  • The aim of the study was to create a genetically modified clone of mouse stem cells with a conditional knockout of humanized α-synuclein, which can be used for the reinjection into mouse blastocysts, as well as for basic and applied in vitro research in the field of pathophysiology and neuropharmacology.

  • I. Introduction The progress of stem cell research was a significant turning point in history and certainly caught the attention of scientific medicine. (proficientwriters.net)
  • Stem cell research is being followed to achieve medical developments and breakthroughs in science. (proficientwriters.net)
  • Cell culture techniques were advanced significantly in the 1940s and 1950s to support research in virology . (wikipedia.org)
  • This vaccine was made possible by the cell culture research of John Franklin Enders , Thomas Huckle Weller , and Frederick Chapman Robbins , who were awarded a Nobel Prize for their discovery of a method of growing the virus in monkey kidney cell cultures. (wikipedia.org)
  • In particular, Cellular Dynamics International (CDI) has taken lease to approximately 5000 square feet of lab space at the Buck Institute for Research on Aging in Novato, CA. The majority of this space is located within the new CIRM-funded Stem Cell Research Building at the Buck Institute and was extensively reconfigured to meet the specific needs of this grant. (ca.gov)
  • Stem Cell Research? (jewishvaluesonline.org)
  • What is the Jewish perspective on stem cell research? (jewishvaluesonline.org)
  • If embryonic stem-cell research offers real possibilities for future cures then, from a Jewish point of view, it may be pursued with caution, humility, and strict supervision. (jewishvaluesonline.org)
  • Most (but not all) authorities would forbid the creation of embryos with the express purpose of killing them in the pursuit of stem cell research. (jewishvaluesonline.org)
  • The controversy over stem cell research is focused specifically on the use of stem cells taken from embryos. (jewishvaluesonline.org)
  • The data presented in this thesis may serve as valuable resources to help optimize future cell replacement therapies for patients suffering from PD. (lu.se)
  • The term stem cell can be defined by two very important qualities: the cell has the ability to self-renew and, in a more general sense, the cell has not completed differentiation into its final state. (thefutureofthings.com)
  • This general definition includes a wide variety of cells with varying degrees of differentiation potential. (thefutureofthings.com)
  • A key challenge is to understand how state, but must also afford flexibility in cell-fate choice to permit the different cell-fate options confronting stem and progenitor cell-type diversification and differentiation in response to cells are selected and coordinated such that adoption of a given intrinsic cues or extrinsic signals. (lu.se)
  • Evidence the fate of stem cells has broad ramifications for biomedical suggests that during development or differentiation, cells make science from elucidating the causes of cancer to the use of very precise transitions between apparently stable ``network stem cells in regenerative medicine. (lu.se)
  • First, we utilized single cell sequencing to dissect the differentiation of stem cells to midbrain dopaminergic neurons. (lu.se)
  • was found to infect humans. (cdc.gov)
  • CeD is triggered by gluten consumption in genetically susceptible individuals carrying certain major histocompatibility complex (MHC) class II human leukocyte antigen (HLA) variants ( 5 , 6 ). (frontiersin.org)
  • Suspicion and controversy arose in late 2005, when Hwang's collaborator, Gerald Schatten at the University of Pittsburgh, came to know of the real source of oocytes (egg cells) used in the 2004 study. (wikipedia.org)
  • The breakthrough may eventually put to rest the ethical controversy surrounding stem cells. (nih.gov)
  • The mutated mouse stem cells created at EUCOMM will be used to study function. (progress.org.uk)
  • And the article s bold-type tease line goes on to say: The successful cloning of a sheep means humans could be copied but at what cost? (bibliotecapleyades.net)
  • It also means that finally getting the sheep technology to work with cells from adult humans may not turn out to be a turning point for this technology, after all. (usf.edu)
  • This procedure of producing a line of genetically identical cells from a single altered cell, called cloning, made every cell in the culture a miniature factory for producing interferon. (biologywriter.com)
  • Because of Proposal 2, Michigan's great institutions can now compete for those funds, which will accelerate the pursuit for cures and treatments to afflictions such as Parkinson's, Alzheimer's, juvenile diabetes, sickle cell anemia and spinal cord injuries. (blogspot.com)
  • But he says this does mean we could be getting closer to being able to go beyond cloned cell lines to cloning an entire human being. (usf.edu)
  • However, certain factors such as low junctional diversity, thymic selection, and T-cell proliferation upon antigen exposure can affect TCR sharing among individuals. (biorxiv.org)
  • Surprisingly, we find that shared antigen exposure to CMV leads to fewer shared TCRβ clones, even after controlling for HLA, indicative of a largely private response to major viral antigenic exposure. (biorxiv.org)
  • T cells that encounter their specific cognate MHC-presented antigen will bind and proliferate, leading to an immune response. (biorxiv.org)
  • Successful antigen recognition requires T cells to effectively recognize the body's MHC and coordinate a response. (biorxiv.org)
  • have combined two microscopy techniques called 'single-particle tracking' and 'photoactivated localization microscopy' to track how individual molecules of activated Ras move in human cells grown in the lab. (elifesciences.org)
  • From there, the cell constantly removed Ras molecules from these membrane domains and returned them back to their 'fast' diffusing state. (elifesciences.org)
  • T cells mature in the thymus, where their affinity to MHC molecules is tested prior to subsequent release into the periphery. (biorxiv.org)
