However, it is relevant in biological terms, since it reflects that totipotency of male gametophytes would not be restricted to the stage of vacuolate microspore-early bicellular pollen, as is widely accepted.
Thus the stage of totipotency is leapfrogged in order to go directly to the pluripotent stage.
Self renewal and totipotency are characteristic of stem cells.
These changes in gene expression related transcriptional machinery, chromatin structure and the other cellular functions occurring during several cleavage stages are expected result in a unique chromatin structure capable of maintaining totipotency during embryogenesis and leading to differentiation during the postimplantation development.
The President's Council report draws a critical distinction between pluripotency, the capacity of a cell to give rise to many if not all the different cell types of the human body, and totipotency, the capacity of a zygote or other cell to develop as a complete, integrated, living being.
He posits a hierarchy with absolute strength--called totipotency and represented by the fertilized egg--at one end and absolute weakness--the totally differentiated cells of the developed organism--at the other.
The capability of a single mature plant cell to produce an entire organism is called totipotency.
Crucial to this approach is discovering a way to reverse cell differentiation all the way to pluripotency, but not (as in cloning) even further back to totipotency.
This may perhaps explain why the cells of every tissue, in spite of totipotency, can not be readily cultured (e.
Totipotency is the ability of a cell to regenerate a whole new organism, an identical twin.
A comparative analysis between totipotency and growth environment conditions of the donor plants in tissue culture of Zea mays L.
The latter is indeed "totipotent," but its totipotency arises from a non-totipotent cell.
