Totipotent stem cells are produced from the fusion of an egg and a sperm cell.
The discovery of totipotent embryonic stem cells that can potentially be transformed into every possible mature cell type as well as complex tissues and organs, which could then be used to cure diseases and rejuvenate aging humans.
Opponents of embryonic stem cell research are also not likely to be satisfied with the proposal of live embryo biopsy, since each human blastomere is a totipotent cell with the potential to develop into a complete human being.
He makes a case for the advantage of totipotent embryonic stem cells rather than aduk stem cells.
All cells of the early human embryo are totipotent until shortly after the blastocyst stage, including the cells of the inner cell mass and even the primitive germ-line cells.
This approach can work because plant cells are totipotent, meaning that if they are given the right cues, they can grow into an entire new plant.
Plant cells readily become totipotent and function like stem cells.
In other words there is still some "totipotentiality" although such totipotent cells have not been found or purified at this stage of embryonic development.
14) These cells, which are grown in tissue culture and can actually develop into organs, are now referred to as pluripotent rather than totipotent since they are no longer able to develop into embryos.
plants are heavily dependent on the delivery of DNA into totipotent cells within cultured tissues.
What happens when a skin cell turns into a totipotent stem cell [a cell capable of developing into a complete organism] is that a few of its genetic switches are turned on and others turned off," writes University of Melbourne bioethicist Julian Savulescu in the April 1999 issue of the Journal of Medical Ethics.
One of the major technical advances in the cloning of Dolly, the famous sheep born in Scotland in 1997, was getting an adult cell, which had followed biological instructions to perform a specific adult role, to despecialize and perform as a totipotent embryonic cell.
