Effects of MSC coadministration and route of delivery on cord blood hematopoietic stem cell engraftment

Licencia Creative Commons Reconocimiento-No comercial.-- et al.Hematopoietic stem cell transplantation (HSCT) using umbilical cord blood (UCB) progenitors is increasingly being used. One of the problems that may arise after UCB transplantation is an impaired engraftment. Either intrabone (IB) injection of hematopoietic progenitors or mesenchymal stem cell (MSC) coadministration has been proposed among the strategies to improve engraftment. In the current study, we have assessed the effects of both approaches. Thus, NOD/SCID recipients were transplanted with human UCB CD34+ cells administered either intravenously (IV) or IB, receiving or not bone marrow (BM)-derived MSCs also IV or IB (in the right femur). Human HSC engraftment was measured 3 and 6 weeks after transplantation. Injected MSCs were tracked weekly by bioluminescence. Also, lodgment within the BM niche was assessed at the latter time point by immunofluorescence. Our study shows regarding HSC engraftment that the number of BM human CD45+ cells detected 3 weeks after transplantation was significantly higher in mice cotransplanted with human MSCs. Moreover, these mice had a higher myeloid (CD13+) engraftment and a faster B-cell (CD19+) chimerism. At the late time point evaluated (6 weeks), human engraftment was higher in the group in which both strategies were employed (IB injection of HSC and MSC coadministration). When assessing human MSC administration route, we were able to track MSCs only in the injected femurs, whereas they lost their signal in the contralateral bones. These human MSCs were mainly located around blood vessels in the subendosteal region. In summary, our study shows that MSC coadministration can enhance HSC engraftment in our xenogenic transplantation model, as well as IB administration of the CD34+ cells does. The combination of both strategies seems to be synergistic. Interestingly, MSCs were detected only where they were IB injected contributing to the vascular niche.This study was supported in part by a grant from Gerencia Regional de Salud de Castilla y León (ref.

TEDH y gestación por sustitución

Grado en Derecho. Derecho Internacional Privado Grupo II, 2020-201[ES]Cuando hablamos de gestación por sustitución, observamos que existe una denominación muy variada acerca del tema que hacen referencia a un mismo fenómeno: gestación por sustitución, maternidad subrogada, gestación subrogada, etc. Si bien, de conformidad con la Real Academia Española la gestación por sustitución es definida como el embarazo en el que media un contrato en virtud del cual, la gestante renuncia a la declaración de maternidad del hijo en favor del reconocimiento de la filiación biológica de otras personas, los padres comitentes o intencionales. Si observamos las definiciones que da la doctrina acerca de la gestación por sustitución, todas ellas van a coincidir en la existencia de una serie de aspectos: de un contrato entre las partes, de una gestante, de un progenitor o unos progenitores legales, y de una entrega del bebé cuando finaliza el proceso. Por lo tanto, podemos considerar que estos elementos encuadran la base de la gestación por sustitución

Intermediate Molecular Phenotypes to Identify Genetic Markers of Anthracycline-Induced Cardiotoxicity Risk.

Cardiotoxicity due to anthracyclines (CDA) affects cancer patients, but we cannot predict who may suffer from this complication. CDA is a complex trait with a polygenic component that is mainly unidentified. We propose that levels of intermediate molecular phenotypes (IMPs) in the myocardium associated with histopathological damage could explain CDA susceptibility, so variants of genes encoding these IMPs could identify patients susceptible to this complication. Thus, a genetically heterogeneous cohort of mice (n = 165) generated by backcrossing were treated with doxorubicin and docetaxel. We quantified heart fibrosis using an Ariol slide scanner and intramyocardial levels of IMPs using multiplex bead arrays and QPCR. We identified quantitative trait loci linked to IMPs (ipQTLs) and cdaQTLs via linkage analysis. In three cancer patient cohorts, CDA was quantified using echocardiography or Cardiac Magnetic Resonance. CDA behaves as a complex trait in the mouse cohort. IMP levels in the myocardium were associated with CDA. ipQTLs integrated into genetic models with cdaQTLs account for more CDA phenotypic variation than that explained by cda-QTLs alone. Allelic forms of genes encoding IMPs associated with CDA in mice, including AKT1, MAPK14, MAPK8, STAT3, CAS3, and TP53, are genetic determinants of CDA in patients. Two genetic risk scores for pediatric patients (n = 71) and women with breast cancer (n = 420) were generated using machine-learning Least Absolute Shrinkage and Selection Operator (LASSO) regression. Thus, IMPs associated with heart damage identify genetic markers of CDA risk, thereby allowing more personalized patient management.J.P.L.’s lab is sponsored by Grant PID2020-118527RB-I00 funded by MCIN/AEI/10.13039/ 501100011039; Grant PDC2021-121735-I00 funded by MCIN/AEI/10.13039/501100011039 and by the “European Union Next Generation EU/PRTR”, the Regional Government of Castile and León (CSI144P20).

