Abstract
OBJECTIVE Establishment of a stable umbilical cord blood CD34(+) (UCB CD34(+)) cell culture system and identification of the cells in the cobblestone area differentiated from UCB CD34(+) long-term culture cells. MATERIALS AND METHODS Human UCB CD34(+) cells were cultured on MS-5 mouse stroma cells in the presence of stem cell factor (SCF), flt-3 ligand (FL), and thrombopoietin (TPO) for 4 to 16 weeks. Cells in the culture medium and in the cobblestone area were collected and characterized by flow cytometry and microscopy. RESULTS CD34(+) cells were stably expanded by culturing on MS-5 stroma cells in the presence of SCF, FL, and TPO for more than 4 months. Cells highly expressing CD117 (c-kit) appeared in the cobblestone area after 2 weeks and stably expanded. Isolation of cells highly expressing CD117 by fluorescence-activated cell sorter (FACS) revealed the cells were tryptase-positive and Fc epsilon receptor 1-negative mast cells. They showed typical mast cell morphology and released histamine upon stimulation by substance P or compound 48/80 in vitro. CONCLUSION Human UCB CD34(+) cells were stably expanded on MS-5 stroma cells in the presence of SCF, FL, and TPO. Under this condition, multipotent CD34(+) cells and mast cells differentiated from UCB CD34(+) cells were expanded in the cobblestone area. The expanded mast cells showed histamine release after substance P or compound 48/80 stimulation. These human mast cells will be useful as a source of human cells for evaluating the allergic effects of drugs.

Abstract
The study of the human hematopoietic system would be facilitated by availability of a relevant animal model. Because the medullar microenvironment is made of different types of cells, interactions between hematopoietic cells and stromal cells are difficult to analyze in detail. As an approach for establishing an in vivo model to dissect these interactions, we grafted murine bone marrow fibroblastic cells (MS-5 cell line) with hematopoietic cells into the kidney capsule of syngenic mice. To identify the origin of cells present in the graft, we used green fluorescent protein-stable transfected MS-5 cells for the transplantation. To analyze the evolution of stromal cells and identify hematopoietic cells able to develop in these conditions, we performed morphology, histochemistry, and immunohistology on tissue sections at different times after transplantation. When injected alone, MS-5 cells differentiate into adipocytes. When injected with a bone marrow suspension or with isolated CD45+ cells (leukocytes), the stromal cells keep their fibroblastic morphology and their alkaline phosphatase expression and sustain granulopoiesis. When injected with hematopoietic stem cells called c-kit+ Sca-1+ Lin- suspension, clusters of hematopoietic cells are also observed: They do not present any granulopoietic activity and do not belong to B or T population nor to erythroid lineage. They are quiescent, induce bone marrow recovery and survival of lethally irradiated recipients, are able to form macroscopic colonies in the spleen, and are able to form very few colonies in vitro, suggesting that they are hematopoietic stem cells. In conclusion, our results show that reticular fibroblastic stromal cells MS-5 sustain the survival of stem cells and are not able to induce their differentiation. However, they can control differentiation, proliferation, and/or survival of hematopoietic cells engaged in myeloid lineage.

Abstract
Mast cells (MCs) are tissue resident, hematopoietic stem cells-derived elements, distributed throughout the body. They are the pivotal mediating cells of allergic reactions. In addition, in mice, MCs play a critical role in the defense against several pathogens, such as bacteria, parasites and viruses. Whereas the biology of rodent and human MCs has been extensively studied using in vitro derived populations, the role of MCs in pigs has not yet been evaluated, given the very low availability of pure porcine MCs populations. In the present report, we describe an original method to obtain continuous factor-dependent normal pig MCs (PMC) lines from fetal hematopoietic progenitors. These Stem Cell Factor (SCF) and Interleukin-3- (IL-3)-dependent PMC lines retain their capacity to growth after conventional freezing methods and exhibit most of the morphological and biochemical properties of normal, although immature, MCs, including metachromatic granules containing sulfated polysaccharides, the expression of c-kit and high-affinity IgE receptors (FcepsilonRI), and the ability to store histamine that is released upon cross-linking of FcepsilonRI. In vitro derived PMC lines might thus be valuable tools to further investigate the reactivity of these elements towards several parasites frequently encountered in pig, such as, but not limited to, Ascaris suum, Trichinella spiralis or Trichuris suis, or towards antigens derived from these pathogens.

