Cocaine metabolite kinetics in the newborn. (1/4377)

The study goal was to determine the half-life elimination of cocaine and benzoylecgonine (BZE) in the newborn. Three 0.3-mL blood samples were collected during the first day of life. Urine was collected once daily. Cocaine and BZE concentrations were determined by gas chromatography-mass spectrometry. An extraction method was developed for measuring low concentrations of cocaine and BZE in small (0.1 mL) blood samples. Cocaine had a half-life of 11.6 h in one subject. The half-life of BZE during the first day of life, based on blood data in 13 subjects, was 16 h (95% confidence interval [CI], 12.8 to 21.4 h). The half-life of BZE during the first week of life, based on urine data in 16 subjects, was 11.2 h (95% CI, 10.1 to 11.8 h). The novel extraction method for small blood sample volumes should be applicable to other basic drugs.  (+info)

Cortisol in fetal fluids and the fetal adrenal at parturition in the tammar wallaby (Macropus eugenii). (2/4377)

Glucocorticoid hormones may play a critical role in initiating parturition in tammar wallabies. In this study, we investigated the concentration of cortisol in fetal fluids and cortisol production by fetal adrenals over the last 3 days of the 26-day pregnancy and within 24 h postpartum. The fetal adrenals almost doubled in size between Days 24 and 26 of pregnancy, and their cortisol content increased over 10-fold during this period, from 10 pg to over 100 pg per adrenal pair. After birth, neonatal adrenals continued to grow, but cortisol content fell dramatically to 20 pg. The prepartum increase in adrenal cortisol was reflected by a substantial rise in cortisol concentrations in yolk sac fluid, allantoic fluid, and fetal blood, which were below 10 ng/ml on Day 24 and rose to over 40 ng/ml by Day 26. Cortisol concentrations in neonatal blood decreased postpartum, mirroring decreased cortisol content in neonatal adrenals. Cortisol production by the fetal adrenal was stimulated in vitro by ACTH and prostaglandin E2, suggesting that the in vivo increase may be stimulated by release of ACTH from the fetal hypothalamic-pituitary axis and prostaglandin E2 from the placenta. These results indicate that increasing cortisol production by the fetal adrenal is a characteristic of late pregnancy in the tammar wallaby and support the suggestion that fetal cortisol may trigger the initiation of parturition in this marsupial species.  (+info)

Delay of preterm delivery in sheep by omega-3 long-chain polyunsaturates. (3/4377)

A positive correlation has been shown between dietary intake of long-chain omega-3 fatty acids in late pregnancy and gestation length in pregnant women and experimental animals. To determine whether omega-3 fatty acids have an effect on preterm labor in sheep, a fish oil concentrate emulsion was continuously infused to six pregnant ewes from 124 days gestational age. At 125 days, betamethasone was administered to the fetus to produce preterm labor. Both the onset of labor and the time of delivery were delayed by the fish oil emulsion. Two of the omega-3-infused ewes reverted from contractions to nonlabor, an effect never previously observed for experimental glucocorticoid-induced preterm labor in sheep. Maternal plasma estradiol and maternal and fetal prostaglandin E2 rose in control ewes but not in those infused with omega-3 fatty acid. The ability of omega-3 fatty acids to delay premature delivery in sheep indicates their possible use as tocolytics in humans. Premature labor is the major cause of neonatal death and long-term disability, and these studies present information that may lead to a novel therapeutic regimen for the prevention of preterm delivery in human pregnancy.  (+info)

Phenotypic and functional evidence for the expression of CXCR4 receptor during megakaryocytopoiesis. (4/4377)

The identification of stromal cell-derived factor (SDF)-1alpha as a chemoattractant for human progenitor cells suggests that this chemokine and its receptor might represent critical determinants for the homing, retention, and exit of precursor cells from hematopoietic organs. In this study, we investigated the expression profile of CXCR4 receptor and the biological activity of SDF-1alpha during megakaryocytopoiesis. CD34(+) cells from bone marrow and cord blood were purified and induced to differentiate toward the megakaryocyte lineage by a combination of stem-cell factor (SCF) and recombinant human pegylated megakaryocyte growth and development factor (PEG-rhuMGDF). After 6 days of culture, a time where mature and immature megakaryocytes were present, CD41(+) cells were immunopurified and CXCR4mRNA expression was studied. High transcript levels were detected by a RNase protection assay in cultured megakaryocytes derived from cord blood CD34(+) cells as well as in peripheral blood platelets. The transcript levels were about equivalent to that found in activated T cells. By flow cytometry, a large fraction (ranging from 30% to 100%) of CD41(+) cells showed high levels of CXCR4 antigen on their surface, its expression increasing in parallel with the CD41 antigen during megakaryocytic differentiation. CXCR4 protein was also detected on peripheral blood platelets. SDF-1alpha acts on megakaryocytes by inducing intracellular calcium mobilization and actin polymerization. In addition, in in vitro transmigration experiments, a significant proportion of megakaryocytes was observed to respond to this chemokine. This cell migration was inhibited by pertussis toxin, indicating coupling of this signal to heterotrimeric guanine nucleotide binding proteins. Although a close correlation between CD41a and CXCR4 expession was observed, cell surface markers as well as morphological criteria indicate a preferential attraction of immature megakaryocytes (low level of CD41a and CD42a), suggesting that SDF-1alpha is a potent attractant for immature megakaryocytic cells but is less active on fully mature megakaryocytes. This hypothesis was further supported by the observation that SDF-1alpha induced the migration of colony forming unit-megakaryocyte progenitors (CFU-MK) and the expression of activation-dependent P-selectin (CD62P) surface antigen on early megakaryocytes, although no effect was observed on mature megakaryocytes and platelets. These results indicate that CXCR4 is expressed by human megakaryocytes and platelets. Furthermore, based on the lower responses of mature megakaryocytes and platelets to SDF-1alpha as compared with early precursors, these data suggest a role for this chemokine in the maintenance and homing during early stages of megakaryocyte development. Moreover, because megakaryocytes are also reported to express CD4, it becomes important to reevaluate the role of direct infection of these cells by the human immunodeficiency virus (HIV)-1 in HIV-1-related thrombocytopenia.  (+info)