Metodología para la determinación de modelos de emisión de vehículos turismo en uso real

La contaminación atmosférica en las ciudades, causada principalmente por vehículos turismo, va en aumento a pesar de la renovación del parque de vehículos y del endurecimiento de los límites de emisión. Además, muchos estudios han comprobado que las emisiones en uso real son mayores que las de homologación, por lo que la determinación de modelos matemáticos que permitan conocer y controlar los factores que influyen sobre el consumo y las emisiones contaminantes de los vehículos en tráfico real constituyen una herramienta eficaz para garantizar el control medioambiental. Se trata en esta ponencia de presentar la metodología que se ha desarrollado para la determinación de modelos analíticos que permitan predecir los factores de consumo y emisión de contaminantes en vehículos turismo en tráfico real. Para el presente estudio se ha contado con datos experimentales medidos en un vehículo turismo diésel Euro2 en más de 200 km de recorrido por zona urbana, en el cual se han registrado las emisiones instantáneas y los parámetros de actividad del vehículo. La metodología propuesta explora el uso de ?ventanas de promedio móvil? de tamaño igual a la emisión de CO2 del ciclo de homologación, en las cuales se calculan los factores de emisión y los valores medios de las variables dinámicas del vehículo y del motor. La determinación de los modelos se hace por medio de un análisis estadístico multivariable. Aplicando la metodología propuesta, se obtienen modelos con un elevado grado de ajuste (R2 > 90%) para los factores de consumo y factores de emisión de CO2 y NOx, obteniendo errores de menos del 7% para la predicción basándose únicamente en la velocidad media, la pendiente de la vía y el estilo de conducción. También se comprueba que en condiciones de conducción normal, el factor de emisión de CO2 en tráfico urbano es un 26% mayor y el de NOx un 61% mayor que los factores medidos en las pruebas de homologación, mientras que en condiciones de conducción agresiva, son un 70% y un 113% superiores, respectivamente

Optimization of mesenchymal stem cell expansion procedures by cell separation and culture conditions modification

[Objective]: Optimization of the mesenchymal stem cells (MSC) isolation and expansion method. [Materials and Methods]: Mononuclear cells (MNC) from bone marrow aspirates were obtained by both density gradient centrifugation (standard method) and gravity sedimentation. Cells were cultured in standard conditions (10% fetal calf serum and normal oxygen tension [21% O2]) and expansion results compared to those obtained with the same culture conditions to which platelet lysate (PL) preparations were added; in addition, the 21% O2 concentration was compared to a lower (5%) concentration (hypoxia) until the fourth cell passage. Time of expansion, number of cells obtained, morphology, cell surface markers, and differentiation potential were evaluated. [Results]: MSC obtained by any of the different culture conditions expressed comparable immunophenotype and were able to differentiate into osteoblasts, adipocytes, and chondrocytes. When the number of MSC obtained at fourth passage was analyzed, the highest cell numbers were obtained with gravity sedimentation isolation and PL-supplemented culture and the expansion time was the shortest when cells were cultured under hypoxic conditions. [Conclusion]: MSC isolation by MNC gravity sedimentation together with culture medium supplementation with 5% of PL in a hypoxic atmosphere (5% O2) significantly improved MSC yield and reduced expansion time compared to the standard accepted protocols. © 2008 ISEH - Society for Hematology and Stem Cells.S.

