  • List of human cell types derived from the germ layers List of distinct cell types in the adult human body Cabrera O, Berman DM, Kenyon NS, Ricordi C, Berggren PO, Caicedo A (February 2006). (wikipedia.org)
  • Several transcription factors are expressed and repressed in a spatio-temporal manner in order to form and maintain adult pancreatic cell types. (biomedcentral.com)
  • But here we asked if we could find a faster and less invasive approach by using drugs to activate native stem cells already in the adult nervous system and direct them to form new myelin. (innovationtoronto.com)
  • In this study, SIRT1 highly express in pancreatic cancer cells. (cancer-research-network.com)
  • All pancreatic cancer cells were more sensitive to this drug than control HPDE cells. (cancer-research-network.com)
  • The increased threat of venous thromboembolism in cancer patients continues to be related to enhanced tissue factor (TF) procoagulant activity (PCA) on the top of cancer cells. (healthcarecoremeasures.com)
  • In fact, the interaction between PD-1 and PD-L1 allows cancer cells to paralyze the T cells, preventing them from attacking the cancer cells. (scitechdaily.com)
  • Several alkylating agents are commonly used in chemotherapy but may induce DNA damage to cancer cells as well as normal cells. (frontiersin.org)
  • Growing evidence suggests that transcriptional regulators and secreted RNA molecules encapsulated within membrane vesicles modify the phenotype of target cells. (exosome-rna.com)
  • Membrane vesicles, actively released by cells, represent a mechanism of intercellular communication that is conserved evolutionarily and involves the transfer of molecules able to induce epigenetic changes in recipient cells. (exosome-rna.com)
  • Qualitative defects of globin chain synthesis result in hemoglobinopathies such as sickle cell disease . (medscape.com)
  • Studies have shown that cannabinoids can slow down tumor growth in animals and stimulate natural killer cells in humans. (unitedpatientsgroup.com)
  • In these processes, Hes genes function as effectors of Notch signaling, which coordinates cellular events via cell-cell interactions. (biologists.com)
  • Transdifferentiation is a type of cellular reprogramming involving the conversion of one differentiated cell type to another. (silverchair.com)
  • Cellular identity is determined by the transcriptional profile which comprises the subset of mRNAs, and therefore proteins, being expressed by a cell at a given point in time. (silverchair.com)
  • Here, we discuss how transcription factors, and their unique position as the gatekeepers of cellular identity, are exploited in cell reprogramming protocols by exploring work focusing on one reprogramming paradigm - the transdifferentiation of hepatocytes to pancreatic beta cells (β-cell).
