokine-supplemented EB culture, rESCs demonstrated improved hematopoietic differentiation with higher levels of CD34(+) and detectable levels of CD45(+) cells. However, these levels remained dramatically lower than those for hESCs in identical culture conditions. Subsequent plating of cytokine-supplemented rhesus EBs in methylcellulose culture led to the formation of mixed colonies of erythroid, myeloid, and endothelial cells, confirming the existence of bipotential hematoendothelial progenitors in the cytokine-supplemented EB cultures. Evaluation of four different rESC lines confirmed the validity of these disparities. Although rESCs have the potential for hematopoietic differentiation, they exhibit a pause at the hemangioblast stage of hematopoietic development in culture conditions developed for hESCs.

Abstract
OBJECTIVE Human embryonic stem cells (hESCs) have been shown to generate CD34(+) primitive hematopoietic cells after several days of coculturing with the OP9 murine stromal cell line. CD73(+) multipotent mesenchymal cells have also been isolated from hESC/OP9 cocultures after several weeks. We hypothesized that generation of CD34(+) hematopoietic cells and CD73(+) mesenchymal stem cells (MSCs) may follow similar kinetics, so we investigated the generation of CD73(+) cells in the first 2 weeks of hESC/OP9 cocultures, at a time when CD34(+) cells are generated. MATERIALS AND METHODS We cocultured hESCs with OP9 cells and examined the time course of appearance of human CD34(+) and CD73(+) cells using flow cytometry. We tested the hematopoietic progenitor potentials of CD34(+) cells generated using hematopoietic colony-forming assays, and the multipotent mesenchymal properties of CD73(+) cells generated using in vitro differentiation assays. RESULTS We observed that in the first 2 weeks of the hESC/OP9 coculture system CD34(+) hematopoietic and CD73(+) MSC generation follows a similar pattern. We sorted the CD34(+) cells and showed that they can generate hematopoietic progenitor colonies. Starting with cocultured cells on day 8, and through an enrichment procedure, we also could generate a pure population of MSCs. These hESC-derived MSCs had typical morphological and cell surface marker characteristics of adult bone marrow-derived MSCs, and could be differentiated toward osteogenic, adipogenic, and chondrogenic cells in vitro, a hallmark property of MSCs. CONCLUSIONS OP9 cells when cocultured with hESCs support simultaneous generation of CD34(+) primitive hematopoietic cells and CD73(+) MSCs from hESCs.

Abstract
Cynomolgus monkey embryonic stem cell (cyESC)-derived in vivo hematopoiesis was examined in an allogeneic transplantation model. cyESCs were induced to differentiate into the putative hematopoietic precursors in vitro, and the cells were transplanted into the fetal cynomolgus liver at approximately the end of the first trimester (n = 3). Although cyESC-derived hematopoietic colony-forming cells were detected in the newborns (4.1%-4.7%), a teratoma developed in all newborns. The risk of tumor formation was high in this allogeneic transplantation model, given that tumors were hardly observed in immunodeficient mice or fetal sheep that had been xeno-transplanted with the same cyESC derivatives. It turned out that the cyESC-derived donor cells included a residual undifferentiated fraction positive for stage-specific embryonic antigen (SSEA)-4 (38.2% +/- 10.3%) despite the rigorous differentiation culture. When an SSEA-4-negative fraction was transplanted (n = 6), the teratoma was no longer observed, whereas the cyESC-derived hematopoietic engraftment was unperturbed (2.3%-5.0%). SSEA-4 is therefore a clinically relevant pluripotency marker of primate embryonic stem cells (ESCs). Purging pluripotent cells with this surface marker would be a promising method of producing clinical progenitor cell preparations using human ESCs.

Abstract
Human embryonic stem cells (hESCs) provide an important means to characterize early stages of hematopoietic development. However, the in vivo potential of hESC-derived hematopoietic cells has not been well defined. We demonstrate that hESC-derived cells are capable of long-term hematopoietic engraftment when transplanted into nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice. Human CD45(+) and CD34(+) cells are identified in the mouse bone marrow (BM) more than 3 months after injection of hESCs that were allowed to differentiate on S17 stromal cells for 7-24 days. Secondary engraftment studies further confirm long-term repopulating cells derived from hESCs. We also evaluated two mechanisms that may inhibit engraftment: host immunity and requirement for homing to BM. Treatment with anti-ASGM1 antiserum that primarily acts by depletion of natural killer cells in transplanted mice leads to improved engraftment, likely due to low levels of HLA class I expressed on hESCs and CD34(+) cells derived from hESCs. Intra-BM injection also provided stable engraftment, with hematopoietic cells identified in both the injected and contra-lateral femur. Importantly, no teratomas are evident in animals injected with differentiated hESCs. These results demonstrate that SCID-repopulating cells, a close surrogate for hematopoietic stem cells, can be derived from hESCs. Moreover, both adaptive and innate immune effector cells may be barriers to engraftment of these cells.

