PROGENITOR CELLS VERSUS STEM CELLS Like stem cells, progenitor cells have a capacity for Self-renewal and Differentiation , although these properties may be limited. Embryonic Stem Cells are true stem cells in that they are pluripotent and show unlimited capacity for self-renewal. In contrast, many cells termed Adult Stem Cells would be better defined as progenitor cells, as their capacities for unlimited self renewal and plasticity have not been comprehensively demonstrated. FUNCTION OF PROGENITOR CELLS The majority of progenitor cells lie dormant or possess little activity in the Tissue in which they reside. They exhibit slow Growth and their main role is to replace cells lost by normal attrition. Upon tissue damage or Injury , progenitor cells can be activated by Growth Factors or Cytokines , leading to increased cell division important for the repair process. EXAMPLES OF PROGENITOR CELLS
