Abstract
Bone marrow mesenchymal stem cells (BM-MSCs) are a potential tool for cell therapy and tissue engineering. In this study, we carried on a comparative study of the characteristics of MSCs from different age cynomolgus monkeys. A variety of factors, including donor age, must be considered before further applications, and various tests should be used to properly assess MSCs before the clinical application, especially when a prolonged culture and ex vivo expansion is necessary.

Abstract
The goal of this study was to compare the growth and differentiation potential of fetal and adult rhesus monkey (Macaca mulatta) mesenchymal stem cells (rhMSCs). rhMSCs were obtained from healthy early third-trimester fetal (n = 3) and adult (n = 3) rhesus monkey bone marrow. Fetal rhMSCs were plated at 10, 50, 100, or 1,000 cells/cm(2) in medium containing 10% or 20% infant monkey serum (IMS) or fetal bovine serum (FBS). Fetal rhMSCs grown at 1,000 cells/cm(2) in 20% FBS showed faster growth rates and differentiation toward adipogenic, chondrogenic, and osteogenic lineages when compared to other culture conditions and to adult cells (p < 0.05). Fetal rhMSC showed higher population doubling times (11.3 +/- 0.5) when compared to adult cells (7.3 +/- 0.8) during the first three passages. Adult rhMSC did not grow beyond the third passage under all culture conditions, including those supplemented with insulin-like growth factor (IGF)-I, IGF-II, platelet-derived growth factor (PDGF), and fibroblast growth factor-2 (FGF-2). After the third passage, adult rhMSC cultures were observed with large syncytia and with evidence of apoptosis. Cells obtained from these cultures tested positive for simian foamy virus (SFV) by PCR, RT-PCR, and immunofluorescent assay. Adult rhMSCs cultured with 10 microM tenofovir, an antiviral agent, showed normal growth and differentiation for over 20 population doublings. These findings suggest that: (1) fetal rhMSCs possess greater self-renewal and differentiation potential when compared to adult cells; and (2) SFV can inhibit proliferation of adult rhMSCs in culture, whereas the addition of tenofovir can successfully suppress SFV replication in vitro and result in resumed growth.

Abstract
Progress in developing effective gene transfer approaches to treat HIV-1 infection has been steady. Many different transgenes have been reported to inhibit HIV-1 in vitro. However, effective translation of such results to clinical practice, or even to animal models of AIDS, has been challenging. Among the reasons for this failure are uncertainty as to the most effective cell population(s) to target, the diffuseness of these target cells in the body, and ineffective or insufficiently durable gene delivery. Better understanding of the HIV-1 replicative cycle, host factors involved in HIV-1 infection, vector biology and application, transgene technology, animal models, and clinical study design have all contributed vastly to planning current and future strategies for application of gene therapeutic approaches to the treatment of AIDS. This review focuses on the newest developments in these areas and provides a strong basis for renewed optimism that gene therapy will have an important role to play in treating people infected with HIV-1.

Abstract
Progress in gerontological research has been promoted through the use of numerous animal models, which have helped identify possible mechanisms of aging and age-related chronic diseases and evaluate possible interventions with potential relevance to human aging and disease. Further development of nonhuman primate models, particularly rhesus monkeys, could accelerate this progress, because their closer genetic relationship to humans produces a highly similar aging phenotype. Because the relatively long lives of primates increase the administrative and economic demands on research involving them, new emphasis has emerged on increasing the efficient use of these valuable resources through cooperative, interdisciplinary research.

Abstract
Genetic modification of hematopoietic stem and progenitor cells has the potential to treat diseases affecting blood cells. Oncoretroviral vectors have been used for gene therapy; however, clinical success has been limited in part by low gene transfer efficiencies. We found that the presence of stromal-derived factor 1 (SDF-1alpha)/CXCL12 during retroviral transduction significantly enhanced, in a dose-dependent fashion, gene transfer into immature subsets of high proliferative human and murine hematopoietic progenitor cells. Murine mononuclear bone marrow cells and purified c-Kit(+)Lin(-) bone marrow cells were prestimulated and transduced with the bicistronic retroviral vector MIEG3 on Retronectin-coated surfaces in the presence and absence of SDF-1. SDF-1 enhanced gene transduction of murine bone marrow and c-Kit(+)Lin(-) cells by 35 and 29%, respectively. Moreover, SDF-1 enhanced transduction of progenitors in these populations by 121 and 107%, respectively. SDF-1 also enhanced transduction of human immature subsets of high proliferative progenitors present in either nonadherent mononuclear or CD34(+) umbilical cord blood cells. Transduction of hematopoietic progenitors was further increased by preloading Retronectin-coated plates with retrovirus using low-speed centrifugation followed by increasing cell-virus interactions through brief centrifugation during the transduction procedure. These results may be of clinical relevance.

