  • In addition to their ability to supply cells at the turnover rate of their respective tissues, they can be stimulated to repair injured tissue caused by liver damage, skin abrasions and blood loss. (thefutureofthings.com)
  • The ability of our body to regenerate some of its tissues is largely owed to the reserves of adult stem cells. (thefutureofthings.com)
  • Internal signals producing apoptosis depend on interactions of several proteins and may serve to protect the organism from cancer by killing cells that have pre-cancerous changes. (agemed.org)
  • reported that anti-RHAMM antibodies block the migration of endothelial cells, which is an important key to the process of tissue injury and angiogenesis (3). (jri.ir)
  • To determine which cells are expressing specific cellular markers and how these cells are organized relative to each other requires volumetric imaging of the pre-implantation embryos by confocal microscopy. (zeiss.com)
  • of the most critical events which lead to tissue patterning involves mechanisms going beyond single cells. (lu.se)
  • Low-quality embryos, on the other cells, thereby maintaining a relatively low basal hand, frequently display morphological level [16-18]. (who.int)
  • The visual input was always tremendously important for me and it still gives me enormous pleasure to look down a microscope at embryos and tissues and wonder how they develop. (biologists.com)
  • The ZEISS Lattice Lightsheet 7 microscope enabled imaging of the entire depth of the embryos with little to no phototoxicity, at the required speed to prevent any motion artefacts, and with minimal loss of signal intensity. (zeiss.com)
  • I remember hearing about Drosophila genes associated with segmentation from David Ish-Horowicz when I was in Mill Hill. (biologists.com)
  • We are also seeing new techniques to transplant ovarian tissue into a woman's arm so that local cancer treatment will not make her sterile. (globalchange.com)
  • These genes translate into the appropriate proteins, known as caseins , that can be extracted and mixed in precise quantities. (crlifesc.com)
  • The major characteristics of Nrf2 are to some extent mimicked by Nrf2-dependent genes and their proteins including heme oxygenase-1 (HO-1), which besides removing toxic heme, produces biliverdin, iron ions and carbon monoxide. (springer.com)
  • In yet another coup for a research concept known as "big data," researchers at the Stanford University School of Medicine have developed a computerized algorithm to understand the complex and rapid choreography of hundreds of proteins that interact in mindboggling combinations to govern how genes are flipped on and off within a cell. (pharmaceuticalintelligence.com)
  • The ENCODE, for the Encyclopedia of DNA Elements , project was a five-year collaboration of more than 440 scientists in 32 labs around the world to reveal the complex interplay among regulatory regions, proteins and RNA molecules that governs when and how genes are expressed. (pharmaceuticalintelligence.com)
  • In this study, the researchers combined data from genomics (a field devoted to the study of genes) and proteomics (which focuses on proteins and their interactions). (pharmaceuticalintelligence.com)
  • Before our work, only the combination of two or three regulatory proteins were studied, which oversimplified how gene regulators collaborate to find their targets," Xie said. (pharmaceuticalintelligence.com)