Detection of antibody to bovine syncytial virus and respiratory syncytial virus in bovine fetal serum. (5/4377)

Batches of commercial fetal bovine serum, described by the suppliers as antibody-free, all contained antibody to bovine syncytial virus (BSV) when tested by indirect immunofluorescence. Antibody to bovine respiratory syncytial virus (RSV) was not detected in these sera. Twenty-four percent of individual fetal bovine sera contained antibody to BSV, and 14% contained antibody to RSV when tested by indirect immunofluorescence. BSV antibody titers in fetal sera from dams with high BSV antibody levels were variable but always higher than RSV antibody titers. Radial immunodiffusion studies with BSV-positive sera revealed the presence of immunoglobulin M (IgM), IgG, and IgA, but the quantity of these immunoglobulins was not directly related to the BSV antibody titers. The evidence suggests that the antibody present in fetal sera arose as the result of infection rather than from maternal transfer across the placenta.  (+info)

Early ontogeny of monocytes and macrophages in the pig. (6/4377)

Prenatal development of cord blood monocytes and tissue macrophages was studied in pig foetuses by immunophenotyping and functional assays. The function of peripheral blood monocytes was compared in germ-free and conventional piglets. First macrophages were identified by electron microscopy in foetal liver on the 25th day of gestation. Monoclonal antibodies against porcine CD45 and SWC3 antigens were used for flow cytometric identification of myelomonocytic cells in cell suspensions prepared from the yolk sac, foetal liver, spleen and cord blood. Leukocytes expressing the common myelomonocytic antigen SWC3 were found in all organs studied since the earliest stages of development. Opsonized zymosan ingestion assay was used to determine the phagocytic capacity of foetal mononuclear phagocytes isolated from cord blood, liver and spleen. In the foetal liver, avid phagocytosis of apoptic cells had been found to occur before cells were able to ingest zymosan in vitro. The first cells capable of ingesting zymosan particles were found on the 40th day of gestation in umbilical blood and 17 days later in foetal spleen and liver. Their relative proportion increased with age. Cord blood monocytes and peripheral blood monocytes in germ-free piglets had low oxidatory burst activity as shown by iodonitrophenyl tetrazolium reduction assay. A remarkable increase of oxidatory burst activity was observed in conventional piglets, probably due to activation of immune mechanisms by the microflora colonizing gastrointestinal tract.  (+info)

Laboratory assay reproducibility of serum estrogens in umbilical cord blood samples. (7/4377)

We evaluated the reproducibility of laboratory assays for umbilical cord blood estrogen levels and its implications on sample size estimation. Specifically, we examined correlation between duplicate measurements of the same blood samples and estimated the relative contribution of variability due to study subject and assay batch to the overall variation in measured hormone levels. Cord blood was collected from a total of 25 female babies (15 Caucasian and 10 Chinese-American) from full-term deliveries at two study sites between March and December 1997. Two serum aliquots per blood sample were assayed, either at the same time or 4 months apart, for estrone, total estradiol, weakly bound estradiol, and sex hormone-binding globulin (SHBG). Correlation coefficients (Pearson's r) between duplicate measurements were calculated. We also estimated the components of variance for each hormone or protein associated with variation among subjects and variation between assay batches. Pearson's correlation coefficients were >0.90 for all of the compounds except for total estradiol when all of the subjects were included. The intraclass correlation coefficient, defined as a proportion of the total variance due to between-subject variation, for estrone, total estradiol, weakly bound estradiol, and SHBG were 92, 80, 85, and 97%, respectively. The magnitude of measurement error found in this study would increase the sample size required for detecting a difference between two populations for total estradiol and SHBG by 25 and 3%, respectively.  (+info)

Long-term fetal microchimerism in peripheral blood mononuclear cell subsets in healthy women and women with scleroderma. (8/4377)

Fetal CD34(+) CD38(+) cells have recently been found to persist in maternal peripheral blood for many years after pregnancy. CD34(+) CD38(+) cells are progenitor cells that can differentiate into mature immune-competent cells. We asked whether long-term fetal microchimerism occurs in T lymphocyte, B lymphocyte, monocyte, and natural-killer cell populations of previously pregnant women. We targeted women with sons and used polymerase chain reaction for a Y-chromosome-specific sequence to test DNA extracted from peripheral blood mononuclear cells (PBMC) and from CD3, CD19, CD14, and CD56/16 sorted subsets. We also asked whether persistent microchimerism might contribute to subsequent autoimmune disease in the mother and included women with the autoimmune disease scleroderma. Scleroderma has a peak incidence in women after childbearing years and has clinical similarities to chronic graft-versus-host disease that occurs after allogeneic hematopoietic stem-cell transplantation, known to involve chimerism. Sixty-eight parous women were studied for male DNA in PBMC and 20 for PBMC subsets. Microchimerism was found in PBMC from 33% (16 of 48) of healthy women and 60% (12 of 20) women with scleroderma, P =.046. Microchimerism was found in some women in CD3, CD19, CD14, and CD56/16 subsets including up to 38 years after pregnancy. Microchimerism in PBMC subsets was not appreciably more frequent in scleroderma patients than in healthy controls. Overall, microchimerism was found in CD3, CD19, and CD14 subsets in approximately one third of women and in CD56/16 in one half of women. HLA typing of mothers and sons indicated that HLA compatibility was not a requirement for persistent microchimerism in PBMC subsets. Fetal microchimerism in the face of HLA disparity implies that specific maternal immunoregulatory pathways exist that permit persistence but prevent effector function of these cells in normal women. Although microchimerism in PBMC was more frequent in women with scleroderma than healthy controls additional studies will be necessary to determine whether microchimerism plays a role in the pathogenesis of this or other autoimmune diseases.  (+info)

