摘要: The development and the maintenance of a tissue involves sequential differentiation precursor cells along multiple intermediate stages maturity. At these can proliferate or differentiate depending upon growth signals they receive. Terminally mature lose their ability to proliferate. Alterations occur at level cell whole organism that lead sustained proliferation incompletely cells. This process constitutes an oncogenic event, cellular molecular changes its occurrence are surveyed in this review.
