Abstract
Haematopoietic stem and progenitor cells (HSPCs) are used for transplantation to reconstruct the haematopoietic pathways in humans receiving severe chemotherapy. However, the characteristics of canine HSPCs, such as specific surface antigens and gene expression profiles, are still unclear. This study aimed to characterise the haematopoietic ability and gene expression profiles of canine bone marrow HSPCs in healthy dogs. In this study, the CD34 positive (CD34+) cells were defined as classical HSPCs, CD34+/CD45 diminished (CD45dim) cells as more enriched HSPCs, and whole viable cells as controls. Haematopoietic abilities and gene expression profiles were evaluated using a colony-forming unit assay and RNA-sequencing analysis. Canine CD34+/CD45dim cells exhibited a significantly higher haematopoietic colony formation ability and expressed more similarity in the gene expression profiles to human and mouse HSPCs than those of the other cell fractions. Furthermore, the canine CD34+/CD45dim cells expressed candidate cell surface antigens necessary to define the canine haematopoietic hierarchy roadmap. These results indicate that the canine CD34+/CD45dim cells express the HSPC characteristics more than the other cell fractions, thereby suggesting that these cells have the potential to be used for studying haematopoietic stem cells in dogs.

Abstract
Th17 cells are T helper cells which play an important role during inflammation and autoimmune disease. To investigate the role of these cells in diseases in dogs in a clinical setting, methods for fast identification had to be established. Th17 cells are a rare cell population, for their measurement stimulation is recommended. To examine more samples simultaneously and to receive a relatively high purity of cell population of CD3 + CD4+ cells, different methods on various levels of preselection of cells as well as the possibility of storing blood overnight for measuring Th17 cells by flow cytometry were investigated. Firstly, to receive a high number of mononuclear cells, two different density gradients were compared and analysed. Furthermore, the enrichment of CD3 + CD4+ cells via depletion of CD8alpha+, CD11b + and CD21+ cells by cell sorting (autoMACS Pro Separator) was tested. It was also investigated whether stimulation processes led to better interpretation of results and whether there was a significant difference in measurement of directly processed blood samples and samples that had been stored overnight. In conclusion, the use of the density gradient (Lymph24+ Spin Medium) resulted in a purer cell population through a significant decrease in polymorphonuclear cells (*p = 0.01). After cell sorting, a significant difference in cell population purity was detected. Within the target fraction (containing mainly CD3 + CD4+ cells), CD8alpha+, CD21+, CD11b + cell percentages were significantly lower (***p < 0.001, *p < 0.02, ***p < .0001, respectively), and CD3 + CD4+ cell percentage was significantly higher (***p < .0001). There was a significant difference in Th17 cell percentage between unstimulated and stimulated cell populations (***p < .0001), but no significant difference in the percentage of unstimulated Th17 cells (p = 0.29) or stimulated Th17 cells (p = 0.71) in stored blood in comparison to directly processed EDTA blood samples. Finally, a modified protocol that offers an efficient way to investigate samples that were stored overnight by means of flow cytometry was evolved to research the role of Th17 cells in dogs with different diseases or in healthy populations.

Abstract
Pre-clinical haematopoietic cell transplantation (HCT) studies in canines have proven to be invaluable for establishing HCT as a highly successful clinical option for the treatment of malignant and non-malignant haematological diseases in humans. Additionally, studies in canines have shown that immune tolerance, established following HCT, enabled transplantation of solid organs without the need of lifelong immunosuppression. This progress has been possible due to multiple biological similarities between dog and mankind. In this review, the hurdles that were overcome and the methods that were developed in the dog HCT model which made HCT clinically possible are examined. The results of these studies justify the question whether HCT can be used in the veterinary clinical practice for more wide-spread successful treatment of canine haematologic and non-haematologic disorders and whether it is prudent to do so.