Abstract
OBJECTIVES Limited attention has been given to the role mast cells may play in periodontal diseases. BACKGROUND Mast cells are indeed found abundantly below and within several types of mucosal epithelia. On the basis of their proteinase content, mast cells are divided into connective tissue (CT) and mucosal phenotypes. The CT phenotype contains both tryptase and chymase (MC(TC)), while the mucosal phenotype contains only tryptase (MC(T)). The in vivo significance of different mast cell phenotypes has not yet been fully established. Mast cells are able to phagocytose, process and present antigens as effectively as macrophages. RESULTS Recently mast cells were found in high numbers in chronically inflamed gingival tissue taken from patients with chronic marginal periodontitis (CMP). The number of mast cells was found to be even higher in HIV(+) patients with CMP. Furthermore, mast cells also express strongly matrix metalloproteinases (MMPs), which are key enzymes in degradation of gingival extracellular matrix. Mast cells may release preformed cytokines directing local innate and adaptive immune responses. The present review will focus on possible roles for mast cells in periodontal diseases. CONCLUSIONS We certainly feel that this is a key cell in inflamed periodontal tissue and its role in periodontitis needs to be revisited.

Abstract
Mast cells (MC), which are tissue-resident cells found widely distributed in the body, are derived from primitive hematopoietic cells. MC produce a variety of biologically active substances such as histamine, proteases, lipid derivatives and numerous cytokines and chemokines in response to immunologic or non-immunologic stimuli. Of interest, it has been reported that rodent MC can also be a source of nitric oxide (NO) derivatives, that they synthesize spontaneously, or only after activation, depending on their subtype. This synthesis appears to be under the control of the expression of the inducible isoform of the nitric oxide synthase (iNOS) and of the constitutive neuronal NOS (nNOS). MC might thus be able to influence the survival and functions of other types of NO-sensitive cells in close vicinity. Apart from being a source of NO, MC can also be the target for NO and its derivatives. Indeed, survival and reactivity of rodent MC is influenced by NO derivatives produced by MC themselves or by other cellular elements in close contact with the MC in tissues. By contrast, the existence of such mechanisms of cross-talk between MC and NO remains poorly documented in humans. If evidence are supplied in favor of such relationship, pharmacological modulation by agents acting at the level of the NO pathway might be of interest in order to regulate the functions of MC in immunologic, neoplastic, inflammatory and other conditions.

Abstract
Recent studies have implicated rodent mast cells in the innate immune response to infectious bacteria. We report that cord blood-derived human mast cells (CBHMC) obtained from culture of cord blood progenitors phagocytozed and killed various gram-negative and gram-positive bacteria and simultaneously released considerable amounts of tumor necrosis factor alpha. Overall, the extent of the endocytic and exocytic response of CBHMC correlated with the number of adherent bacteria. Thus, human mast cells are intrinsically capable of mediating microbial recognition and of actively contributing to the host defense against bacteria.

Abstract
Stem cell factor (SCF) is a major cytokine regulator of mast cell growth and function. The present study demonstrates that human mast cells are able to produce SCF. Constitutive synthesis of SCF mRNA was seen in the mast cells isolated from human lung and skin by RT-PCR. This was confirmed by in situ hybridization in conjunctival mast cells of both tryptase-only (MCT) and tryptase/chymase (MCTC) subsets. SCF protein product was found in conjunctival MCT and MCTC mast cells by immunohistochemistry. Soluble SCF protein was detected in the culture supernatant of isolated lung mast cells by ELISA, and cross-linkage of IgE receptor (Fc epsilon-RI) on the lung mast cells in culture did not alter SCF mRNA expression, or the secreted soluble SCF protein. This was consistent with the finding that levels of SCF mRNA expression in conjunctival mast cells were similar between normal subjects and patients with seasonal allergic conjunctivitis (SAC). This study shows that human mast cells themselves are a cellular source of SCF, as well as being target cells for this growth factor. SCF may regulate mast cell growth and function via both paracrine and autocrine mechanisms. The production of SCF by mast cells may be regulated via mechanisms other than IgE receptor-mediated pathways.

