Stem Cell

Stem cells are cells that have specific functions and are like actors that are awaiting determination of its role. Stem cells expect  for the body signals that to tell them what to do in the body.

 Stem cells have two important characteristics that distinguish them from other cell types, which including:

  A)Cell are not specialized for long periods through cell division renew themselves.

B)Under the conditions of physiological or experimental, They can be induced to become cells  with special functions such as the beating cells of the heart muscle or the insulin-making cells in the pancreas . When the signal reaches the stem cells stem cells, says turn on some of the genes and create new proteins that this proteins helps stem cell like type cell that is supposed to be working.

  What are the unique properties of stem cells?

 Stem cells are different from other types of cells in the body. All  of the Stem Cell types whitout regardless of their origin have three properties .they are  ability to split,self renovation for a long time and non-specialized and can rise to specialized cell types.

   Unlike muscle cells, blood cells, or nerve cells, which usually do not repair themselves,Stem cells are capable of dividing a long time.Stem cells may rebuild own for many times
