• osteoclasts
  29 October 2003

  Definition: The osteoclast is the cell responsible for bone resorption. It is derived from hematopoietic progenitor cells that also give rise to monocytes and macrophages.
  Information regarding the molecular regulation of osteoclast formation in humans is limited. In mice, a number of transcription factors, including PU.1 and Fos, are essential for developing an osteoclast phenotype.
  The cytokines and growth factors crucial for osteoclast differentiation and maturation in humans include (...)

• neurons
  25 June 2003

  In the CNS, neurons are topographically organized either as aggregates (nuclei, ganglia) or as elongated columns or layers (such as the intermediolateral gray column of the spinal cord or the six-layered cerebral cortex).
  Functional domains are located in many of these anatomically defined regions (such as the hypoglossal nucleus of the medulla for motor fibers of the twelfth cranial nerve; calcarine cortex of the occipital lobe for primary visual cortex).
  In addition, as a further (...)

  Macrophages exist in almost all animals. In some invertebrates, mesenchymal cells, endothelial cells or fibroblast-like cells can transform into macrophages.
  In vertebrates, primitive macrophages first develop in yolk sac hematopoiesis and differentiate into fetal macrophages. Monocytes are differentiated from hematopoietic stem cells in the late stage of fetal (...)

  Definition: The myocardium is composed primarily of a collection of specialized muscle cells called cardiac myocytes or cardiomyocytes.
  They are arranged largely in a circumferential and spiral orientation around the left ventricle, the chamber that pumps blood to the systemic circulation.
  Cardiac myocytes have five (...)

  WP
  A keratinocyte is the predominant cell type in the epidermis, the outermost layer of the skin, constituting 90% of the cells found there. Those keratinocytes found in the basal layer (stratum basale) of the skin are sometimes referred to as "basal cells" or "basal keratinocytes".
