Stem cells characterize as a primitive cells and have the ability to divide
and make new stem cells similar to it or produce different specialized cells , so
these cells remained unspecialized until receive special signals push it to
evolutes into special cell. Most studies on the animal cell indicated that the
presence of this stem cells which able to differentiation to any kind of body
cells. Experiments revealed the ability of these cells to transform to any tissue
or special organ in the body like, heart, muscle and nerve cells, and these
discoveries bring back the hopes to use stem cells medically to compensated the
damage part and curing some dangerous diseases like , autoimmune diseases ,
diabetes , Parkinson's , and other diseases , in addition knowing other different
kind neither it is embryonic , germen , adult, or cancer cell, and cellular
organization ways and modern techniques about discover it through use
surface marker or genetic engineering techniques and prevent moral fears that
connected to take these cells from the embryo. This still continuous to find
many molecular properties which characterizes stem cells and investigate new
mechanism for different cellular treatment of dangerous disease which still
under research and discovery.
