Stem Cell terms

  1. Trophectoderm a term used to refer to trophoblast cells in mice.
  2. Trophoblast (TROH-foh-BLAST) A thin layer of cells that helps a developing embryo attach to the wall of the uterus, protects the embryo, and forms a part of the…
  3. Trypsin A proteolytic enzyme that hydrolyzes peptide bonds on the carboxyl side of the amino acids arginine and lysine.
  4. Twinning Development of monozygotic twins, that is, when a very early embryo separates into two pieces, each of which continues development, so that two embryos…
  5. Type-1A diabetes A form of insulin dependent diabetes, usually becoming evident in childhood, resulting from an autoimmune reaction that destroys the pancreatic beta…
  6. Umbilical cord blood stem cells stem cells collected from the umbilical cord at birth that can produce all of the blood cells in the body (hematopoietic).
  7. Umbilical cord stem cells Hematopoietic stem cells are present in the blood of the umbilical cord during and shortly after delivery.
  8. Undifferentiated A term used to describe cells or tissues that do not have specialized ("mature") structures or functions.
  9. Unipotent Refers to a cell that can only develop in a specific way to produce a certain end result.
  10. Unipotent stem cells Stem cells that self-renew as well as give rise to a single mature cell type; e.g., spermatogenic stem cells.
  11. Uterine Pertaining to the uterus.
  12. Vascular Plant tissue specialized for the conduction of water or nutrients
  13. Villi Projections from the surface, especially of a mucous membrane. If the projection is minute, as in a cell surface, it is called a microvillus.
  14. Vimentin The major polypeptide that joins with other subunits to form the intermediate filament cytoskeleton of mesenchymal cells.
  15. Virus (VY-rus) In medicine, a very simple microorganism that infects cells and may cause disease.
  16. White blood cell (WBC) The primary effector cells against infection and tissue damage. WBCs are formed from the undifferentiated stem cell that can give rise to all blood cells.
  17. White Blood Cells Cells that fight infection.
  18. X inactivation The normal inactivation of one of the two X chromosomes in females.
  19. Xenotransplantion A transplant of tissue from an animal of one species to an animal of another species.
  20. Y chromosome See: sex chromosome.
  21. Yolk sac Vital to the embryo for the formation of primordial and other cells that form the embryo. In mammals, it is small and devoid of a yolk.
  22. Zona pellucida A thick, transparent noncellular layer that surrounds and protects the oocyte.
  23. Zygote The diploid cell formed by the fusion of two haploid gamete s during fertilization in eukaryotic organisms with sexual reproduction.
