Abstract The DNA exonuclease three-prime repair 1 (TREX1) is critical for preventing autoimmunity in mice and humans by degrading endogenous cytosolic DNA, which otherwise triggers activation of the innate cGAS/STING pathway leading to production type I IFNs. As tumor cells are prone aberrant accumulation, we hypothesized that they critically dependent on TREX1 activity limit their immunogenicity. Here, show cells, restricts spontaneous pathway, subsequent induction a IFN response. result,...
Cryopreservation is known to destabilise spermatozoa and associated with deficiencies in protamine levels increased DNA fragmentation, which can reduce fertility various species. The objective of this study was evaluate the impact cryopreservation on fragmentation alpaca spermatozoa. A total 108 testicles/epididymides were collected from a slaughterhouse sperm recovered cauda epididymis. Only samples meeting criteria > 10 g weight, 3 cm length, 30% motility, 50 million spermatozoa/mL...
We examined the contribution of fetal membranes, amnion and chorion, to human embryonic hematopoiesis. A population cells displaying a hematopoietic progenitor phenotype (CD34++ CD45low) origin was present in chorion at all gestational ages, associated with stromal or near blood vessels, but absent amnion. Prior 15 weeks gestation, these lacked vivo engraftment potential. Differences chemokine receptor β1 integrin expression profiles progenitors between first second trimesters suggest that...
Animal models are vital to the study of transfusion and development new blood products. Post-transfusion recovery human components can be studied in mice, however, there is a need identify strains that best tolerate xenogeneic transfusions, as well optimize such protocols. Specifically, importance using immunodeficient NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ (NSG) has been questioned. In this study, wild-type NSG mice were compared hosts for transfusions with outcomes quantified by flow cytometric...

Abstract The cryopreservation of hematopoietic cells using dimethyl sulfoxide (DMSO) and serum is a common procedure used in transplantation. However, DMSO has clinical biological side effects due to its toxicity, introduces variation safety risks. Inspired by natural antifreeze proteins, novel class ice-interactive cryoprotectants was developed. corresponding DMSO-, protein-, serum-free media candidates were screened through series assays human cell lines, peripheral blood cells, bone...
Background &amp; Aims Hepatocytic cells found during prenatal development have unique features compared to their adult counterparts, and are believed be the precursors of pediatric hepatoblastoma. The cell-surface phenotype hepatoblasts hepatoblastoma cell lines was evaluated discover new markers these gain insight into hepatocytic phenotypes origins Methods Human midgestation livers four were screened using flow cytometry. Expression over 300 antigens on defined by expression CD326...

A critical barrier to the development of a human immunodeficiency virus (HIV) cure is lack scalable animal model that enables robust evaluation eradication approaches prior testing in humans. We established humanized mouse latent HIV infection by transplanting "J-Lat" cells, Jurkat cells harboring provirus encoding an enhanced green fluorescent protein (GFP) reporter, into irradiated adult NOD.Cg-Prkdc