Abstract
Embryonic stem (ES) cells, derived from early stage embryos, are pluripotent precursors of all of the tissues and organs of the body. ES cells from the mouse have been shown to undergo differentiation in vitro to form a variety of different cell types, including the differentiated progeny of hematopoietic precursors. These hematopoietic cells, however, exhibit numerous differences from those of human cells, and it has become increasingly clear that mouse ES cell differentiation has significant limitations as a model of human developmental biology. The more recent isolation and characterization of nonhuman primate ES cell lines have made available an experimental model with characteristics considerably more close to human biology. We have developed experimental conditions that promote efficient differentiation of these cells to produce progeny cells with considerable similarity to hematopoietic precursors harvested from bone marrow of adult animals.

Abstract
Murine embryonic stem cells (mESC) readily form embryoid bodies (EBs) that exhibit hematopoietic differentiation. Methods based on EB formation or ESC coculture with murine bone marrow stromal cell lines have revealed pathways of both primitive and definitive hematopoietic differentiation progressing from primitive mesoderm via hemangioblasts to endothelium and hematopoietic stem and progenitor cells. The addition of specific hematopoietic growth factors and morphogens to these cultures enhances the generation of neutrophils, macrophages, megakaryocyte/platelets, and hemoglobinized mature red cells. In addition, selective culture systems have been developed to support differentiation into mature T lymphocytes, natural killer cells, B cells, and dendritic cells. In most cases, culture systems have been developed that support equivalent differentiation of various human ESC (hESC). The major obstacle to translation of ESC hematopoietic cultures to clinical relevance has been the general inability to produce hematopoietic stem cells (HSC) that can engraft adult, irradiated recipients. In this context, the pattern of ES hematopoietic development mirrors the yolk sac phase of hematopoiesis that precedes the appearance of engraftable HSC in the aorta-gonad-mesonephros region. Genetic manipulation of mESC hematopoietic progeny by upregulation of HOXB4 or STAT5 has led to greatly enhanced long- or short-term multilineage hematopoietic engraftment, suggesting that genetic or epigenetic manipulation of these pathways may lead to functional HSC generation from hESC.

Abstract
Human embryonic stem cells (hESCs) provide a unique resource to analyze early stages of human hematopoiesis. However, little is known about the ability to use hESCs to evaluate lymphocyte development. In the present study, we use a two-step culture method to demonstrate efficient generation of functional NK cells from hESCs. The CD56(+)CD45(+) hESC-derived lymphocytes express inhibitory and activating receptors typical of mature NK cells, including killer cell Ig-like receptors, natural cytotoxicity receptors, and CD16. Limiting dilution analysis suggests that these cells can be produced from hESC-derived hemopoietic progenitors at a clonal frequency similar to CD34(+) cells isolated from cord blood. The hESC-derived NK cells acquire the ability to lyse human tumor cells by both direct cell-mediated cytotoxicity and Ab-dependent cellular cytotoxicity. Additionally, activated hESC-derived NK cells up-regulate cytokine production. hESC-derived lymphoid progenitors provide a novel means to characterize specific cellular and molecular mechanisms that lead to development of specific human lymphocyte populations. These cells may also provide a source for innovative cellular immune therapies.

Abstract
The human/sheep xenograft model has proven valuable in assessing the in vivo hematopoietic activity of stem cells from a variety of fetal and postnatal human sources. CD34+/lineage- or CD34+/CD38- cells isolated from human embryonic stem cells (hESCs) differentiated on S17 feeder layer were transplanted by intraperitoneal injections into fetal sheep. Chimerism in primary transplants was established with polymerase chain reaction (PCR) and flow cytometry of bone marrow and peripheral blood samples. Whole bone marrow cells harvested from a primary recipient were transplanted into a secondary recipient. Chimerism was established as described before. This animal was stimulated with human GM-CSF, and an increase in human hematopoietic activity was noted by flow cytometry. Bone marrow aspirations cultured in methylcellulose generated colonies identified by PCR to be of human origin. We therefore conclude that hESCs are capable of generating hematopoietic cells that engraft primary recipients. These cells also fulfill the criteria for long-term engrafting hematopoietic stem cells as demonstrated by engraftment and differentiation in the secondary recipient.

Abstract
Stem cell-based regenerative medicine therapies have been touted recently as a novel therapeutic approach to treat and cure a wide range of diseases. Both adult and embryonic stem (ES) cells can serve as important sources of precursor cells to derive more mature cells potentially utilized for clinical applications. Nonhuman primates have proven useful as a preclinical model, as demonstrated in studies of hematopoietic cell transplantation, gene therapy, and other areas. The derivation of nonhuman primate ES cells now provides an optimal resource to characterize and test ES cell-based therapies prior to trials with human ES cells. This review describes work to define strategies and mechanisms to derive blood and endothelial cells from nonhuman primate ES cells isolated from various species. Preclinical testing that solely relies on studies of putative therapeutic cells derived from mouse ES cells transplanted into other mice, or analyses of human ES cell-derived cells transplanted into immunodeficient or immunosuppressed rodents may not be predictive of efficacy in subsequent human trials. However, future testing using nonhuman primate ES cell-derived therapeutic cells done as an allogeneic transplant may best predict success for subsequent studies using human ES cells. Therefore, additional research on nonhuman primate ES cells, in addition to work on mouse and human ES cells, is greatly needed to facilitate clinical translation of new stem cell treatments.