Abstract
Using two-color flow cytometry, we characterized CD34(+) cells in the newborn canine thymus. CD34(+) thymic cells comprised approximately 5% of cells recovered by thymus tissue teasing and both large and small thymocytes have been present in this population, the former being 7-12 times more frequent. All CD34(+) cells expressed the pan-leukocyte antigen CD45. The expression of CD44 profile on the large and small CD34(+) thymocytes differed: almost all large CD34(+) cells were CD44(+), while only 75% of small CD34(+) thymocytes co-expressed the CD44 antigen. We have previously described that CD172α is present on the surface of CD34(+) bone marrow cells in dogs. In the thymus, CD172α was expressed on 5-10% and less than 5% of large and small CD34(+) cells, respectively. Some CD34(+) thymocytes also co-expressed T-lineage-specific markers like CD3, CD4, CD8, TCR1 and TCR2. Their expression increased during the large-to-small thymocyte transition. Based on our findings we suggest that thymocyte progenitors enter their primary differentiation center as large CD34(+), CD44(+), CD45(+) and CD172α(+) cells. T-cell specific markers appear on their surface at early stages of differentiation. As the size of progenitors decreases with terminal primary differentiation, the CD34, CD44, and CD172α surface markers are down-regulated.

Abstract
The umbilical cord blood (UCB) is an important source of pluripotent stem cells, which motivated researches on ontogeny and transplantation. The morphological characterization of umbilical cord cells is the first step to establish subsequent experiments on these areas. Although some information on humans can be found, no data on UCB is available for bovines. Therefore, this work is the first attempt to conduct an ultrastructural characterization of bovine umbilical cord blood. Blood was collected from the umbilical cord of twenty fetuses by punction of the umbilical vein. Samples were processed for whole leucocytes observation by centrifugation and the buffy coat was collected. Cells were washed and pelleted and prepared according to the standard protocol of the transmission electron microscopy. The presence of cells with morphologic characteristics compatible with the precursors from the erythrocytic, neutrophilic, eosinophilic, basophilic, and lymphocytic lineages was observed. Atypical cells with peculiar morphological features, strongly similar to apoptotic cells, were seen. Bovine neutrophils with three types of cytoplasmic granules were also found in the blood. The ultrastructural characteristics of observed bovine UCB cells where similar to those found in other species, suggesting that bovines could possibly constitute an experimental model for approaches on UCB cells research.

Abstract
Stem cells are critical in maintaining adult homeostasis and have been proposed to be the origin of many solid tumors, including pancreatic cancer. Here we demonstrate the expression patterns of the putative intestinal stem cell marker DCAMKL-1 in the pancreas of uninjured C57BL/6 mice compared with other pancreatic stem/progenitor cell markers. We then determined the viability of isolated pancreatic stem/progenitor cells in isotransplantation assays following DCAMKL-1 antibody-based cell sorting. Sorted cells were grown in suspension culture and injected into the flanks of athymic nude mice. Here we report that DCAMKL-1 is expressed in the main pancreatic duct epithelia and islets, but not within acinar cells. Coexpression was observed with somatostatin, NGN3, and nestin, but not glucagon or insulin. Isolated DCAMKL-1+ cells formed spheroids in suspension culture and induced nodule formation in isotransplantation assays. Analysis of nodules demonstrated markers of early pancreatic development (PDX-1), glandular epithelium (cytokeratin-14 and Ep-CAM), and isletlike structures (somatostatin and secretin). These data taken together suggest that DCAMKL-1 is a novel putative stem/progenitor marker, can be used to isolate normal pancreatic stem/progenitors, and potentially regenerates pancreatic tissues. This may represent a novel tool for regenerative medicine and a target for anti-stem cell-based therapeutics in pancreatic cancer.

