  • These problems could be solved if we had a method to grow human heart cells from people with genetic LQTS mutations, so that we know the exact test conditions that would reflect the human disease. (ca.gov)
  • Our long-term goal is to develop a panel of iPS cell lines that better represent the genetic diversity of the human population. (ca.gov)
  • These studies will provide the foundation for an expanded panel of iPS cell lines from people with other genetic mutations and from people who have no genetically defined risk factor but still have potentially fatal drug-induced LQTS. (ca.gov)

  • Such a description excludes diseases in which infiltration of these cells occurs in response to a primary pathology. (medscape.com)
  • However, patient-derived cells may be more prone to develop disease-associated pathology after grafting. (lu.se)
  • Lastly, we evaluated the strategy of knocking out a-syn as a means to protect the cells from transfer of pathology upon grafting. (lu.se)
  • It is an embryonal malignancy of the sympathetic nervous system arising from neuroblasts (pluripotent sympathetic cells). (medscape.com)
  • Cadaver-collected fibroblasts can be reprogrammed into induced pluripotent stem cells using chemicals known as growth factors that are linked with stem cell activity. (livescience.com)

Historically, this concept is highlighted by the experi- factors are key intrinsic regulators of these fate decisions and mental phenomenon of lineage reprogramming, for example, that fate choice involves modulating networks of transcription by the conversion of fibroblasts to muscles cells following trans- factors. (lu.se)
  • In order for them to be developed from stem cells, they need a very specific environment in which signals from hormones or proteins trigger the required morphological and functional transformation. (izw-berlin.de)
  • Because PGCs are the founder population for gametes, this accomplishment paves a way to produce functional gametes from induced pluripotent stem cells from northern white rhinos which will contribute to the effort to rewind their extinction. (izw-berlin.de)
  • However, creating fully functional cardiac cells can be a challenge. (medgadget.com)
  • Unfortunately stem cell therapeutics don't have high success rates partly because the cells are not mature and fully functional. (medgadget.com)
  • This results in more robust, mature and functional cardiomyocyte-like cells. (medgadget.com)
  • This indicates that the human and mouse cells were communicating with each other, demonstrating functional as well as structural integration. (ox.ac.uk)
  • The limitation in using stem cells to produce platelets has been the ability to find a method that creates a large number of high-quality, functional platelets. (ibtimes.com)
  • We showed how insulin deficiency in Friedreich's ataxia is likely to evolve, and that a mouse model for Huntington's disease develops diabetes due to loss of beta-cells. (lu.se)
  • All humans start out as only one cell. (healthline.com)
  • Unfortunately, cardiac physiology in animal models (rabbits and dogs) differs from that in humans, and hamster cells lack many key features of human heart cells. (ca.gov)
  • The Japanese government plans to let a stem cell researcher conduct human-animal embryo experiments, with the ultimate goal of someday creating organs to be transplanted into humans. (bigthink.com)
  • If ultimately successful, both approaches would offer access to an unlimited number of implantable islets, representing a significant advance over the multiple human deceased donors that are currently required for islet-cell transplants to be undertaken in humans. (medscape.com)

  • In vitro experiments using NV virus-like particles (VLPs) directly showed NV VLP attachment to HBGA, resulting in VLP internalization into the cell ( 19 ). (cdc.gov)
  • From these critical studies, putative NV receptors were identified, and thus it was hypothesized that a successful in vitro cell culture system would most likely possess these receptors to support NV replication. (cdc.gov)
