«The holy grail in this field,» Kass says, «is to get cells which are every bit as
capable as embryonic stem cells without using embryos at all.»
Not exact matches
Embryonic stem cells are scientifically and medically interesting because they are «pluripotent» (
capable of generating many
cell types), but they are not the same
as totipotent single -
cell embryos.
The act of reprogramming
cells to make them
as capable as ones from embryos apparently can result in aberrant
cells that age and die abnormally, suggesting there is a long way to go to prove such
cells are really like
embryonic stem cells and can find use in therapies.
The
stem cells produced through this therapeutic cloning would, like other
embryonic stem cells, be
capable of developing into many
cell types and serve
as a repair system for whatever part of the body required replenishment at the time.
Derivation of pluripotent
stem cells, either of
embryonic origin or following genetic reprogramming, has opened the path for an alternative source for epidermal
cell therapy
as these
cells are both immortal and pluripotent, theoretically
capable of providing any requested number of
cells of any desired phenotype.
Not so long ago, human
embryonic stem cell (hESC) research and SCNT were being hailed
as the future of regenerative medicine,
capable of generating cures and therapies for any number of diseases and conditions.
