• desmosomes
  13 July 2003

  Definition: Specialized cell junctions that are formed by desmosomal cadherins and additional associated proteins into which intermediate filaments are inserted. Also known as macula adherens junctions or spot desmosomes.
  Desmosomes are essential adhesion structures in most epithelia that link the intermediate filament network of one cell to its neighbor, thereby forming a strong bond.
  Desmosomes are the most common type of intercellular junction in vertebrate epithelial cells. They are (...)

  Definition: In cell biology, an organelle /ɔːrɡəˈnɛl/ is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.
  Types
  endoplasmic reticulum
  Golgi apparatus
  mitochondria
  peroxysomes
  lysosomes
  Intercellular membrane transport
  Intracellular organelle transport is essential for morphogenesis and functioning of the cell. (...)

  See also : chromatin appearance / chromatin anomalies
  Definition: Chromatin is the DNA/protein/RNA complex extracted from eukaryotic lysed interphase nuclei. Just which of the multitudinous substances present in a nucleus will constitute a part of the extracted material will depend in part on the technique each researcher uses. Furthermore, the composition and properties of chromatin vary from one cell type to the another, during development of a specific cell type, and at different stages (...)