Abstract
Ex vivo expanded CD34+ progenitor cells from fresh or cryopreserved primate bone marrow, induced to granulocytic differentiation with growth factors, were investigated to determine whether myeloid cells produced in liquid cultures have the normal biologic functions needed for the treatment of patients with neutropenia following high-dose chemotherapy or therapeutic or accidental radiation exposure. Human and simian (baboons or macaques) CD34+ cells were cultured with granulocyte-colony stimulating factor (G-CSF), stem cell factor (SCF), interleukin-1 (IL-1), IL-3, and IL-6, and assessed at 14 days of culture for their capacity to respond to different functional tests. Immunostaining revealed that human ex vivo expanded cells contained myeloperoxydase (MPO, 82% +/- 8%) and lactoferrin (LF, 30% +/- 6%) in their granules. Maturation of cultured cells was associated with stimulated chemotactic responsiveness and respiratory burst activity (superoxide anion and hydrogen peroxide production) in expansions from human, baboon, and macaque CD34+ progenitor cells. Mature cells obtained from ex vivo expansion of selected cryopreserved human bone marrow CD34+ cells presented reduced but significant functional activities (chemotactic responsiveness and hydrogen peroxide production) when compared with human peripheral blood neutrophils. The validation of nonhuman primate ex vivo expansion systems may permit their use as models of irradiation. The feasibility of ex vivo expansion from cryopreserved bone marrow cell samples may offer considerable opportunity for banking bone marrow for autologous transfusion.

Abstract
In the presence of interleukin-3 and interleukin-5, eosinophil precursors from human umbilical cord blood mononuclear cells were regularly differentiated into mature eosinophil-like cells expressing normal morphology and cyanide-resistant peroxidase. O2- production and [Ca2+]i rise were measured in these in vitro differentiated eosinophils after fMLP stimulation; with dihydrorhodamine-123 and fura-2, respectively. Umbilical cord blood-derived eosinophils responded to fMLP (0.01 nM to 3 microM) with a concentration-dependent production of O2- (EC50 = 63.1 +/- 17.2 nM; Emax = 71.0 +/- 6.2 pmol/min/10(6) cells). O2- production was correlated with an fMLP concentration-dependent increase in [Ca2+]i (EC50 = 32.5 +/- 14.9 nM; Emax = 200.0 +/- 23.9 nM). These results indicate that human umbilical cord blood-derived eosinophils demonstrate functional characteristics similar to adult human peripheral blood eosinophils after activation by fMLP. Therefore, the large numbers of eosinophils (2-3 x 10(6)/ml cord blood) which can be obtained by culture of human cord blood mononuclear cells may serve as a useful model for future studies which will provide insight into the pathogenesis of diseases associated with eosinophils.

Abstract
Recent in vitro analyses of human UCB have demonstrated the potential of UCB as a source for haematopoietic stem and progenitor cell harvest. Clinical data have further indicated that UCB can be given in vivo to fully and partially HLA-matched siblings or non-familial recipients for marrow reconstitution in genetic disorders as well as malignancies. In comparison to adult peripheral blood, UCB displayed decreased immune responses to alloantigens and was enriched in the numbers of CD34+ progenitor cells with high proliferative and long-term marrow reconstituting potential. Cord blood banks now store large transplantable resources of UCB that are analysed with respect to immunological parameters. Cryopreserved UCB cells may fill the gap in finding a stem-cell transplant for patients who lack a matched related or unrelated donor when a bone marrow transplant is needed.
