Cell cycle Regulation

• Cell Division is regulated by protiens in the
  cell called Cyclin. Cylcin tells the cell when
  to divide.
• Cells will stop growing and dividing when they
  come in contact with other cells. This helps
  stimulate healing when there is a wound.
• Other proteins help regulate cell division and
  make sure everything happens in the correct order
• External regulators such as hormones can tell a
  cell when it is time to divide

Cancer

• When cells divide uncontrollably
• Cancer cells do not respond to signals that
  control cell growth and division
• Caner is often linked to a damaged gene p53
  which detects the signals that control growth and
  division