IND Applications for Minimally Manipulated, Unrelated Allogeneic Placental/Umbilical Cord Blood Intended for Hematopoietic and Immunologic Reconstitution in Patients with Disorders Affecting the Hematopoietic System, CBER, Biologics
Background: Cell therapy is a potential therapeutic approach for neurodegenerative disorders. Human umbilical cord bloodderived mesenchymal stem cells (hUCB-MSCs) are an appropriate source of stem cells for use in various cell-based therapies. Objectives: In this study, we examined a real-time PCR approach for neural differentiation of hUCB-MSCs in vitro. Materials and Methods: MSCs were cultured in DMEM medium supplemented with 10% FBS in a humidified incubator equilibration at 5% CO2 and 37°C. For the neural differentiation of MSCs, the DMEM was removed and replaced with pre-induction media (retinoic acid [RA], basic fibroblast growth factor [bFGF], and epidermal growth factor [EGF]) and basal medium for two days. They were then cultured in nerve growth factor (NGF), 3-isobutyl-1-methylxanthine (IBMX), ascorbic acid (AA), and basal medium for six days. We also monitored the expression of markers for neural differentiation with real-time PCR. Results: The results of real-time PCR showed that the
Although in several studies IL15 was an effective cytokine that could induce eradication of experimental tumors (8-11), application of MSCs to serve as a vehicle for delivering IL15 to cancer has not been reported so far. In this study, we investigated the development of IL15 gene modified MSCs for tumor therapy strategy. The hypothesis is that MSCs secreting IL15, when injected into tumor-bearing mice, would specifically migrate to and enrich in the tumor site, and exert a potent antitumor immunity. The results presented here support feasibility of this strategy.. Accumulative evidences demonstrate that MSCs are able to migrate to tumor site or inflammatory region (31, 32). In this study, histology analysis showed accumulation of MSCs in tumor site, but not in other organ sites. Higher level of IL15 was observed in tumor site, and systemic level of IL15 was significantly lower than tumor local level of IL15. These findings indicated that MSC-IL15 was able to specific home to tumor tissue, and a ...
Front Pharmacol. 2017 Sep 8 Human Umbilical Cord Blood Cell Transplantation in Neuroregenerative Strategies. Galieva LR1, Mukhamedshina YO1,2, Arkhipova SS1, Rizvanov AA1. Author information Abstract At present there is no effective treatment of pathologies associated with the death of neurons and glial cells which take place as a result of physical trauma or ischemic lesions of the nervous system. Thus, researchers have high hopes for a treatment based on the use of stem cells (SC),
Diabetes mellitus (DM) instigates a cascade of events leading to vascular damage and poor recovery after ischemic stroke. Our previous studies have found that treatment of stroke with bone-marrow-stromal cells initiated at 24h after stroke improves functional recovery in non-DM rats, but not in DM rats. Effective therapy for stroke in the non-DM population may not necessarily transfer to the DM population, prompting the need to develop therapeutic approaches specifically designed to reduce neurological deficits after stroke in the DM population. In this study, we hypothesize that treatment of stroke with human umbilical cord blood cells (HUCBCs) promotes neurorestorative effect in DM rats.. Methods: Type one DM (T1DM) was induced with a single injection of streptozotocin (60 mg/kg, ip) to adult male Wistar rats. These rats were subjected to 2h MCAo and were randomized to intravenous injection via tail-vein with: 1) phosphate-buffered saline control; 2) HUCBCs (5x106) at 24 hours after MCAo. A ...
In this study, after 21 days of ceasing CCl 4 , both placebo-treated and untreated cirrhotic mice showed reduced liver damage as indicated by a decrease of AST/ALT index, recovery of histology, and reduction of fibrosis-related gene expression. Presumably, the liver of these mice were capable of self-regeneration. The cause of the self-regeneration has been explained by the ceasing of CCl 4 administration during the 21 days of treatment. Other studies have shown similar results to our study Carvalho et al., 2008 Kuo et al., 2008 .. However, our study uniquely demonstrates that stem cell treatment in cirrhotic mice was better for restoring liver function and histology (significantly better than placebo treatment). The effects of stem cell treatment in our mouse model of liver cirrhosis may be attributed to stem cell immunomodulation, stem cell homing and differentiation, and secreted cytokines Berardis et al., 2015 .. In terms of stem cell therapy for liver cirrhosis, there are several routes for ...

