for many clinical applications. embryonic stem cell, pluripotency Somatic Cell Nuclear Transfer: Mammals have been cloned by somatic
cell nuclear transfer in which the nucleus of an adult somatic cell is transplanted into an enucleated egg. This opens the possibility of therapeutic
cloning in which embryonic stem cells would be derived from a cloned
embryo and used for transplantation therapy of the donor of the adult
nucleus. Although many obstacles need to be overcome, the possibility
of therapeutic cloning holds great promise for the development of new
treatments for a variety of devastating diseases. somatic cell nuclear transfer, therapeutic cloning, reproductive
cloning Induced Pluripotent Stem Cells: Adult somatic cells can be converted to
pluripotent stem cells in culture by four key transcription factors, potentially providing an alternative to embryonic stem cells for transplantation therapy. induced pluripotent stem cell This material cannot be copied, reproduced, manufactured, or disseminated in any
