  • 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)
  • Physicians could also extract DNA from the person who is going to receive the cellular transplant - creating a patient-specific treatment - though that would end up being far more expensive than drawing from a library of ready-made cells. (usf.edu)
  • Instead, it may depend on the host and donor molecular similarities or distinctions critical for the organogenesis program. (frontiersin.org)
  • We determine a comprehensive map of lineage-specific lncRNAs in human dermal lymphatic and blood vascular endothelial cells (LECs and BECs), combining RNA-Seq and CAGE-Seq. (nature.com)
  • Thereafter, a distinct subpopulation of endothelial cells lining the cardinal vein starts differentiating by expressing the TF PROX1, the master regulator of lymphatic endothelial cell (LEC) identity, via the TFs SOX18 and COUPTFII. (nature.com)
  • We explored whether LPL affects (a) lipoprotein transport across bovine aortic endothelial cells or (b) lipoprotein binding to subendothelial cell matrix (retention). (jci.org)
  • Moreover, we observed marked genomic instability in mutant cells, which is exacerbated upon inhibition of SOD1. (bvsalud.org)
  • We tested whether the cloned dogs were genetically identical by microsatellite analysis of genomic DNA from the donor Afghan, the cloned dogs and the surrogates (see supplementary information ). (nature.com)
  • A)BACs carry DNA fragments much larger than plasmids or phages and greatly minimize the number of clones needed to make up the genomic library. (easynotecards.com)