Robust and large-scale expansion of umbilical cord blood stem cells in vitro is necessary for widening the usage of transplantation therapies for the treatment of hematological and immune diseases. The lack of understanding of the complex inter-cellular networks regulating stem cell fate in culture explains the low success met so far for the ex vivo expansion of hematopoietic stem cells. The development of a mathematical model of in vitro hematopoiesis coupled with gene expression profiling led to predictions about the secreted factors that play a crucial role in regulating hematopoietic stem cell self-renewal in culture. We tested 18 putative molecules predicted to display effects on primitive progenitor (Long-Term Culture-Initiating Cell; LTC-IC) output, functionally validating three stimulators (VEGF, PDGF, EGF) and three inhibitors (TGFβ, CCL4, CXCL10). Combinatorial studies with the stimulatory molecules showed less-than additive effects, perhaps related to redundant signaling mechanisms. Small
Umbilical cord blood (UCB) is an alternative hematopoietic stem cell (HSC) source that can ameliorate several diseases through transplantation. The purpose of this project is to analyze clinical studies comparing HSCs from a single cord blood unit (CBU) to HSCs from bone marrow, and to explore methods of increasing limited amounts of HSCs. It was found that UCB transplantation in adults is a viable method when a matched bone marrow transplant cannot be identified. Further clinical studies using two CBUs suggest better engraftment and lower risk of relapse. However, double cord blood transplantation has been faced with the challenge of single unit dominance in most studies. Ex vivo expansion of UCB HSCs is another promising method to overcome limited HSC counts.
CD34+ cells were isolated from a total of 27 cord blood samples, and the number of MNCs as well as CD34+ cells was analyzed in a Neubauer chamber. As shown in Table 1, the concentration of CD34+ cells was 28 cells/mm3 of cord blood (yield after Ficoll and MACS procedure). The purity of this cell fraction was 93.2 ± 3.6% (87-99%; N = 10). Since 22.2 ± 11.3% (12.5-50.6%) of the CD34+ cells were dead, the average frequency of viable CD34+ among total cells was 71.0 ± 13.1% (39.4-86.5%).. CD34+ cells were cultured with three combinations of growth factors (Figure 1). With TPO + FL + KL, the average increase in cell number in 9 samples studied was 3.55 ± 1.6-fold after 7 days of culture. Only 1 sample (3.a) showed a 0.56-fold decrease in cell number on day 4, but by day 7 the number of the cells in this sample had increased.

Although recent studies have demonstrated the in vitro hepatic differentiation potential of mesenchymal stem cells (MSCs), the evidence supporting the in vivo engraftment of MSCs, hepatic differentiation and improvement of hepatic function is still lacking. We investigated in vivo hepatic differentiation potential and therapeutic effect of cord blood derived-MSCs (CBMSCs) transplantation in a cirrhotic rat model. CBMSCs (2x106) were infused in Wistar rats with thioacetamide-induced chronic liver injury. Biochemical markers, liver fibrosis and engraftment of CBMSCs were assessed. Infused CBMSCs were detected in the perivascular or fibrous region of the liver and did not acquire mature hepatic phenotypes. There was no difference in biochemical markers and in the area of liver fibrosis between the experimental and placebo groups. After infusion of CBMSCs in our experimental cirrhotic rat model we did not observe an improvement of liver function and liver fibrosis. Inversely, CBMSCs could have a ...

With the goal of deriving clinically safe USSCs, we aimed to culture established USSCs in the serum- and animal component-free medium, USSC growth mediumACF. We observe that USSCs continue to proliferate in USSC growth mediumACF, but after one to three passages, the cells aggregate and grow in suspension as spheres. We show that spheres can be dissociated and can continue to grow for five passages, as long as they are dissociated before the sphere becomes cystic. We also show the spheres can revert to monolayer growth when provided with extracellular matrix support or when plated in medium containing fetal calf serum. Cells passaged in USCC growth mediumACF maintained their gene expression profile as judged by Sox2, Brachyury, Pax6 and Gata6 expression. Cells also maintained their capacity to form bone-like Alizarin red positive cells, SPC positive epithelial cells and β-tubulin III positive neuronal cells after directed differentiation. This is the first report of a serum-free medium that ...

Although pharmacological methods for treating AD have been discovered, none significantly delay the progression of the disease. However, cell transplantation research using animals modeled with AD has indicated that human umbilical cord blood cells (HUCBCs) can ameliorate some cognitive deficits and reduce the effects of the amyloid-beta (Aβ) plaques, one of the physiological hallmarks of AD, comprised of peptides of 36-43 amino acids. However, the role that HUCBCs play in Aβ clearance has yet to be elucidated ...

AU - MacArdle, Peter J.. PY - 2000/1/1. Y1 - 2000/1/1. N2 - Differential expression of the costimulator molecules CD40 and CD154 on neonatal lymphocytes may be one explanation for limited T-dependent antibody responses in human neonates. CD40 was expressed at similar levels on resting B cells from adults, young children (2-20 months of age) or cord blood. CD40 expression was higher on cord blood B cells compared to adult B cells after stimulation with PMA and ionomycin, but similar on adult and cord blood B cells activated by CD3-stimulated T cells. In contrast to previous reports, cord blood T cells stimulated with PMA and ionomycin expressed adult levels of CD154 initially, but this expression was more transient on cord blood T cells. When adult and cord blood mononuclear cells were stimulated with CD3 mAb, T ...

Diabetes mellitus (DM) is a high risk factor for stroke and leads to more severe vascular and white-matter injury than stroke in non-DM. We tested the neurorestorative effects of delayed human umbilical cord blood cell (HUCBC) treatment of stroke in type-2 diabetes (T2DM). db/db-T2DM and db/+-non-DM mice were subjected to distal middle cerebral artery occlusion (dMCAo) and were treated 3 days after dMCAo with: (a) non-DM + Phosphate buffered saline (PBS); (b) T2DM + PBS; (c) T2DM + naïve-HUCBC; (d) T2DM + miR-126(-/-) HUCBC. Functional evaluation, vascular and white-matter changes, neuroinflammation, and miR-126 effects were measured in vivo and in vitro. T2DM mice exhibited significantly decreased serum and brain tissue miR-126 expression compared with non-DM mice. T2DM + HUCBC mice exhibited increased miR-126 expression, increased tight junction protein expression, axon/myelin, vascular density, and M2-macrophage polarization. However, decreased blood-brain barrier leakage, brain hemorrhage, and miR

