  • She is focusing on a type of cell called Müller glia, which in frogs and fish become activated in response to retina damage. (sunnybrook.ca)
  • Once activated Müller glia become stem cells that can form retina cells and replace the cells that were destroyed in the injury. (sunnybrook.ca)
  • Her work thus far has focused on generating functional retina cells in a Petri dish. (sunnybrook.ca)
  • Preliminary work transplanting these cells into the retina of preclinical models has shown that the technique works, albeit at a very low efficiency. (sunnybrook.ca)
  • What we would like to do is inject our cells into the retina and see whether using [focused] ultrasound is a better way of getting the cells in," says Schuurmans. (sunnybrook.ca)
  • Müller cells are the principal glial cells in the retina. (molvis.org)
  • In biology , a tissue consists of a group of similar cells and their intercellular material that work together to perform a function. (britannica.com)
  • I knew that my technical training as a molecular neurobiologist had prepared me well to fill this niche-I just needed to learn about glial biology. (nih.gov)
  • In the Drosophila central nervous system (CNS) glial cells are known to be generated from glioblasts, which produce exclusively glia or neuroglioblasts that bifurcate to produce both neuronal and glial sublineages. (biologists.com)
  • We show that the genesis of a subset of glial cells, the subperineurial glia (SPGs), involves a new mechanism and requires Notch. (biologists.com)
  • This study indicates that glia are not only essential to neural transmission, but also suggest that the development of human cognition may reflect the evolution of human-specific glial form and function," said University of Rochester Medical Center (URMC) neurologist Steven Goldman, M.D., Ph.D., co-senior author of the study.

  • For intracellular transportation, Professor Huang has been working on illustrating the functions of a microtubule-based motor molecular, Kinesin-1, in different cell types, which is aimed at understanding its roles in different cell types in development and disease. (hku.hk)
  • As a next step, Doetsch would like to specifically trace these new glial cell types and to investigate their roles in normal brain function and how they respond in different physiological contexts. (clinlabint.com)
  • Cell viability, morphology, oxidative stress, inflammation, cell cycle, and specific glial markers were evaluated using RT-qPCR and high content analysis (HCA) approaches. (hal.science)
  • What was very unexpected was that one glial cell type was found attached to the surface of the wall of the brain ventricle, rather than in the brain tissue. (clinlabint.com)
  • They develop from a type of glial cell called an ependymal cell. (macmillan.org.uk)
  • Although wild-type huntingtin is expressed in all cell types, with the highest concentration in the brain [ 7 ], its functions are not yet fully understood [ 8 ]. (hindawi.com)
  • The cells of this tumor type form a circular pattern called rosettes. (nih.gov)
  • They are the first-line defense innate immune cells, commonly regarded as "brain resident macrophages" and the sole resident immune cell type in the CNS 4 . (atlasantibodies.com)
  • We seek to combine the isotropic fractionator that allows estimation of neuronal and glial cell numbers and distributions across hundreds of species with whole-brain labeling, clearing and automated light microscopy methods that allow quantitative whole-brain mapping of cell type distributions. (lu.se)
  • These cells are continuously bathed by cerebrospinal fluid and interact with axons from other brain areas, and therefore are poised to sense and integrate multiple long-range signals. (clinlabint.com)
  • Neurotropic viruses can cross the otherwise dynamically regulated blood-brain barrier (BBB) and affect the brain cells. (bvsalud.org)
  • The blood-brain barrier is necessary because in the brain, unlike in most of the body, the cells that form the capillary walls are tightly sealed, for example, to protect it from harm caused by toxins and infections. (msdmanuals.com)
  • Therefore, phycotoxins can reach cells underlying the epithelium, such as enteric glial cells (EGCs), which are involved in gut homeostasis, motility, and barrier integrity. (hal.science)
  • Meningiomas , as defined by the 2016 World Health Organization (WHO), are "a group of mostly benign, slow-growing neoplasms that most likely derive from the meningothelial cells of the arachnoid layer. (medscape.com)