Abstract
Soft tissue sarcomas are a challenge for medical oncology and gene therapy. Protective and sensitising approaches that target normal and malignant tissue, respectively, both have their role for opening the therapeutic window. Recent data show that an intensive maintenance chemotherapy significantly reduces metastatic spread and improves disease-free survival in selected patient groups. However, delays of treatment due to cytopenia are frequent. Cytostatic drug resistance gene transfer to haematopoietic progenitor cells using retroviral vectors may allow further improvement of therapy results. In recent years, retroviral vector design, transduction techniques and engraftment capability of transduced cells have been optimised. Safety considerations of retroviral gene transfer have attracted public attention and can be addressed by analysis of genomic vector integration sites. A data bank project, 'retroviral insertion estimate of chromosomal integration' (RISC), containing > 200 integration sequences, has been set up by the authors' group to recognise critical genomic regions and genes involved with possible transforming capacity. Monitoring these parameters will allow the selection of the most suitable vectors for clinical application. Sarcoma cells seem to be highly susceptible to a variety of vectors, such as recombinant adeno-associated virus-2 (rAAV-2) vectors, adenoviral vectors or oncolytic herpes simplex viruses. Results from the first clinical trials with adenoviral vectors encoding for cytokines are promising. The other systems await further development towards clinical applications. Perspectives for further research are discussed in this review.

Abstract
Before autoimmune diseases in humans can be treated with gene therapy, the safety and efficacy of the used vectors must be tested in valid experimental models. Monkeys, such as the rhesus macaque or the common marmoset, provide such models. This publication reviews the state of the art in monkey models for rheumatoid arthritis and multiple sclerosis and the (few) gene therapy experiments that have been performed in these models.

Abstract
For numerous malignancies a relationship between the intensity of antineoplastic chemotherapy and tumor response has been demonstrated. Myelotoxicity is the main cause of chemotherapy-associated morbidity and of treatment delays. The concept of myeloprotective cytostatic drug resistance gene transfer to normal hematopoietic stem cells (HSC) therefore sparks great enthusiasm. While initial studies using murine retroviral vectors on murine HSC showed that the concept works, a number of clinical studies in the last decade were not informative because of limitations in transduction efficiency and transgene expression.Furthermore, possible side effects such as unforeseen transgene activity and vector integration-based leukemogenesis have been reported. Among others, these developments raised some scepticism against the feasibility of myeloprotective gene transfer. Recently, considerable improvements have been achieved in vector design, HSC manipulation, selection protocols and risk assessment methods which are discussed in detail here. Based on these experimental studies successful clinical trials can now be anticipated.

Abstract
Efficient transduction of hematopoietic stem cells is a prerequisite for successful hematopoietic stem cell gene therapy. Oncoretroviral vectors are the most widely used vectors for hematopoietic gene therapy studies. However, these vectors require cell division, and thus efficient transduction of quiescent stem cells has been difficult to achieve. Lentiviral vectors can transduce non-dividing cells and therefore may be more efficient in transducing quiescent hematopoietic stem cells. We have used a competitive repopulation assay in the baboon to compare transduction of hematopoietic repopulating cells by lentiviral and oncoretroviral vectors. Baboon CD34-enriched marrow cells were transduced in the presence or absence of multiple hematopoietic growth factors using a short, 2-day, transduction protocol. Here, we show that efficient lentiviral transduction of hematopoietic repopulating cells was only achieved when cells were transduced in the presence of multiple growth factors. Using these conditions, up to 8.6% of hematopoietic repopulating cells were genetically modified by the lentiviral vector more than 1 year after transplant. Interestingly, the number of lentivirally marked cells increased over time in three of four animals. In conclusion, these results suggest that lentiviral vectors are able to tranduce multilineage hematopoietic stem cells, and thus, may provide an alternative vector system for clinical stem cell gene therapy applications.
