  • phloem
  • Plants have a conductive tissue, phloem, for transporting sugars and hormones to non-green parts after photosynthesis. (innovations-report.com)
  • Phloem has two basic cell types, enucleate sieve elements (SE) and companion cells (CC). Scientists from the University of Helsinki have developmentally analyzed the process of phloem development in Arabidopsis plant and identified a mutation in a novel gene that is required for instructing phloem differentiation in young, developing plant tissue.

  • target tissues
  • This analysis redirects renin research to renal mechanisms that create the plasma renin level, to renal prorenin biosynthesis and its processing to renin, and to their regulated secretion, extracellular distribution, and possible binding to by target tissues. (ahajournals.org)
  • bypass
  • As we learn from these engineered model tissues and optimize their functions, the long-term objective will be to use these tissues clinically as a replacement in bypass surgery. (uwo.ca)
  • secondary
  • Xyloglucan transglycosylases (XETs) have been implicated in many aspects of cell wall biosynthesis, but their function in vascular tissues, in general, and in the formation of secondary walls, in particular, is less well understood. (diva-portal.org)
  • Furthermore, one of the most abundant XET isoforms in secondary vascular tissues (PttXET16A) was cloned and immunolocalized to fibers at the stage of secondary wall formation. (diva-portal.org)
  • elastin
  • Each of the opposing jaw members includes a non conducting tissue contact surface and an energy delivering element configured to perforate the tissue to create an opening, extract elastin and collagen from the tissue and denaturize the elastin and the collagen in the vicinity of the opening. (google.es)
  • regeneration
  • Theoretically, the use of decellularized matrices of allogenic 10 , 11 or xenogenic 12 , 13 origin is advantageous because they preserve the micro-architecture and composition of the vascular tissue and provide site specific remodeling and regeneration 5 . (pubmedcentralcanada.ca)
  • formation
  • Coordination of cell division and pattern formation is central to tissue and organ development, and is particularly important in plants where walls prevent cell migration. (wur.nl)
  • human
  • Although physiologic pressures were sustained for only 3-6 weeks, they did demonstrate the feasibility of a tissue-engineered graft with human cells. (pubmedcentralcanada.ca)
  • Rand JR, Sussman II Gordon RE, Chu SV, Solomon V (1980) Localization of Factor-VIII-related antigen in human vascular subendothelium. (springer.com)
  • Dr. Kibret Mequanint, Professor in the Department of Chemical and Biochemical Engineering, has received a $252,000 research grant from the Heart and Stroke Foundation of Canada (HSFC) to support his fundamental work on growing engineered blood vessels using human cells and to study vascular disease models and therapeutic strategies. (uwo.ca)
  • In the short term, our research is focused on growing human blood vessels so that these tissues can be used to study different factors that contribute to heart disease," said Mequanint. (uwo.ca)

  • hormones
  • Auxin and cytokinin are both critical for division and patterning, but it is unknown how these hormones converge to control tissue development. (wur.nl)
  • demonstrate
  • Transmission electron microscopy (TEM) reconstructions demonstrate relatively straightforward stylet progression through the extravascular tissue that occurs largely intercellularly. (biologists.org)
  • We further demonstrate that the auxin-cytokinin interaction acts as a spatial incoherent feed forward loop, which is essential to generate distinct hormonal response zones, thus establishing a stable pattern within a growing vascular tissue. (wur.nl)
  • Additionally, we also examined the hemocompatibility and inflammatory potential of CUPE to demonstrate its potential in serving as a blood-contacting vascular graft material. (pubmedcentralcanada.ca)
  • system
  • Which of the following is correctly matched with its tissue system? (jiskha.com)
  • A collection of cDNA libraries from white spruce ( Picea glauca ) and interior spruce ( P. glauca × engelmanii ) vascular tissue were analyzed to identify a set of genes that could serve as tissue-related markers within the coniferous vascular system. (springer.com)
  • infection
  • Other elements that define an ideal biomaterial necessary to the design of a vascular graft are bio-compatibility, infection resistance, suturability and off-the-shelf availability. (pubmedcentralcanada.ca)
  • Black specks appear on the leaves and cause distortion because the infection restricts the expansion of the leaf tissue. (sfgate.com)
