Answers (1)

best_answer

The normal cells naturally can stop dividing when they come into contact with other cells, this is the process known as contact inhibition.  This mechanism helps in preventing tissue overpopulation and regulating cell division.  The following steps are included in the mechanism process:

  1. Normal cells divide and multiply until they come into contact with other cells.
  2. The cell division stops upon contact, preventing uncontrolled multiplication. This procedure helps in preserving organ size and tissue shape.

Cells Without Contact Inhibition:

  • Cancer cells have the ability to divide further and maybe form tumors even after coming into contact with other cells.
  • Stem cells: To stimulate tissue regeneration, certain stem cells are able to get stop contact inhibition.
