Regenerative capacity of cells

labile cells

  • constantly dividing
    Examples:
  • epithelium of skin, uterus, GI tract
  • bone marrow

stable cells

quiescence
slow replication to maintain tissue size
Examples:

  • liver
  • endocrine glands
  • renal tubular epithelium

permanent cells

can't proliferate, have left cell cycle
Examples:

  • brain
  • myocardium
  • skeletal muscle cells