Human umbilical cord blood derived CD34+ stem cells are reported to mediate therapeutic effects in stroke animal models. Estrogen was known to protect against ischemic injury. The present study wished to investigate whether the protective effect of CD34+ cells against ischemic injury can be reinforced with complemental estradiol treatment in female ovariectomized rat and its possible mechanism. Experiment 1 was to determine the best optimal timing of CD34+ cell treatment for the neuroprotective effect after 60-min middle cerebral artery occlusion (MCAO). Experiment 2 was to evaluate the adjuvant effect of 17β-estradiol on CD34+ cell neuroprotection after MCAO. Experiment 1 showed intravenous infusion with CD34+ cells before MCAO (pre-treatment) caused less infarction size than those infused after MCAO (post-treatment) on 7T magnetic resonance T2-weighted images. Experiment 2 revealed infarction size was most significantly reduced after CD34+ + estradiol pre-treatment. When compared with no treatment

Umbilical cord blood-derived endothelial colony-forming cells (UCB-ECFC) show utility in neovascularization, but their contribution to osteogenesis has not been defined. Cocultures of UCB-ECFC with human fetal-mesenchymal stem cells (hfMSC) resulted in earlier induction of alkaline phosphatase (ALP) (Day 7 vs. 10) and increased mineralization (1.9x; p < .001) compared to hfMSC monocultures. This effect was mediated through soluble factors in ECFC-conditioned media, leading to 1.8-2.2x higher ALP levels and a 1.4-1.5x increase in calcium deposition (p < .01) in a dose-dependent manner. Transcriptomic and protein array studies demonstrated high basal levels of osteogenic (BMPs and TGF-βs) and angiogenic (VEGF and angiopoietins) regulators. Comparison of defined UCB and adult peripheral blood ECFC showed higher osteogenic and angiogenic gene expression in UCB-ECFC. Subcutaneous implantation of UCB-ECFC with hfMSC in immunodeficient mice resulted in the formation of chimeric human vessels, ...

There are several advantages of using umbilical cord blood stem cells over bone marrow stem cells for transplants (see Table 2). The first advantage is that umbilical cord blood is relatively easy to collect and process. Once considered a substance to be thrown away after a birth, now the cord blood can be easily saved. After it is saved and sent to a storage facility, the cord blood is quickly available for use within days to weeks after processing. In contrast, bone marrow stem cells can take much longer to find a match, collect the sample, and process. The process for bone marrow transplantation can take from weeks to months. The collection process for cord blood is not painful to either mother or child and can be done either prior to or after the delivery of the placenta (Gonzalez-Ryan, VanSyckle, Coyne, & Glover, 2000; Percer, 2009). Bone marrow transplants, on the other hand, require the donor to be hospitalized, anesthetized, and experience postcollection pain and discomfort. Thus, ...
Dendritic cells (DC) generated from human umbilical cord blood might replace patients' DC in attempts to elicit tumor-specific immune response in cancer patients. We studied the efficiency of transfection of human cord blood DC with plasmid DNA carrying the enhanced version of green fluorescent protein (EGFP) as a reporter gene, to test if nonviral gene transfer would be a method to load DC with protein antigens for immunotherapy purposes. Cord blood mononuclear cells were cultured in serum-free medium in the presence of granulocyte-monocyte colony stimulating factor (GM-CSF), stem cell factor (SCF) and Flt-3 ligand (FL), to generate DC from their precursors, and thereafter transfected by electroporation. Maturation of DC was induced by stimulation with GM-CSF, SCF, FL and phorbol myristate acetate (PMA). Transfected DC strongly expressed EGFP, but transfection efficiency of DC, defined as HLA-DR+ cells lacking lineage-specific markers, did not exceed 2.5%. Expression of the reporter gene ...
Hematopoiesis depends on the association of hematopoietic stem cells with stromal cells that constitute the hematopoietic microenvironment. The in vitro development of the endothelial cell from umbilical cord blood (UCB) is not well established and has met very limited success. In this study, UCB CD34(+) cells were cultured for 5 weeks in a stroma-free liquid culture system using thrombopoietin, flt3 ligand, and granulocyte-colony stimulating factor. By week 4-5, we found that firmly adherent fibroblast-like cells were established. These cells showed characteristics of endothelial cells expressing von Willebrand factor, human vascular cell adhesion molecule-1, human intracellular adhesion molecule-1, human CD31, E-selectin, and human macrophage. Furthermore, when comparing an ex vivo system without an established endothelial monolayer to an ex vivo system with an established endothelial monolayer, better expansion of total nucleated cells, CD34(+) cells, and colony-forming units ...

Deficient CD40 ligand (CD40L) expression by neonatal T cells has been proposed to explain the diminished Ig production by newborns. Therefore, we examined the expression and function of CD40L on activated neonatal CD4+ T cells isolated from cord blood. Anti-CD3 activation of neonatal T cells resulted in the expression of CD40L demonstrated with specific mAb or a soluble CD40.G1 construct. The level of expression was comparable to that of adult memory CD4+ T cells. In contrast, PMA and ionomycin induced only minimal CD40L expression by neonatal T cells, whereas adult memory T cells expressed CD40L comparably after stimulation with PMA and ionomycin or anti-CD3. The expression of CD40L was blocked by cyclosporine and prostaglandin E2 (PGE2). IL-2 IL-4 partially reversed the inhibition of CD40L expression by cyclosporine, and IL-2 reversed the inhibition by PGE2. CD40L expressed by neonatal T cells was functionally active, since neonatal T cell-dependent production of IgG4 and IgE was inhibited by ...
Seven cord blood (CB) units were tested for their capacity to repopulate irradiated NOD/SCID mice after one or two successive cryopreservation procedures. In primary transplants with frozen or refrozen CB cells we observed equivalent human colonies and percentages of human CD45+ cells, with multilineage engraftment. In secondary transplants flow cytometry and polymerase chain reaction for the a satellite region of chromosome 17 showed equivalent levels of human engraftment. Since CB units have, to date, mainly been stored in individual bags, our results suggest new options for optimizing the timing of infusions of expanded and non-expanded progenitors in transplants ...