Dynamics of population immunity due to the herd Effect in the COVID-19 pandemic

The novel Coronavirus 2 Severe Acute Respiratory Syndrome (SARS-Cov-2) has led to the Coronavirus Disease 2019 (COVID-19) pandemic, which has surprised health authorities around the world, quickly producing a global health crisis. Different actions to cope with this situation are being developed, including confinement, different treatments to improve symptoms, and the creation of the first vaccines. In epidemiology, herd immunity is presented as an area that could also solve this new global threat. In this review, we present the basis of herd immunology, the dynamics of infection transmission that induces specific immunity, and how the application of immunoepidemiology and herd immunology could be used to control the actual COVID-19 pandemic, along with a discussion of its effectiveness, limitations, and applications.Sin financiación4.422 JCR (2020) Q2, 74/162 Immunology1.296 SJR (2020) Q1, 21/152 Drug DiscoveryNo data IDR 2019UE

Pembrolizumab Plus Gemcitabine in the Subset of Triple-Negative Advanced Breast Cancer Patients in the GEICAM/2015-04 (PANGEA-Breast) Study

The PANGEA-Breast trial evaluated a new chemo-immunotherapeutic combination that would synergistically induce long-term clinical benefit in HER2-negative advanced breast cancer patients. Treatment consisted of 21-day cycles of 200 mg of pembrolizumab (day 1) plus gemcitabine (days 1 and 8). The primary objective was the objective response rate (ORR). The tumor infiltrating lymphocytes (TILs) density and PD-L1 expression in tumor, and the myeloid-derived suppressor cells (MDSCs) level in peripheral blood, were analyzed to explore associations with treatment efficacy. Considering a two-stage Simon’s design, the study recruitment was stopped after its first stage as statistical assumptions were not met. A subset of 21 triple-negative breast cancer (TNBC) patients was enrolled. Their median age was 49 years; 15 patients had visceral involvement, and 16 had ≤3 metastatic locations. Treatment discontinuation due to progressive disease (PD) was reported in 16 patients. ORR was 15% (95% CI 3.2–37.9). Four patients were on treatment >6 months before PD. Grade ≥3 treatment-related adverse events were observed in 8 patients, where neutropenia was the most common. No association was found between TILs density, PD-L1 expression or MDSCs levels and treatment efficacy. ORR in TNBC patients also did not meet the assumptions, but 20% were on treatment >6 months

The datasets presented here were used to generate the main and supplementary figures and tables of the indicated study. The study consists of the identification of genetic markers of cardiotoxicity due to anthracyclines (CDA). CDA is a complex genesis disease or complex trait, and because of this, there is a component of missing heritability. Therefore, it is not possible to identify genetic markers associated with CDA risk. Here, we propose that molecular subphenotypes associated with the CDA may be a strategy for identifying some of this missing heritability and risk markers associated with it. A similar strategy could be applied to identify markers of other diseases of complex genesis. This study is done using a genetically heterogeneous cohort of mice that developed breast cancer and was treated with doxorubicin or a combined treatment of doxorubicin and docetaxel. The mouse cohort was generated by backcrossing, so each mouse is genetically unique. Post-chemotherapy heart damage was assessed by quantifying fibrosis's cardiac area and the thickness of myocardial fibers. The genetic regions associated with CDA were assessed by massive genotyping and genetic linkage analysis. Several molecular subphenotypes were quantified in the myocardium, and their association with the CDA was evaluated. Subsequently, we identified which of them were most statistically associated with CDA in multivariate models. Moreover, which complex trait loci (QTLs) associated with molecular subphenotypes best explained CDA. This strategy served to identify in the cohort of mice genes whose allelic forms could be candidates for the risk of CDA. Allelic variants of these genes were evaluated in four cohorts of cancer patients treated with anthracyclines and whose CDA was evaluated by echocardiography or cardiac magnetic resonance imaging (CMR).JPL laboratory was partially supported by the European Regional Development Fund (ERDF) and the Ministry of Science, Innovation, and Universities (SAF2014-56989-R, SAF2017-88854R), the Carlos III Health Institute (PIE14/00066), "Proyectos Integrados IBSAL 2015" (IBY15/00003), the Regional Government of Castile and Leon (CSI234P18), and "We can be heroes" Foundation.

Genotypes were classified as FVB/FVB (F/F) or FVB/C57BL/6 (F/B). Ultimately, 806 SNPs are informative from the FVB and C57BL/6 mice; the average genomic distance between these SNPs was 9.9 Mb. The genotype proportion among the F1BX mice showed a normal distribution. Linkage analysis was carried out using interval mapping with the expectation-maximization (EM) algorithm and R/QTL software. The criteria for significant and suggestive linkages for single markers were chosen based on Lander and Kruglyak (see methods section of our manuscript).-- Supplemental Dataset 25: Human breast cancer cohort-1 genotyping. The association of genetic variants with CDA was evaluated in four patient cohorts p
