BACKGROUND: Peripheral blood stem cells (PBSCs) collected from granulocyte-colony-stimulating factor (G-CSF)-mobilized donors are routinely used for hematopoietic stem cell transplantation. Most PBSC collections worldwide have used the COBE Spectra (COBE) platform that is being replaced by the Spectra Optia (OPTIA). This study compared the PBSC collection performance and safety of the OPTIA using a single-step, continuous mononuclear cell (CMNC) collection procedure and the standard COBE MNC procedure...

For successful bone marrow transplantation it is necessary to obtain enough progenitor cells during the bone marrow (BM) harvesting procedure. Most centers are using multiple aspirations of maximum 2 ml BM (A), while other centers are using few larger amount aspirations for BM harvesting (B). There is still a discussion about possible differences in graft composition between A and B. To evaluate the feasibility in children we evaluated twenty BM harvestings that were performed in 18 donors, 7 autologous (median age 6...

Previously, chemical analysis of gastric fundic mucin showed that infection of sheep with Haemonchus contortus or Teladorsagia circumcincta changed the proportions of monosaccharides and decreased terminal mucin fucosylation and sialylation. To identify the effects of these parasites on the two mucin-secreting cell lineages, fundic and antral tissues were collected for histochemistry from 69 lambs aged from 3-4 to 9-10 months-of-age which had received a single infection of either H. contortus or T. circumcincta and euthanased at Day 21 or 28 post- infection respectively...

BACKGROUND: A better understanding of mechanisms underlying dose-effects of probiotics in their applications as treatments of intestinal infectious or inflammatory diseases and as vaccine adjuvant is needed. In this study, we evaluated the modulatory effects of Lactobacillus rhamnosus GG (LGG) on transplanted human gut microbiota (HGM) and on small intestinal immune cell signaling pathways in gnotobiotic pigs vaccinated with an oral attenuated human rotavirus (AttHRV) vaccine. RESULTS: Neonatal HGM transplanted pigs were given two doses of AttHRV on 5 and 15 days of age and were divided into three groups: none-LGG (AttHRV), 9-doses LGG (AttHRV + LGG9X), and 14-doses LGG (AttHRV + LGG14X) (n = 3-4)...

CONTEXT: Since the syndrome of hypogonadotropic hypogonadism (HH) is associated with anemia and the administration of testosterone restores hematocrit to normal, we investigated the potential underlying mechanisms. DESIGN: Randomized, double blind, placebo controlled trial. METHODS: We measured basal serum concentrations of erythropoietin, iron, iron binding capacity, transferrin (saturated and unsaturated), ferritin and hepcidin and the expression of ferroportin and transferrin receptor (TR) in peripheral blood mononuclear cells (MNC) of 94 men with type 2 diabetes...

BACKGROUND: Extracorporeal photopheresis (ECP) is an effective cell therapy employed in several diseases, including graft versus host disease (GVHD) and organ rejection. When ECP is performed using an off-line technique, mononuclear cell (MNC) collection by leukapheresis is necessary for further manipulation (addition of 8-methoxypsoralen and ultraviolet A irradiation before reinfusion to the patient). We report the results of the first crossover equivalence study on yield and purity of MNCs collected from patients undergoing ECP with two different automated systems: MNC and CMNC (working with intermittent and continuous-flow collection, respectively), released by Terumo BCT...

Umbilical cord blood (CB) is considered one of the youngest available sources of adult stem cells. Besides hematopoietic stem cells, CB has been shown to contain endothelial progenitor cells as well as mesenchymal stromal/stem cells (MSC). To isolate MSC from cord blood, CB is collected into a sterile bag containing the anticoagulant citrate-phosphate-dextrose (CPD). The CB is then processed by density-gradient centrifugation to obtain mononuclear cells (MNC). These are cultured until the outgrowth of fibroblastoid cell colonies appears...

Terumo BCT recently introduced a new system for mononuclear cell (MNC) collection that uses a Spectra Optia apheresis machine equipped with a redesigned disposable kit and software program (version 11.2). It allows for the continuous collection of MNCs, unlike the original Spectra Optia system (version 7.2), which included a chamber for two-step cell separation. The aim of this study was to compare the two apheresis systems in regard to specific performance parameters. A retrospective data analysis of 150 patients who had undergone peripheral blood stem cell collection between March of 2014 and May of 2015 at our institution was performed...

BACKGROUND: Collection and processing characteristics influencing quality of cord blood (CB) units play an essential role to cord blood banks (CBBs). At many CBBs, volume reduction is performed using hydroxyethyl starch (HES) and the Sepax (Biosafe) automated cell processing system. Due to the withdrawal of HES from the European market, a validation of the nonHES protocol was performed. METHODS: This partially retrospective study identified CB characteristics such as gestational age and CB volume/cell count correlated with higher quality...

Biomedical implants have been widely used in bone repair applications. However, nanosized degradation products from these implants could elicit an inflammatory reaction, which may lead to implant failure. It is well known that the size, chemistry, and charge of these nanoparticles can modulate this response, but little is known regarding the role that the particle's morphology plays in inducing inflammation. The present study aims to investigate the effect of hydroxyapatite nanoparticle (HANPs) morphology on inflammation, in-vitro and in-vivo...

BACKGROUND: In Germany, cord blood needs to be transported to the processing facility to be processed and cryopreserved within 48 hours after collection according to national guidelines. During that time, a temperature of 22 ± 4 degrees C must be maintained. The purpose of this study was to analyse the influence of temperature during transport and storage prior to processing and cryopreservation on stem cells in 2460 both autologous and allogeneic umbilical cord blood samples. METHODS: Total and viable CD45+ cells, total and viable CD34+ cells, and mononuclear cells (MNC) of cord blood and resulting leucocyte concentrate both before and after freezing were analysed by flow cytometry...

Regenerative medicine studies using autologous bone marrow mononuclear cells (BM-MNCs) have shown improved clinical outcomes that correlate to in vitro BM-MNC invasive capacity. The current Boyden-chamber assay for testing invasive capacity is labor-intensive, provides only a single time point, and takes 36 hours to collect data and results, which is not practical from a clinical cell delivery perspective. To develop a rapid, sensitive and reproducible invasion assay, we employed Electric Cell-substrate Impedance Sensing (ECIS) technology...

Neisseria meningitidis serogroup B (MnB) is a leading cause of bacterial meningitis; however, MnB is most commonly associated with asymptomatic carriage in the nasopharyngeal cavity, as opposed to the disease state. Two vaccines are now licensed for the prevention of MnB disease; a possible additional benefit of these vaccines could be to protect against disease indirectly by disrupting nasopharyngeal carriage (e.g., herd protection). To investigate this possibility, accurate diagnostic approaches to characterize MnB carriage isolates are required...