BACKGROUND: Human umbilical cord blood (HUCB) is a possible alternative to bone marrow (BM) and mobilized peripheral blood (PB) for transplantation of hematopoietic progenitors. The aim of this study was to evaluate the phenotypic profile of CD34+ progenitors present in HUCB. MATERIALS AND METHODS: A flow cytometric analysis was performed on 20 HUCB samples, using a large panel of monoclonal antibodies recognizing different lineage or activation antigens, in double labeling with CD34. RESULTS: A toal of 13,897 +/- 2,529 cells/microL, 0.84 +/- 0.83% of which were CD34+, was found. The large majority of CD34+ cells were committed toward initial myeloid differentiation (CD33+, CD13+) and expressed the transferrin receptor (CD71). A substantial proportion of these cells (about 40%) co-expressed CD45RA and CD117, while a very small number displayed markers of advanced myeloid commitment, such as CD14, CD15 and CD41 (less than 2%), or those of lymphoid differentiation: CD2, CD5, CD7, CD10 and CD19 ...

Unrelated umbilical cord blood stem cell transplant after failure of haploidentical or matched unrelated donor hematopoietic stem cell transplant.
Objective The aim of the study was to evaluate the efficacy and safety of umbilical cord blood stem cells (USCs) transplantation combined with routine supportive therapy (RST) for liver cirrhosis (LC). Materials and methods Clinical trials involved in this research were searched from Web of Science, PubMed, EMBASE, Cochrane Library, Wanfang and CNKI database. Treatment effects, quality of life (QoL), adverse events and other outcome measures were extracted and evaluated. Results A total of 10 trials including 616 LC patients were involved in this study. Based on our analysis, the liver function of LC patients was significantly improved after USCs transplantation and RST combined therapy, indicated by decreased total bilirubin, alanine aminotransferase, aspartate aminotransferase levels and prothrombin time and increased serum albumin level and prothrombin activity. Compared to those treated by RST alone, patients treated by combined therapy

A cord blood bank is a facility which stores umbilical cord blood for future use. Both private and public cord blood banks have developed in response to the potential for cord blood in treating diseases of the blood and immune systems. Public cord blood banks accept donations to be used for anyone in need, and as such function like public blood banks. Traditionally, public cord blood banking has been more widely accepted by the medical community. Private cord blood banks store cord blood solely for potential use by the donor or donors family. Private banks typically charge around $2,000 for the collection and around $200 a year for storage. The policy of the American Academy of Pediatrics states that private storage of cord blood as biological insurance is unwise unless there is a family member with a current or potential need to undergo a stem cell transplantation. The American Academy of Pediatrics also notes that the odds of using ones own cord blood is 1 in 200,000 while the Institute ...
Tens of thousands of patients need bone marrow transplants (BMT) every year, some for bone marrow (BM) cancers and some for inherited diseases such as sickle cell anemia and thalassemia, but many lack a BM donor. African Americans, Asian Americans, and people of Hispanic descent are more likely than others to lack a stem cell donor. BMTs provide hematopoietic (blood) stem and progenitor cells (HS/PCs) that replace the patients diseased BM with healthy BM. The new BM provides all the circulating blood cells throughout life. Many BMTs use HS/PCs that do not come from the BM. One such other source is umbilical cord blood (UCB). UCB HS/PCs have many advantages over other HS/PC sources (i.e., BM or peripheral blood). For example, we can easily obtain UCB HS/PCs without any risk to the donor, and we can keep the cells stored in freezers to be available when a patient needs them.

Background: Measures were introduced in both the House and Senate to establish a National Cord Blood Stem Cell Bank Network.. Umbilical cord blood stem cells are obtained from the blood contained in the delivered placenta and umbilical cord, which are normally discarded after childbirth. Obtaining these stem cells presents no inherent moral concerns. Through freezing they can be preserved for many years.. According to findings presented in the House measure, cord blood stem cell transplants can be used for bone marrow reconstitution to treat malignancies such as leukemia and lymphoma, genetic disorders such as sickle cell anemia, and acquired diseases. The findings also claim that cord blood stem cells do not have to be matched as closely as bone marrow transplants. This means patients will be more likely to find a suitable unrelated cord blood donor than a matched bone marrow donor. Supporters say a network of at least 150,000 units of ethnically balanced cord blood donors would provide ...
The University of Colorado Cord Blood Bank (UCCBB), a major component of ClinImmune Labs, has a seventeen year history of collecting, processing, banking and distributing cord blood for human transplantation. UCCBB is a public cord blood bank, which has consented 30,000 women and banked over 8,500 cord blood units, of which more than 770 have been transplanted at over 150 different transplant centers in the United States and abroad. UCCBB is a major provider of Hispanic cord blood units to patients in the United States, Mexico, and Central and South America. UCCBB is accredited by AABB and licensed by the FDA (May 24, 2012 Approval Letter-HPC, Cord Blood). The Health Resources and Services Administration (HRSA) awarded UCCBB a cord blood collection contract beginning in 2006. UCCBB provides cord blood to stem cell investigators in Michigan, New York, Tennessee, Washington, and Colorado.

