  • Interestingly, recent research has shown that inflammation in the brain may trigger neurodegeneration, and a new study from NYSCF Senior Research Investigator Valentina Fossati, PhD , in collaboration with New York University's Shane Liddelow, PhD, finds the first evidence of this phenomenon in human cells. (nyscf.org)
  • Johan Jakobsson, a professor at Lund University and research group leader at Lund Stem Cell Center, explains, "LINE-1 retrotransposons are a rich source of genetic sequences that we suspect have shaped the evolution of the human brain, and we now have the tools to explore their role in brain development. (lu.se)
  • Drs Jordi Soriano, Associate Professor in Physics, and Daniel Tornero, Tenure Track Professor in Biology, both at the University of Barcelona, said: "Our ability to engineer neuronal circuits in a dish and train them to conduct data analysis will provide new insights on how the brain computes information and finds solutions. (eurekalert.org)
  • In theory, transplanting neuronal brain cells could restore at least some brain function, just as heart transplants restore blood flow. (science20.com)
  • Even when the neuronal cells were created successfully, they often died in the brain following transplant-a process called programmed cell death or apoptosis. (science20.com)
  • As a result, we were able to produce neuronal progenitor cells that differentiate into a virtually pure population of neurons and survive inside the brain. (science20.com)
  • The project, funded by the European Commission's Future and Emerging Technologies (FET) programme and involving partner institutions in the UK, France, Spain, Switzerland and Israel, is also expected to produce new knowledge about the functioning of the brain which could be used to develop novel stem cell-based treatments. (eurekalert.org)
  • Further studies showed that the newly discovered stem cell type differs from the known population in its morphology as well as its function. (uni-heidelberg.de)
  • An MRI is better than a CT scan when a brainstem tumor is in the differential diagnosis. (wikipedia.org)
  • Some people say they appreciate life more after a diagnosis of brain stem glioma. (cancer.net)
  • While it is not required for diagnosis or treatment of brainstem glioma, judicious use of biopsy/resection is recommended when safe. (medscape.com)
  • They were long considered to be the only stem cell population in the adult mouse brain as well as the main driver of nerve cell formation," explains Dr Ciccolini. (uni-heidelberg.de)
  • One of the places this happens is the hippocampus, a region of the brain that plays a pivotal role in many learning and memory processes. (myscience.ch)
  • However, despite having the promising outcome of preclinical studies, the clinical application of stem cell therapy remained elusive due to little or no progress in clinical trials. (hindawi.com)
  • However, effective dose and appropriate time of MSCs delivery are the main challenges in the clinical translation of stem cell therapy. (hindawi.com)
  • Stem cell therapy - a bird-brain idea? (sciencelearn.org.nz)
  • An experimental stem cell therapy for the treatment of mild to moderate amyotrophic lateral sclerosis (ALS) received a resounding rejection today from a US Food and Drug Administration (FDA) advisory panel that cited efficacy, safety, and product manufacturing concerns. (medscape.com)
  • The novel approach led to in a new computational model developed by Dr. Srikanth Ravichandran of the Computational Biology Group: "Our model can determine which proteins are responsible for the functional state of a given stem cell in its niche -- meaning whether it will divide or remain in a state of quiescence. (sciencedaily.com)
  • Based on these findings, we propose that this variation in stem cell treatment may facilitate functional recovery and enhanced neuroprotection in aged brains. (medsci.org)