Abstract
Bladder cancer stem (initiating) cell has not been isolated now, and no one verified its persistence experimentally. The aim of this study was to conclude the persistence of bladder cancer stem (initiating) cell in human primary bladder cancer and investigate the possibility of EMA(-) CD44v6(+) as markers of bladder cancer stem (initiating) cell. Genes differentially expressed between normal urothelium and low malignant bladder cancer were identified by DNA array assay. Overpressed stem cell related genes, Bmi-1 and EZH2, were verified by immunohistochemistry. Side population cells in bladder cancer were found under fluorescence microscope. The value of 28 potential surface markers of bladder cancer stem (initiating) cell for isolating them were judged by immunohistochemistry. Both EMA(-) and CD44v6(+) cells located in basal layer (potential location of stem cells). After gathering the CD44v6(+) cells and EMA(-) cells by magnetic cell sorting, their ability for colony-forming, self-renewal and extensive proliferation were assayed by cells culture. Both EMA(-) cells and CD44v6(+) cells posses the ability for colony-forming, self-renewal and proliferation. We conclude the persistence of bladder cancer stem (initiating) cell. Bladder cancer stem (initiating) cell might be among EMA(-) CD44v6(+) subset. Our strategies for isolating bladder cancer stem (initiating) cell might be useful for isolating other undetermined epithelial cancer stem cell, especially those in well-differentiated cancers.

Abstract
OBJECTIVE Hematopoietic chimerism, a state where donor and recipient bone marrow cells coexist, is associated with donor-specific tolerance. Nonmyeloablative bone marrow transplantation (BMT) has been shown to induce stable mixed hematopoietic chimerism in dog leukocyte antigen (DLA)-matched dogs. The potential for inducing renal and skin allograft tolerance with nonmyeloablative BMT was investigated in DLA-identical and DLA-haploidentical dogs in this study. MATERIALS AND METHODS Renal allografts were performed in 8 DLA-identical and 4 DLA-haploidentical dogs with nonmyeloablative conditioning (200 cGy TBI) and transient immunosuppression with cyclosporine (CSP) and mycophenolate mofetil (MMF) with (n = 8) and without (n = 4) simultaneous BMT. Skin allografts were performed in 2 DLA-identical and 4 DLA-haploidentical dogs after stopping CSP and MMF. Two DLA-identical control dogs received renal allografts without TBI, BMT, or immunosuppression with CSP and MMF. Molecular chimerism was determined with a PCR-based DNA microsatellite assay. Serum creatinine (Cr) concentration, urine specific gravity, and sequential renal biopsies were monitored to assess renal allograft function. RESULTS Donor-type blood cells were first detected 4 weeks posttransplantation in both the myeloid and lymphoid lineages. Donor chimerism was present for at least 76 weeks in the DLA-identical dogs. Mixed chimerism was not observed in the DLA-haploidentical dogs or DLA-identical dogs that did not undergo BMT. The renal allografts were acutely rejected within 14 days in the 2 DLA-identical control dogs. There was long-term (> 5 yrs) renal allograft survival as evidenced by a normal (< 2.0 mg/dL) serum Cr concentration in both the DLA-identical and DLA-haploidentical dogs that underwent 200 cGy TBI and transient immunosuppression with CSP and MMF either with or without simultaneous BMT. Renal allograft inflammation was severe in the control dogs, mild to moderate in the DLA-haploidentical dogs, and minimal in the DLA-identical dogs. Donor-specific skin grafts were accepted in the DLA-identical dogs but rejected in the DLA-haploidentical dogs. Nonmyeloablative conditioning (200 cGy TBI) and transient immunosuppression with CSP and MMF induce renal and skin allograft tolerance in DLA-identical and permit long-term renal allograft survival in DLA-haploidentical dogs. These findings suggest it may possible to obtain long-term allograft survival in DLA-identical and -haploidentical dogs without the need for chronic immunosuppressive therapy.