ATLANTA —Twelve percent of adults with acute myeloid or acute lymphoblastic leukemia who received umbilical cord blood transplantation experienced graft failure, according to a large European retrospective study presented at the ASH Annual Meeting and Exposition.“Our aim was to assess the outcomes of patients with acute leukemia who experience graft failure after umbilical cord blood
0054] In important embodiments of the invention, the umbilical cord blood cells are fractionated in order to generate enriched cell populations. As used herein, an enriched cell population is a cell population that has been manipulated in order to increase the frequency of a particular cell type in the population relative to the frequency of that cell type prior to manipulation. It is to be understood that the cell type being enriched is one that existed in the population prior to manipulation, and that enrichment results from the removal of other cell types from the population rather than addition of the cell type of interest. Of particular interest according to the invention are cell populations enriched in CD34+, CD133+, or CD34+/CD133+ cells. CD34 and CD133 are cell surface protein (or markers) that have been identified previously as present on hematopoietic progenitor cells (including on hematopoietic stem cells). As used herein, a CD34+ cell is a cell that expresses CD34 on its cell ...

N2 - During the last decades, extended characterizations were performed of human full-term cord blood (hTCB) cells, but little information is available on human early preterm cord blood (hEPCB) hematopoietic stem cells (HSCs). In our study, we analyzed by flow cytometry 19 hEPCB and 17 hTCB samples. First, we observed that the percentage of CD34 PosCD45 Dim cells was higher in hEPCB compared with hTCB and that it decreased during 16th-20th week of pregnancy. Within the CD34 PosCD45 Dim population, we examined the expression of CD29, CD31, CD38, CD90, CD117, CD133, CD135, CD200, CD243, and CD338. We found that CD135 ...
Wise presentation at is the first verified CNS nerve regeneration info weve seen. His procedure being: 1. filter out mononuclear cells from HLA-matched umibilical cord blood 2. open the spinal cord dura 3. inject the mononuclear cells 3mm into the dorsal root above and below the injury site 4. use lithium carbonate (maybe/maybe not) to stimulate nerve regrowth - still trialling this plus other grow factors 5. wait for nerves to
The authors induced SCI in 10 dogs by percutaneous balloon compression. The 10 injured dogs were assigned randomly to the following groups (2 dogs each): Group 1, evaluated 2 weeks after sham transplantation; Group 2, evaluated 2 weeks after transplantation; Group 3, evaluated 4 weeks after sham transplantation; Group 4, evaluated 4 weeks after transplantation; and Group 5, evaluated 4 weeks after multispot transplantations. The dogs with sham transplantation (Groups 1 and 3) received the same volume of saline, as a control. A spinal needle was advanced into the spinal canal, and the investigators confirmed that the end of the spinal needle was located in the ventral part of spinal cord parenchyma by using contrast medium under fluoroscopic guidance. The hUCB-derived MSCs were transplanted into the cranial end of the injured segment in 6 injured dogs at 7 days after SCI. ...
Although cord blood is currently considered discarded human material, it should only be collected for banking with an institutional review board-approved protocol and with signed informed consent from a parent.42,43 Pertinent donor information communicated to the cord blood bank should be kept confidential by the cord blood bank and used only to report important medical information obtained during the cord blood collection, processing, and screening process that is relevant to the safety of the donor and family. If cord blood was collected from a newborn who subsequently developed a genetic, immunologic, or malignant neoplastic disorder, parents should notify the cord blood bank so that the unit is not used for transplantation. All cord blood units banked for potential use should be tested for infectious diseases, similar to those tested in a blood bank, and for hereditary hematologic diseases. The informed consent must contain information pertaining to what tests are to be performed on the cord ...
There was nothing unusual about the birth of a baby girl in Sacramento one Friday afternoon late in October, 2012. This birth was special, however, because just a few hours later both Priscilla Williams (BME & DEB graduate student) and Eduardo Silva (BME & DEB Assistant Professor) were busy isolating stem cells from the babys umbilical cord blood. The Silva Lab is one of the first recipients of cord blood from the recently established Umbilical Cord Blood Collection Program.. The Silva Labs current project will isolate vascular progenitor cells from the cord blood with the premise that they can investigate and develop new strategies to actively direct their homing in vivo. In the near future, Silvas group will isolate not only vascular progenitor cells but also other progenitor and stem cell populations. For example, in the next couple of months the Silva Lab and Scott Simons Lab will collaborate to develop strategies to isolate hematopoietic stem and progenitor cells (HSPCs) and ...
To determine if overweight/obese pregnant women have altered microRNA expression patterns in fetal umbilical cord blood that may affect the development of offspring. Umbilical cord blood samples were obtained from the fetuses of 34 overweight/obese and 32 normal-weight women after delivery. Next generation sequencing (NGS) analyzed their miRNA expression patterns. miRanda and TargetScan databases were used to predict the miRNAs target genes followed by analyses of Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) to perform function grouping and pathway analyses. qRT-PCR verified the identity of differentially expressed miRNAs that were revealed in the NGS results. There was a positive correlation between newborn body weight and pregestational BMI of pregnant individuals (r = 0.48, P | 0.001). One hundred and eight miRNAs were differentially expressed between the normal and overweight/obese groups, which target genes were enriched in the metabolic pathway. Five C19MC miRNAs (miR
Cord blood is obtained after the umbilical cord has been cut. The blood is frozen and can be stored in cord blood banks either privately or be donated to public cord blood banks.
