totipotency

It is possible for a fully differentiated cell to return to a state of totipotency.

This conversion to totipotency is complex, not fully understood and the subject of recent research.

Such cells or nuclei are said to exhibit totipotency.

This capability of total re-generation is called totipotency.

This ability is known as totipotency.

The cells may also be totipotent, but the two researchers were unable for ethical reasons to perform the standard test for totipotency.

In the spectrum of cell potency, totipotency represents the cell with the greatest differentiation potential.

Plant tissue culture relies on the fact that many plant cells have the ability to regenerate a whole plant (totipotency).

As Tudge (1988) discusses, the facility of plants to regenerate from a few cells is related to the characteristic known as totipotency.

This totipotency means that some cells can be removed from the preimplantation embryo and the remaining cells will compensate for their absence.

Research in 2011 has shown that cells may differentiate not into a fully totipotent cell, but instead into a "complex cellular variation" of totipotency.

This reprogramming is likely required for totipotency of the newly formed embryo and erasure of acquired epigenetic changes.

The test for totipotency, developed with mouse embryonic stem cells, is to inject stem cells into another blastocyst.

All cells in a eukaryotic organism have the same DNA but are specified through differential gene expression, a phenomenon known as genetic totipotency.

Epigenetic manipulations may allow for restoration of totipotency in stem cells or cells more generally, thus generalizing regenerative medicine.

Moreover, the cow-egg experiment, like the previous cloning of a sheep, proved that the cycle is reversible: "Committed" adult cells can be restored to embryonic totipotency.

In mammals, most cells terminally differentiate, with only stem cells retaining the ability to differentiate into several cell types ("totipotency" and "multipotency").

Research on Caenorhabditis elegans suggests that multiple mechanisms including RNA regulation may play a role in maintaining totipotency at different stages of development in some species.

Potency is also described as the gene activation potential within a cell which like a continuum begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency and finally unipotency.

It is characteristic of both plant and animal cells; in the latter totipotency is lost at an early stage in embryonic development but in plants all cells maintain this ability throughout the life span of the individual.

Yet it was easy to see how Jenkins could have thought her a woman in the dim starlight, for the mutation that had somehow produced her in spite of her parental totipotency had shaped her into a mockery of human form, and she was as anthropoid as wolfish.