Abstract
A retrovirus vector containing an enhanced green fluorescent protein complimentary DNA (EGFP cDNA) was used to mark and dynamically follow vector-expressing cells in the peripheral blood of bone marrow transplanted X-linked severe combined immunodeficient dogs. CD34(+) cells isolated from young normal dogs were transduced, using a 2 day protocol, with an amphotropic retroviral vector that expressed enhanced green fluorescent protein (EGFP) and the canine common gamma chain (gammac) cDNAs. Following transplantation of the transduced cells, normal donor peripheral blood lymphocytes (PBL) appeared by 1 month post-bone marrow transplant (BMT) and rescued three of five treated dogs from their lethal immunodeficiency. PCR and flow cytometric analysis of post-BMT PBL documented the peripheral EGFP expressing cells as CD3(+) T cells, which varied from 0% to 28%. Sorting of EGFP(+) and EGFP(-) peripheral blood T cells from two dogs, followed by vector PCR analysis, showed no evidence of vector shutdown. EGFP expression in B cells or monocytes was not detected. These marking experiments demonstrate that the transduction protocol did not abolish the lymphoid engraftment capability of ex vivo transduced canine CD34(+) cells and supports the potential utility of the MSCV retroviral vector for gene transfer to XSCID affected canine hematopoietic progenitor cells (HPC).

Abstract
For ultimate diagnoses of canine leukemia or malignant lymphoma, we sought to isolate hematopoietic progenitor cells (HPCs) from canine bone marrow (BM) using physiological phenotypes. Canine BM cells were separated by equilibrium discontinued density centrifugation, and HPCs, detected by in vitro colony formation, were significantly enriched in the relatively low density (LD) fraction. In flow cytometry, many CD34 or MHC class II expressing cells were detected in the LD fraction, but these were not significantly enriched. When the LD cells were separated, using a cell-sorting method, into cells with high affinity of wheat germ agglutinin (WGAhigh) and cells with WGAlow, almost all multipotent HPCs (MHPCs) and HPCs committed to myeloid lineage were found in the WGAhigh population. When the WGAhigh population was further stained for rhodamin 123, almost all MHPCs were included in the dull population (Rhlow), but not in the bright one (Rhhigh). Morphologically, most Rhlow cells were round, blastic cells containing a large nucleus with nucleoli and narrow cytoplasm. Based on these results, we suggest that all of the MHPCs in canine BM show the Rhlow WGAhigh LD phenotype, and may contain hematopoietic stem cells, which are the primitive HPCs.

Abstract
Chimerism, defined as the co-existence of cells of different origin within the same organism, has received much attention in hematopoietic cell and organ transplantation because of the strict relationship between its establishment and the induction of specific tolerance. Traditional methods applied for chimerism detection, such as immunohistochemistry, cytogenetics, fluorescent-activated cell sorter analysis, and serological and biochemical testing, are limited by their sensitivity. We have established a highly sensitive molecular approach based on the amplification of the mitochondrial cytochrome B gene and tested its specificity and sensitivity level in six different mammalian species, including human, pig, mouse, rat, sheep and rabbit. Increased sensitivity of detection of specific amplification products was obtained by the non-radioactive Southern blot technique. This novel approach allows the detection of one cell against the background of 1 to 4 x 10(6) xenogenec cells and will be helpful for high-sensitivity analysis of donor cell engraftment after xenotransplantation procedures in these animal models.