Intrauterine exposure to gestational diabetes mellitus (GDM) confers a lifelong increased risk for metabolic and other complex disorders to the offspring. GDM-induced epigenetic modifications modulating gene regulation and persisting into later life are generally assumed to mediate these elevated disease susceptibilities. To identify candidate genes for fetal programming, we compared genome-wide methylation patterns of fetal cord bloods (FCBs) from GDM and control pregnancies. Using Illuminas 450K methylation arrays and following correction for multiple testing, 65 CpG sites (52 associated with genes) displayed significant methylation differences between GDM and control samples. Four candidate genes, ATP5A1, MFAP4, PRKCH, and SLC17A4, from our methylation screen and one, HIF3A, from the literature were validated by bisulfite pyrosequencing. The effects remained significant after adjustment for the confounding factors maternal BMI, gestational week, and fetal sex in a multivariate regression model. In
BACKGROUND: Because there are lower incidence of graft versus host disease in HLA mismatched cord blood transplantation compared to bone marrow transplantation, development of smaller scale cord blood bank could be possible. So we analysed the content of hematopoietic stem cell in cord blood and the distribution of HLA as a basic study for cord blood bank. METHODS: Seventy eight cord bloods were collected in heparinized bottle immediately after caesarian section. After expulsion of placenta, additional cord blood and placental blood were collected with heparinized syringe. Fifteen mL was sent to the laboratory for analysis and the rest was cryopreserved. RESULTS: The mean collected cord blood volume was 96.8mL (range, 55~163mL). And mean 81.8mL (range, 40~148mL) was cryopreserved. It contained mean 7.4x108 (range, 2.8x108~12.2x108) nucleated cells. In 2x105 mononuclear cells, 85 +/- 48 BFU-E, 19 +/- 17 CFU-E, 107 +/- 73 CFU-GM and 124 +/- 113 CFU-GEMM were present. With dextran/albumin thawing ...
The use of cord blood cells as hematopoietic stem cell grafts for patients with hematologic malignancies receiving an allogeneic stem cell transplant has been limited to children due to the small number of stem cells present in a single cord blood collection. The result of these limitations has been a high rate of graft failures in adult patients.. To overcome these limitations, researchers from the Icahn School of Medicine at Mount Sinai in New York City treated CD34-positivecells with a combination of histone deacetylase (HDAC) inhibitors and valproic acid. They found that the treated cells produced a greater number of repopulating cells, and established multilineage hematopoiesis in primary, secondary, and tertiary immune-deficient mice. The findings may provide clinical benefit for adults with leukemia, lymphoma, and other blood cancers. The study is published in The Journal of Clinical Investigation.. Study Methods and Results. The researchers treated dividing cord blood CD34-positive cells ...
Consider the following example. Many cellular therapeutic laboratories measure viability by staining cells with 7-AAD and flow cytometry. This method is used because, in hematopoietic stem cell processing laboratories, viability can be easily combined with other cell membrane markers, such as CD34 and CD45 in a single flow cytometric enumeration panel. This type of viability testing is regularly used for bone marrow, mobilized peripheral blood and umbilical cord blood stem cell products. Virtually all cord blood products are cryopreserved and can remain in the frozen state for many years. In the example shown in the accompanying graph, 56 cryopreserved cord blood samples were thawed, the mononuclear cells (MNC) fractionated by density gradient centrifugation and tested for viability using 7-AAD as well as measuring the proliferation, cellular functionality and viability using HALO®-96 SPC-QC. The discrepancy between dye exclusion and metabolic viability methodologies is readily apparent. In ...
Umbilical Cord Blood is the leftover blood in the umbilical cord and the placenta after the delivery of a baby and the cutting of the cord. Cord blood is generally discarded along with the placenta and the umbilical cord. When the fetal develops, the umbilical cord blood banking hails from the similar zygote as that of the human fetus comprising two umbilical arteries and one umbilical vein, concealed within Whartons Jelly. The fetus, oxygen and nutrient blood is supplied by the umbilical from the placenta. On the contrary, in case of the umbilical artery, the blood oxygen comes from nutrients.. After the successful 10 years of over 1500 stem cell transplantations, the release of stem cells from the umbilical cord blood appears nothing less than a miraculous drug for treating many dangerous diseases. Cord blood constitutes a majority of stem cells and thus, posing as a life-saving amazing technique for your baby and your family. In effect, all mothers and around half of their siblings are ...
Our data shows that EPCR represents a novel robust marker for expanded human LT-HSCs. In UM171-treated cultures, positivity for EPCR defines a highly HSC-enriched population, which includes most repopulating units. EPCR+ cells are uniformly positive for CD34, CD90, and CD133 and represent a subset of this triple positive population. EPCR is thus the most reliable indication of expanded human CB HSCs, especially in the presence of UM171. The utility of this marker to detect expanded HSCs is less obvious when using fresh CB cells because EPCR levels are lower in these cells (supplemental Figure 15; supplemental Table 6). Nonetheless, nonexpanded CB CD34+EPCR+ cells express HSC surface markers, such as CD90, CD49f, CD133, and ckit (supplemental Figure 16), and can repopulate secondary recipient mice (supplemental Figure 15), suggesting that EPCR also identifies LT-HSCs under these conditions. Using the EPCR marker as a tool to monitor ex vivo HSPC activity, we determined that EPCR-positive cells ...

  • This is the first study to report umbilical cord androgen levels in a large unselected population of neonates using LC-MS/MS. Our findings suggest that previous studies have over-estimated cord androgen levels, and that fetal, maternal, and obstetric factors influence cord androgen levels differentially. (
  • These findings suggest, that fetal and maternal CBG- and SHBG-levels are independently regulated. (
  • We turn the signal from the photodetector into a voltage that can be read, processed and turned into a number for oxygen saturation of the blood," he said. (
  • Also called fetal oxygen saturation monitoring . (
  • Blood pressure is one of the vital signs , along with respiratory rate , heart rate , oxygen saturation , and body temperature . (
  • Fetal cardiac output and its distribution were measured before and during infusion of angiotensin II by the radionuclide-labeled microsphere technique. (
  • Blood pressure is influenced by cardiac output , total peripheral resistance and arterial stiffness and varies depending on situation, emotional state, activity, and relative health/disease states. (