Abstract
BACKGROUND Canine models of bone marrow and renal transplantation have provided important preclinical data relevant to developing novel therapeutic protocols for hematopoietic and solid organ transplantation in human beings. Nonmyeloablative transplantation has been shown to induce stable mixed hematopoietic chimerism in normal dogs and correct the phenotype of canine pyruvate kinase deficiency and Glanzman's thrombasthenia. In this study, we investigated the potential for inducing renal allograft tolerance using a nonmyeloablative bone marrow transplantation strategy that induces mixed chimerism in DLA-identical dogs. METHODS Reciprocal renal allografts were performed in 4 DLA-identical and 4 DLA-haploidentical dogs with nonmyeloablative conditioning (200 cGy total body irradiation [TBI]) and transient immunosuppression with cyclosporine (CSP) and mycophenolate mofetil (MMF) with and without simultaneous bone marrow transplantation. Two DLA-identical control dogs received reciprocal renal allografts without TBI or immunosuppression with CSP and MMF. Serum creatinine (Cr) concentration was monitored to assess renal allograft function. RESULTS The renal allografts were acutely rejected in the 2 DLA-identical dogs without TBI or immunosuppression. There was long-term (>1 year) renal allograft survival as evidenced by a normal (<2.0 mg/dL) serum Cr concentration in both the DLA-identical and DLA-haploidentical dogs that underwent 200 cGy TBI and transient immunosuppression with CSP and MMF either with or without simultaneous bone marrow transplantation. CONCLUSIONS Nonmyeloablative conditioning (200 cGy TBI) and transient immunosuppression with CSP and MMF induce renal allograft tolerance in DLA-identical and DLA-haploidentical dogs without donor/host mixed hematopoietic chimerism. These findings suggest it may be possible to induce tolerance to solid organ transplants without the need for chronic immunosuppressive therapy or stable hematopoietic chimerism in the setting of both DLA-matched and haploidentical transplants.

Abstract
The major goal of this work was to describe the in vitro generation of mature functional neutrophils derived from a canine enriched haematopoietic progenitor cell population. We have utilised lineage depletion by immunomagnetic selection to isolate a canine haematopoietic progenitor cell population. The physical, immunological, metabolical and morphological methodologies employed in this study have permitted us to isolate and define a cell population enriched in Rh-123low and CD34+ cells. Irradiated pre-established long-term bone marrow cultures (LTBMC) were utilised to determine the self-renewal ability of lineage negative (Lin-) cells, as well as their capacity to differentiate into mature functional neutrophils. The authors demonstrate for the first time that canine neutrophils derived from Lin- cells are able to produce oxyradicals, express a specific neutrophil surface antigen, and contain gelatinase granules. These characteristics enable them to migrate through basement membranes to act as a first line defence mechanism. The fact that these cells are able to differentiate into functional mature cells, and give rise to long-term culture-initiating cells (LTC-IC) after 35 days of culture, allows the authors to assure that the isolated canine enriched haematopoietic cell population exhibit functional characteristics, associated with primitive haematopoietic cells.

Abstract
Historically, the dog has been a valuable model for bone marrow transplantation studies, with many of the advances achieved in the dog being directly transferable to human clinical bone marrow transplantation protocols. In addition, dogs are also a source of many well-characterized homologues of human genetic diseases, making them an ideal large animal model in which to evaluate gene therapy protocols. It is generally accepted that progenitor cells for many human hematopoietic cell lineages reside in the CD34+ fraction of cells from bone marrow, cord blood, or peripheral blood. In addition, CD34+ cells are the current targets for human gene therapy of diseases involving the hematopoietic system. In this study, we have isolated and characterized highly enriched populations of canine CD34+ cells isolated from dogs 1 week to 3 months of age. Bone marrow isolated from 2- to 3-week-old dogs contained up to 18% CD34+ cells and this high percentage dropped sharply with age. In in vitro 6-day liquid suspension cultures, CD34+ cells harvested from 3-week-old dogs expanded almost two times more than those from 3-month-old dogs and the cells from younger dogs were also more responsive to human Flt-3 ligand (Flt3L). In culture, the percent and number of CD34+ cells from both ages of dogs dropped sharply between 2 and 4 days, although the number of CD34+ cells at day 6 of culture was higher for cells harvested from the younger dogs. CD34+ cells harvested from both ages of dogs had similar enrichment and depletion values in CFU-GM methylcellulose assays. Canine CD34+/Rho123lo cells expressed c-kit mRNA while the CD34+/Rhohi cells did not. When transplanted to a sub-lethally irradiated recipient, CD34+ cells from 1- to 3-week-old dogs gave rise to both myeloid and lymphoid lineages in the periphery. This study demonstrates that canine CD34+ bone marrow cells have similar in vitro and in vivo characteristics as human CD34+ cells. In addition, ontogeny-related functional differences reported for human CD34+ cells appear to exist in the dog as well, suggesting pediatric CD34+ cells may be better targets for gene transfer than adult bone marrow. The demonstration of similarities between canine and human CD34+ cells enhances the dog as a large, preclinical model to evaluate strategies for improving bone marrow transplantation protocols, for gene therapy protocols that target CD34+ cells, and to study the engraftment potential of various cell populations that may contain hematopoietic progenitor cell activity.

Abstract
OBJECTIVE We focused on a small New World monkey, the common marmoset (Callithrix jacchus), to establish a nonhuman primate model of the treatment of hematological disorders. In this study, we developed the first monoclonal antibodies (MAbs) against marmoset CD34 and tested the in vitro and in vivo hemopoietic activity of cell populations isolated using one of these MAbs. METHODS AND RESULTS Marmoset cDNA encoding a human CD34 homologue was cloned from bone marrow (BM)-derived RNA using reverse transcription polymerase chain reaction and rapid amplification of cDNA ends. The amino acid sequence of the marmoset CD34 had 81% homology with the human sequence. Five mouse MAbs were raised against marmoset CD34 transfectant. One representative MAb, MA24 (IgM), reacted with approximately 0.5 to 1% of BM mononuclear cells (MNCs), where the colony-forming unit granulocyte/macrophage (CFU-GM) was enriched approximately 11- to 75-fold as compared with the whole BM MNCs. Multilineage differentiation of marmoset CD34+ cells in NOD/SCID mice was confirmed by flow cytometry 1 month after xenotransplantation. CONCLUSION These results demonstrated that MA24 is useful for the analysis and enrichment of hematopoietic progenitor cells in the marmoset model for preclinical experiments.

Abstract
AIM: To observe whether the CD117-CD45- bone marrow cell can differentiate into the cells with characters of hepatocyte by the stimulation of hepatocyte growth factor (HGF)and fibroblast growth factor-4 (FGF4), and to explore the acting mechanism of the growth factors.
METHODS: Bone marrow cells were from the stern or ilium of 4 healthy volunteers between 4-40 years old. CD117-CD45- bone marrow cells separated by magnetic cell sorting method, cultured in DMEM medium with FGF4, HGF, FGF4+ HGF or no growth factor were divided into four groups: groups A, B, C, and D accordingly. Cells were collected on d 0, 7, 14, 21, and 28 for detecting the hepatocyte markers: AFP, CK18, albumin by immunocytochemistry, glycogen by PAS staining and c-met, FGFR2 mRNA by RT-PCR.
RESULTS: The specific markers of hepatocyte were positive in groups A, B and C but not in group D. C-met and FGFR2 mRNA expressed at a low level in the cells newly isolated or cultured in the medium without growth factor, but at increasing level after cutured with growth factor.
CONCLUSION: HGF and FGF4 can induce CD45-CD117- differentiate into hepatocyte-like cells. The effect of growth factor on cell differentiation is probably by the positive regulation between the growth factor and its receptor.

Abstract
Dogs represent both an important veterinary species and a convenient model for allogeneic hematopoietic stem cell transplantation. Even though anti-canine CD34 antibodies have recently become available, little is known about hematopoietic lineages in dogs, partially because CD34- cells have been ignored in all analyses performed so far. In this study, we have focused on the bone marrow mononuclear compartment to provide an additional piece of information on the phenotype of CD34+ progenitors and to identify the dominant CD34- population. We have shown that, in contrast to the adults, mature lymphocytes are scarce in neonatal dog bone marrow. Using cross-reactive antibodies against CD79alpha we have shown that the B lineage of hematopoiesis strongly prevails. CD34+ cells were shown to be positive for MHC class II and SWC3, a member of the signal regulatory protein family.
